This is how bracelets with stickers came to cheat half the world

by

We are in 2009. Slovakia joins the euro zone, The name of Satoshi Nakamoto It begins to resonate in certain forums, the first Metro line from Andalusia is inaugurated in Seville, Spain gets gold in the Eurobasket and half -world dolls dress with miraculous bracelets called Power Balance. These bracelets, whose price was just 30 euros, promised to improve strength, balance and flexibility thanks to holograms that fixed our biocampus. They also turned out to be a millionaire scam. Power Balance’s story goes back to 2007, when the Josh and Troy Rodarmel brothers founded the company in California. Although the concept was not new, the two brothers developed a marketing campaign that worked perfectly, starting with Give your first 50,000 bracelets in the US Open of Surfing of 2007. Power Balance bracelet | Image: Wagner Bonifacio Leite In just a few months, these bracelets began arriving at personalities dolls such as Michael Jordan, Cristiano Ronaldo, Leonardo DiCaprio and even Shaquille O’Neal, which It appeared on video saying “I don’t give many testimonies, but this does work.” The Power Balance arrived throughout the world, Spain included. Until Infanta Elena had one. In 2010, the company reported some Sales worth $ 35 millionnothing wrong for a product without any scientific basis. Various studies They began to demonstrate that these products were useless, thus arriving the beginning of the end of the company. The key was, undoubtedly, the placebo effect, but that there was a hologram that balanced and isolated frequencies to improve our body was simply false. At the end of 2010The company had to admit that its products were not based on scientific evidence. In 2011, she was sentenced for fraud and forced to pay 57 million dollars. That led Power Balance to bankruptcy. Finally, the company was sold in 2012 to a Chinese company for eight million dollars. The original founders disregard them completely, but the product is still sold today (only without announcing effects of any kind).

“We had an architecture study two days stopped”

by

In recent days, thousands of Spanish companies have been affected by a measure adopted by Movistar, at the request of LaLiga, to combat illegal broadcasts of football matches. The Teleco has begun to block Cloudflare IP addressesa fundamental service that provides security and optimization to a large number of websites. The problem is that these IPS are shared by many totally legal and legitimate services, which causes the blockade to affect business indiscriminately They have nothing to do with illegal football streaming. Not only online stores “We do not give credit. It seems that it was not Spain. It’s crazy,” says Nelson Domínguez, CEO of Docastixa small mobile application development company. Docastix was directly affected over the weekend when one of its customers, in full product launch with an important advertising campaign, discovered that Movistar users could not access their online store. The company was investing in advertising, paying for each click that took potential customers to its website, but Those clicks translated into error pages for Movistar users. “The launch was a disaster,” explains Domínguez. “We have not been able to count that specific impact yet, but it has been high. The campaigns were lost, the clicks and potential purchases were lost. And then our work to put a solution.” Cloudflare panel with the online store data that Docastix speaks. It is appreciated how the 8 (day indicated in the graph) begins the fall and does not begin to trace until 11. The advertising campaign had begun on the 7th (the traffic peak). Ceded image. Movistar’s response to the problem has been confusing. When Domínguez contacted the operator, they asked for his ID and A relationship of all the websites I had tried to access without success. Then they assured that the problem was solved. “We lost four hours of work again,” he says. “Today, what they have done is to implement blockades every 15 minutes. That is not a solution: perhaps a customer can enter to buy, but when he is going to pay he has already stopped working.” Cloudflare sent a hard statement to Xataka in which he accused LaLiga of acting deliberately, knowing the consequences of his blockade: «Although LaLiga perfectly understood that blocking Shared IP addresses would affect the rights of millions of consumers to access hundreds of thousands of websites that do not violate the law, LaLiga continued with said blockade. This seems to reflect the erroneous belief that their commercial interests must prevail over the rights of millions of consumers to access an open internet ». LaLiga, meanwhile, responded to Xataka With another statement in which he attributed cloudflare the responsibility of using his legal clients as “digital shield”: «Given the statements of Cloudflare to Xataka, LaLig legal as a digital shield to protect criminal organizations and mafias ». “LaLiga has repeatedly required Cloudflare to stop this complicit activity with criminal organizations, which threaten intellectual property and incur multiple criminal activities such as the violation of intellectual property, all kinds of scams and pornography, without a favorable response.” “Thus, LaLiga is not positioned against free access to the Internet, but requests measures and carries out controlled actions against companies or organizations that profit from illegal and criminal acts using legal companies as a digital shield.” LaLiga sources add that it is key to understand the role of Cloudflare not only in the illegal retransmission process of parties, but also of the process that follow to house domains. They explain that they are companies that trust Cloudflare, and deserve to know, according to their version, that they are used as a digital shield while it is profitable, hosting and protecting illegal and mafia activities next to the legal companies that are now affected. They speak of intentional complicity. And the impact goes far beyond online stores. Manuel Márquez, Systems Technician Cloudatarecounts serious cases that illustrate the breadth of the problem: “I had an architecture study two days stopped. They are not only websites and stores, but critical business applications for the daily functioning of companies. “Among their business clients have been affected from law firm, which could not access Lexneteven photography studies that depend on cloud services to share files with their customers. And he also affects the solution of fifteen minutes: “The architecture study has already told us that he will report, because they have left them two days,” he says. “We saw that the IPS were blocking every fifteen minutes. Not only do they do it wrong, but they do it wrong and are trying to mask it.” The situation has forced many companies to take drastic measures. Docastix, with only seven employees, has had to dedicate vital resources to move clients out of cloudflare. “Of those seven not everyone can attack the problem by the subject of knowledge, and of which yes, I can only at that time,” Domínguez explains. “We are a very recent small company, there are clients who do not understand this at all and sound a bit of an excuse. It seems that you blame Movistar from a mistake of yours.” The risk of deactivating cloudflare without a previous plan The background technical problem is complex. Cloudflare acts as a security intermediary for a large part of the Internetprotecting companies against computer attacks. As he explains Jaume PonsSystems Engineer in an automotive multinational, “for a small company, something else is unasumable. In the end, if you expose your website directly they lie down if they propose it. You have to use mastodontic suppliers such as Cloudflare, which will provide that first barrier of cybersecurity input. “ The paradox is that some companies, desperate to maintain their operational services, They are choosing to deactivate the protection of Cloudflare, exposing themselves to security risks. “They are actions that no longer end that someone cannot access a service,” Pons warns, “but that companies that have been forced to deactivate protections have been much more exposed to attacks without an adequate plan.” Economic damage multiplies in unexpected ways.

The Board of Directors has officially rejected its offer

by

“OpenAi is not on saleand the Board has unanimously rejected the last attempt of Mr. Musk to alter its competition, ”said Bret Taylor, president of the non -profit organization of the AI ​​company, said Friday, In a message posted in X. In this way, the offer of 97.4 billion dollars launched on February 10 by the CEO of Tesla has been officially discarded by its recipient. This is an important setback for the businessman’s plans and a victory for Sam Altman. Musk gave the impression of being very sure Musk’s purchase attempt seemed to affect the plan set by Altman to transform the startup commercial arm In a public benefit corporation (PBC)liberating it in addition to entity control Nonprofit To get more investments. Musk’s lawyers even said this week that their client would withdraw the offer if the Openai Board promised to “preserve the mission of the beneficial organization and stipulate that the sign of ‘is sold’ for sale ‘of its assets stopping its conversion.” “Openai is not on sale, and the Board has unanimously rejected the last attempt of Mr. Musk to alter its competition. Any possible reorganization of OpenAI will reinforce our non -profit organization and its mission to ensure that Agi benefits all humanity. ” Let us remember that Elon Musk sue Openai and Sam Altman with the argument that the company was moving away from its founding mission to develop AI to “benefit of humanity“And that he had made a” de facto fusion “with Microsoft. Well, it has not been necessary for OpenAi to have to change its plans to avoid the attempt to acquire Musk, but it has been the organization that has directly rejected it, although it is yet to be seen what collateral effect can have this. Although Musk’s present offer has lost validity, there is the possibility that it has influenced the compensation value that Openai must pay to your entity without profit to separate from it.

If it seemed to us that time was driving crazy, we now have a new phenomenon: “The ghost girl”

by

We have spent months Waiting for the arrival of the girl. Countries, agencies and universities have dedicated hours and hours to try to find out how to prepare for what was coming and the truth is that there was not necessary to prepare too much: the girl is being very weak and moderate. Good show of this is that, despite being the great refrigerator of the world, January has been the warmest January of registration. Is it strange? It is not unheard of, of course; But it is not normal. In fact, the NOA “He has expressed his surprise Seeing a strong atmospheric component of the girl without the corresponding colder surface temperature than the average of the tropical Pacific. “ We could say that the phenomenon has been playing with us for weeks. It is as if it were, but without being completely. What will happen to the girl? As Martín León explains“The average of the dynamic IRI model and several models of the Multi-Model set of North America predict an earlier transition to enso-neutral in January-March of 2025”. A priori, the most likely scan is this, but “There is a 41% probability that Emerge Emerge Emerge in this season.” This means that, in aggregate terms, it is expected that “the girls of the girl persist in the short term, with a probable transition to enso-neutral during March-May of 2025 (66% probability).” And then? The international climate community is nervous because we must not forget that the 2023-2024 child was The fifth strongest Since we have records and the fact that the girl is so soft raises many doubts: is it that the Enso is moving towards a structure much warmer What is accustomed to us? It is not clear and is more than a fear than a prediction. But it is clear that what are good news (Few impacts due to a weak girl) It is becoming a source of uncertainty. No one knows if we will end the year in another the child, but the possibility is on the table.

Cupra is not the end of Seat. Cupra gives Seat a future and the future is electric. THE FUTURE IS CUPRA We can set on March 23, 2022 as the day Seat confessed. He did it through his CEO, Wayne Griffiths. That day The statements were pronounced that are on these lines in an event before the press. We didn’t know it yet but it was the first stone of everything that would come later. Almost three years later, we have climbed into Cupra Tavascanthe great electric car of the brand. The one with whom they want to certify what is coupra and where the company walks.

An aspirational car with the feet on the ground “We know how the electric car market is in Spain, we know that the Cupra Tavascan will not be a car with great volumes but it does help us to demonstrate what Cupra is and where we want to go. It is a car that serves us to project and leave Of course you can expect the brand in the future. “ With these words, those responsible for Cupra explained their illusion with the Cupra Tavascan. We talked about how interesting the car seemed to me, of the risky of the proposal and the originality of it, not so easy to find in the market right now. Cupra risk and cupra, for my liking, wins. It makes sense to have put all the meat on the grill with this electric car. Right now, the brand has the Ateca and León coupra as reminiscences of its past. On the way they have added the CUPRA BORN Like its first electric car, the Terramar Cupraas a SUV option for those who do not dare to make the leap to this technology, the Formentor Cupralike the great supervants, and now the cupra tavascan as the great car of its offer. The latter in an electric SUV of 4.64 meters with a Coupé fall and very aggressive appearance in its body, especially in the front. The car shares origin with Volkswagen ID.5 either Skoda Enyaq Coupé But the first impression seen from the outside is that the car has personality, like more or like less. Those same sensations are transmitted to the interior. The dashboard plays with the shapes and is Absolutely dominated by a central column that leaves from the bottom of the screen and in which the button has been arranged Warning. This arrangement creates a kind of triangle that builds the entire central structure under which the wireless load for the mobile phone and two USB-C shots is located. The design helps to separate the spaces of driver and co -driver, giving some sports air that is reaffirmed with copper moldings, the drilled upholstery of the doors with those same small triangles and a steering wheel that leaves two physical buttons to change to change the driving modes. Behind, cams manage energy recovery. It is here where, without a doubt, we have the worst inside. The steering wheel buttons are tactile that we have already seen in other Volkswagen models and that have a haptic response. However, they are not precise, we can unintentionally activate them by maneuvering with the steering wheel and force them to deviate their gaze when we want to select the specific functions. On the left, we have the tactile light selector (which is also not seen with the naked eye from the driver’s position) and the two physical controls for the control of the four windows (skip from one to another activating and deactivating a button that … Indeed, it is tactile). The touch buttons for the lights and controls of the windows come back Ahead, the 5.3 -inch screen remains that detracts from the rest of the cabin. As in Volkswagen’s models, it gives a worse impression because it is not sheltered (as in the Skoda Elroq) and that feeling of going “in the air” increases the difference in size with the huge 15 -inch panel that it has to the right. The head-up Display is good and reads correctly, as in the rest of the German group models. It is worth noting the good work with the central screen. Again, we lack physical buttons to control functions as simple … Read more

The Chinese are traveling in mass to Japan and not just for tourism. Many of them arrive so as not to return

by

Japan is living a boom of “foreigners” arrivals As you never remember. That, as we have explained above, is not always easy, especially at the time of fight between tourism and the life of the premises. This year, in addition, it is special. We are lunar new year, and the volume of travelers has shot a flag above others: China. The funny thing is that many of these visitors are not returning to the nation. Japan: main destination. Nikkei had a few days ago that China’s travel agencies found him: Japan has established itself as the most popular international destination for Chinese tourists During the recent eight -day holiday period, registering twice the reservations compared to the previous year. This growing preference responds to multiple factors, including geographical proximity, cultural attraction and Relaxation of visa restrictions implemented by the Japanese government in 2024. The impact of this opening in the Japanese tourism sector is significant, with an increase in the arrival of Chinese visitors who, if the trend is maintained, could generate substantial growth in the economy of the sector. On the other sidewalk, the decision to facilitate the obtaining of visas has been subject to controversy within the Democratic Liberal Party (PLD)where some conservative sectors consider that the measure was hurried in a context of geopolitical tensions between both countries. What is the new approach to tourism. Japan announced a few weeks ago the implementation of a new visa of multiple tickets with a duration of 10 yearsaddressed to Chinese citizens with high income and significant assets. This measure is part of a set of reforms designed to attract wealthy tourists and stimulate consumption in the nation, in a context of Low internal demand and population aging. In addition to the extended visa, The maximum stay of stay for Chinese tourists traveling in groups will double for 30 dayswith the objective of foster visits to rural destinations and not only to big cities. Other flexibility include the elimination of the employment test requirement for travelers over 65 and the abolition of the rule that forced to use a three -year tourist visa within the first three months after its broadcast. All measures that seek to consolidate Japan as the favorite destination of Chinese tourists, who represented the highest proportion of the 33 million foreign visitors that the country received last year. Live in Japan. But as we said at the beginning, the arrivals of Chinese visitors to Japan are not only temporary. Beyond tourism, a key aspect of the growing link between China and Japan is The increase in the number of Chinese citizens seeking permanent residence in the archipelago. A recent Nikkei report stood out that, at a time of uncertainty about the economic future from China, A growing number of Chinese is choosing to settle in Japan. This phenomenon raises questions about its expectations in a country where the economy has been marked by decades of deflation and salary stagnation. Japan’s appeal as a migratory destination for Chinese not only lies in economic factors, but also in the perception of stability and quality of life. However, this migratory flow also points to Challenges for both Chinese residents and Japanese societywhich has historically maintained a restrictive immigration policy. Art as a gateway. A particularly striking phenomenon is growing amount of young Chinese who see in Japanese art universities a viable path to obtain residence permanent. The recent immigration reform has facilitated access to this status for graduates of these institutions, encouraging a flow of students looking for a future in Japan after finishing their studies. So much, Admission in these universities remains a highly competitive processeven for Japanese students themselves. Getting a place in these higher education centers not only requires academic excellence, but also Advanced artistic skillswhich makes this immigration route accessible only for a select minority. Osaka and China. It is possibly the best example of this exodus. In the last decade, the Chinese community in Osaka has experienced unprecedented growth, duplicating its size and reaching approximately 50,000 residents in 2024according to municipal data. At the moment, The Chinese represent the second largest foreign community in the cityjust behind the Koreans. This increase is driven by that new immigration wave of wealthy people who have acquired homes in the region since the pandemic. Neighborhoods like Nishinari and Naniwa have seen a rapid growth of predominantly Chinese communities, With some areas where up to 90% of residents are of Chinese origin. In these areas, it is common to find schools aimed at the Chinese diaspora, three -story homes with traditional decoration and the presence of businesses that serve the growing community. Connectivity with Kansai International Airport, which allows Shanghai to be reached in just two hours, has been another key factor for this residential choice. The Chinese resident. A study by Professor Toshio Mizuuchi (Osaka Metropolitan University) and the associated professor Lu Lijun (Fukuoka Prefectural University) between 2022 and 2023 analyzed 172 Chinese households in Osaka. The results revealed key trends over this community. In essence, the data reflected that, unlike previous generations of Chinese migrants in Japan, this new wave does not follow the traditional pattern of international students entering the Japanese labor market before settling. On the other hand, from the pandemic, accommodated families have begun to move directly from China without speaking Japanese. Thus, the increase in Chinese tourism and migration in Japan seems to reflect structural changes in the relationship between the two countries, changes marked by both economic opportunities and by the political and social challenges themselves. While Japan looking capitalize The rise of Chinese tourism, long -term migration could redefine work and cultural dynamics within Japanese society.

satellite images show what aim to be their next great aircraft carrier

by

The satellite images of the Shipyard of Dalian, in the province of Liaoning, point to a key advance in China’s naval strategy: the possible construction of their fourth carrier. Known as Type 004, this ship would stand out for integrating an electromagnetic catapult system to launch airplanes and drones, in addition to having a greater displacement than the previous models. It is also speculated with the incorporation of nuclear propulsion, which would mark a significant leap in the operational capacity of the Chinese Navy. As The War Zone points outthe images obtained by Airbus and accessible on Google Earth correspond to last year, although they have recently earned attention. The satellite view suggests that the aircraft carriers continues at an early construction phase, with structures that seem to fit with the catapult system. In addition, models of a J-15 Flanker hunting and a naval helicopter from the Z-8 series have been identified. These types of elements are not accidental: they are usually used in the tests and the development of new aircraft carriers. A project that has been spinning for years Speculation about this aircraft carriers began almost a decade ago and gained strength in 2017, when a porch crane was installed in the Jiangnan shipyard. However, that project did not prosper and the rumors continued to emerge sporadically. It was not until March 2024 when the Admiral and political commissioner of the Chinese Navy, Yuan Huazhi, officially confirmed its existence. He assured that they did not face inconveniences and said that it would soon be announced if the aircraft carrier will have Nuclear propulsion. As we mentioned before, one of the greatest advantages of this aircraft carriers will be its catapult system, which would allow it to be at the level of the American R. Ford in this aspect. This offers key benefits, such as the ability to launch heavier planes. For the Chinese Navy, this means more flight autonomy thanks to a greater fuel load and more weapons capacity. If the nuclear propulsion is confirmed, the ship could operate without geographical restrictions, with a practically unlimited range. The models in Dalian’s shipyard You may ask what kind of aircraft will launch the TyPE 004. For now, there is no official confirmation, but analysts believe they will operate with KJ-600 aircraft, biturbohélice and comparable to the E-2 Hawkeye of the US Navy. These are aircraft of Early Warning and Airborne Controldesigned to provide surveillance, recognition and air space management. Equipped with a long -range radar, they can detect and track both aircraft and enemy vessels at large distances. Although there is no official confirmation, analysts suggest that Type 004 will operate with the furtive hunting J-35, optimized for missions in aircraft carriers and with advanced stealth technology. This would be supported by improved versions of J-15, a versatile hunting adapted to electromagnetic catapults. In addition, the incorporation of unmanned aircraft is expected, expanding their tactical capacities. With this combination, the Chinese Navy would reinforce its air domain in the open sea, integrating manned airplanes and drones in joint operations.

You have never seen a “sell” poster in a luxury mansion: reason here

by

In the same way that it is not usual to find a Special edition of a Lamborghini Miura In a sale concessionaire, it is not easy either Find a mansiona palace or a property of several tens of millions of euros on the adperior advertisement page. Have you wondered the reason? The answer is that, even if they are on sale, that type of luxury houses do not move in the same sale market than the rest. They do it in a secret and much more exclusive. Market, what market? In the field of great fortunes, the discretion is added value. When a millionaire wants to get rid of or buy a new mansion, it goes to a market that is not advertised in real estate portals or advertisements. It is a market that, paradoxically, is Off Market or outside the market. According to ELETER real estate portal data, properties Off Market They suppose around 10% of the public market. Everything is done ‘Sottovoce‘Already through especially discreet real estate agents. This means that you will not see striking photos or signs of “sells” hanging from the windows of those houses. These agents have exclusive listings of properties that only show To people with high purchasing power who have shown interest (and solvency) in buy a property of these features. Privacy, first of all. One of the arguments to choose to sell these properties discreetly is to avoid the “what will say”, on some occasions, and others for preserving their privacy. Verónica Manrique, executive director of Olisson, real estate whose portfolio is composed of 60% by real estate Off Market, declaredto the five days that “in most cases, our clients are entrepreneurs or politicians who value their privacy very much. They do not want people gossiping their homes.” Show How is your homecan expose them to uncomfortable situations before public opinion, so they prefer not to publish photos of their home. In addition, the person in charge of the real estate company said that in this type of transactions it is usual that both real estate agents and those who put the properties for sale, sign confidentiality contracts to prevent the identity of the clients visiting the houses, or Who is the owner. A house full of treasures. Beyond the value of housing itself, the public housing exposure may involve putting at risk the security of the property. Normally, the walls and rooms of these mansions are decorated with pieces of art or other value objects. Also show photos of the different rooms could also give ideas about ways to access the property To friends of others. Manrique said that some clients demanded that the houses that offered them would never have appeared photos of that property in the media, “and it is always easy to meet.” Advantages of Off Market. In addition to the privacy and safety reasons that many ultra -ups have as a flag in any of its financial movements. Realizing a closed and exclusive market generates a “glamor” effect that makes the properties reach a certain status. Some promoters of this type of luxury home prefer to sell their new houses in this market, instead of getting them for sale publicly. In doing so, they adapt to the needs of a certain client profile that only moves in this market. “They are expensive houses and it is not a volume market, you do not need to generate many customers,” declared to Five days Paloma Pérez, Executive Director in Spain of Sotheby’s International Realty. It also has disadvantages. The sale Off MarketIt depends solely and exclusively on the direct contacts of the real estate agents that manage it. So the sale in this market may not be as fast as when it becomes public, where anyone is interested can contact the real estate agent to be interested. This limitation has two variants: on the one hand, exclusivity makes the sale price of the property can be slightly above market valuebut it also makes it more susceptible to the negotiation of the price because the number of potential buyers is also scarce.

We had to observe 4,000 supernovae to realize that something does not fit the explosions of the white dwarfs

by

Approximately a century ago we realized that the universe was not static but extended. Some theories even estimate that it does it at increasing speeds, but measuring this speed has become A major headacheas much as explaining the mechanisms that underlie this cosmic inflation. But maybe we are doing too many turns to the matter. Not so predictable. A study has observed That the supernovae associated with the white dwarf stars are not as predictable as we believed. The study presents us with a problem, and that is that the role of these explosions as markers of the cosmic distance is staggered now. Star milestones. Regular and predictable cosmic objects and events are of great help for astronomers when analyzing a vast and diverse cosmos. Know what intensity an object or a distant event shines opens the road to precisely calculating your distance based only on the intensity with which it shines in our sky. That is why these supernovas had been useful for calculating distances and with it the changes in the distance over time, that is to say the speed. The speed at which the objects of the cosmos move away from each other. Explosions of the most varied. The new study has revealed that supernovae associated with White dwarfs They are not in this group of regular cosmic events as we believed. Through its observations, the team found “multiple and exotic ways” in which white dwarfs could explode. These included collisions between two stars and star cannibalism in binary systems. “The diversity of ways in which white dwarfs can explode is much greater than it was previous And until years later ”´, pointed in a press release Kate Maguire, co -author of the study. 4,000 Supernovas. The finding was possible thanks to the use of tools capable of detecting very faint signals and the accumulation of a large amount of data for the sample. The team resorted to the data of the ZTF survey (Zwicky Transient Facity), From which they obtained information from a total of 4,000 supernovae, a sample, they explain, much greater than those previously compiled. “Thanks to the unique capacity of ZTF to scan the sky quickly and deeply, it has been possible Maguire added. The details of the study were recently published in a special number in the magazine Astronomy & Astrophysics. Dark energy. The finding is at the same time a problem and it is that if we lose one of the tools used to calculate the distances in the cosmos. In spite of this, it is great news since knowing that the outbreaks of white dwarf the one that moves away from us.

will pay for its Puretech engines and now for its failures with the adblue

by

Stellantis has lived two great controversies in recent years related to their engines or the systems that make them work. Controversies that have ended up exploding in recent months and that is forcing the company to expand its guarantees and give greater coverage to affected customers. We recently knew that Stellantis promised Expand the guarantee of your PureTech engines retroactively and that would assume the expenses of the Repairs between 2022 and 2024 as long as some conditions are met, such as being able to certify that maintenance has been passed correctly. The other front that the conglomerate has open is related to the failures in the adblue systems of its cars. Now, the company undertakes to expand special coverage for Peugeot, Citroën, DS Automobiles and Opel/Vauxhall cars with Euro 6 diesel engines. In the case of having paid this special coverage, now it will be the clients who can request that the money be reinstated. The problems with the adblue and the response of Stellantis In Europe, since 201 the standard has been applied Euro 6 To all the cars approved since then. This new emission regulations forced manufacturers to assemble SCR systems (selective catalytic reduction) to reduce NOX (nitrogen oxide) expelled to the atmosphere. He SCR system It is designed to break down part of the polluting gases in nitrogen and water vapor. It is, ultimately, a catalyst installed in the exhaust pipe. Said catalyst It works with Adbluea product in liquid format that combines water and urea (32.5%) that is injected into the catalyst. The heat produced by gases causes it to become ammonia and breaks down those same gases. To ensure that cars contaminated as much as possible, the European Union forced the manufacturers to include the impediment of starting the car if the deposit lacks adblue enough to guarantee its operation. If the tank is spent with the car running, it continues to work but once off, we will not be able to start it again. The problem that some Stellantis clients were found is that defective deposits were produced. If this failure was given, in some cases it was requested that The deposit will be filled Before time and the car was still working but, in others, the car understood that it lacked the liquid and, therefore, prevented the car from starting. The only solution to this problem went through the replacement of the Adblue tank, which could lead to an expense of about 1,000 euros. In December last year, The European Commission has already confirmed an agreement for which he forced Stellantis to compensate users as follows: 100% of the cost of the pieces in vehicles with up to 5 years and up to 150,000 kilometers. Between 30% and 90% of the cost of the pieces (depending on the mileage) of cars between 5 and 8 years. The cost of assumed labor will be 30 euros, unless the damage is recurring, in which case it will assume all the costs of the authorized workshop. The campaign began in Italy but now The special program to all of Europe is expandedincluding Spain. The cars that receive this guarantee are those manufactured between January 2014 and August 2020 when the adblue deposits that were set up until then in the diesel cars of Stellantis were changed. In addition, it is specified that customers who already repaired their vehicle from 2021 and were compensated at that time by Expanded coverage that have been applied so far by this problem, they will have the right to request an extension of the reimbursement money taking into account these new conditions. Those who wish, will have to request the expansion of coverage online using this link.
