Accessing our car’s mechanics has become increasingly complicated. BMW has thought of complicating it even more
Do-it-yourself repairability of a vehicle is something that Over the years it has gotten worse. while the systems have become increasingly complicated. Therefore, it is not surprising that multiple manufacturers have chosen to design specific tools to access sensitive parts of the vehicle. In the case of BMW, a patent recently discovered Meanwhile, CarBuzz could make things even more complicated for those who want to have access to certain parts of your car. And the patent shows some screws with heads designed in the shape of the brand logo that require specific tools for handling. What is this about? The patent from BMW describes four different types of custom screw heads that replicate the brand’s circular emblem, divided into four quadrants. Two of these sections are recessed to accommodate the screwdriver, while the other two remain flat or raised. The design of this type of specific screws means that they cannot be manipulated with conventional tools such as Torx, hexagonal or Phillips, but rather requires parts manufactured specifically for BMW. Why BMW says it does. As the patent itself explains, the objective is “to prevent the screw from being loosened or tightened using common drive structures, for example, by unauthorized persons.” The company proposes its use in structural and semi-structural applications, such as seat anchors or joints between the passenger compartment and the supporting structure of the body. The intention is that these screws can be used in visible areas, since if we judge these screws from an aesthetic point of view, the truth is that molar is cool. The problem for workshops and owners. On the other hand, and addressing the central problem behind this decision, this would turn even the most basic maintenance tasks into mandatory visits to the official dealer or, at best, would force independent workshops to purchase exclusive BMW tools. Something that, on the other hand, is not so strange if we take a look at the history of many of the largest automobile groups. Just like account In the middle, working with a two-point system and the decorative ring taking up much of the surface of the screw would increase the risk of breaking the tools, especially in applications that require very hard fastening. It’s not the first time. German manufacturers have a long tradition of using specialized fasteners. Just like points out In the middle, Volkswagen, Mercedes-Benz and BMW routinely use triple-square, oversized Torx or even E-Torx screws, which force mechanics to have specific tool sets. Against the current. The curious thing about it all is that this patent openly contrasts with the direction that other manufacturers are taking. Mercedes-Benz for example, its main rival, advertisement that would work on redesigning its future vehicles to facilitate repairs. An example of this is their decision to replace the glue with screws in the headlights to simplify their replacement. Just a piece of paper, for now. The patent was filed on June 7, 2024 and was made public on December 11, 2025. However, it is worth remembering that manufacturers register numerous patents that never materialize in series models. There is no confirmation that BMW will actually implement this system in its production vehicles. For now, this is only technical documentation. A general trend. Regardless of whether these specific screws are manufactured or not, the patent is yet another example of the progressive distancing of owners from the mechanics of their vehicles. With electrification and greater technological complexity, drivers they increasingly depend on specialized workshops for any intervention. It should also be noted that very few owners fix or modify their car on their own. Perhaps precisely because the systems have become increasingly more complicated to access.
