I likely did not communicate clearly enough: it is tricky because of organizational reasons, not technical. There are many trade-offs that have to be made and it involves different business units with their own targets and incentives. To take a few examples from the article with likely causes (note I don't work for BMW, so this is pure speculation based on my own experience): > BMW has over-engineered the diagnostic procedure to such a level that even their own technicians often do not know the correct replacement process. The ECU, diagnostic procedures and service methods are being developed by a different org-units. One is engineering, which works towards their own development use cases. They might develop the on-board diagnostic interfaces. The service unit develops their own tester and have to develop their own procedures. Engineering is usually late with providing real hardware & software samples, let alone a fully integrated car. The service unit might only get a working test car very late in the process and discover that the procedure is super complicated. …

> BMW refuses to provide training access for ISTA usage Refusing access to training isn't a BoM issue by any means. Neither is a repair process that's so error prone that it can do even more damage to the car. We are surrounded by evidence that manufacturers in every field are taking decisions that are hostile towards their customers in the chase for profits. With the rise of EVs with far fewer moving parts needing constant maintenance, the manufacturers had to shift to different revenue streams, like killing repairability and locking everything behind manufacturer approval. This is a professional shop voicing the complaints, not a random guy trying to do a fix on the side of the road. Imagine someone told you they work for Apple and the reason everything is soldered, glued, stacked in a way it will never survive disassembly, and every bit of software and hardware in the device needs the…

Thanks for your comment. It looks to me that most of the people who work in engineering area express some form of understanding or give the benefit of the doubt to the situation while people from outside the field borderline call for malice in the side of BMW. I think both are right. Engineering a modern car is really complex as you pointed out but the customer also has the right to say, "well that is what you are paid for". In the end the customer can just go to the next car brand. I own a relatively recent BMW but it is only a mild hybrid diesel (4 year old M340D) and before I even received the car, they changed the whole engine and did not release the car until that was executed. That was done by the dealer, and i never knew what was the reason. On the flip side of modern car engineering I once had a check engine light called the dealer and with authorization prompts on my side they w…

But that’s a very long way to say that yes, BMW is to blame for making something that’s hard to repair and doesn’t do anything about it because it makes them money. Other companies got it far better so your explanation is superficial. When a system “malfunctions” only to the benefit of one side it’s not “an issue” as much as design. Why don’t you run the same careful reasoning against any hostile action from any big tech company and see how it sounds? All the actions of Microsoft, OpenAI, Google, Meta, Amazon are just the result of unfortunate misalignment between teams. If a flipped coin always lands how the person flipping wants it to land, it’s loaded, not misalignment between hand and coin. I’ve seen how the sausage is made in corporations with more money and higher stakes than BMW. Once you get off the ground and see more of the bigger picture, you can’t unsee the hostile decisions …
