BMW 3 Series Diesel 2010: malfunction of the seatbelt reminder, illuminated airbag warning light and stored system error

Hi, thanks for your reply. It's good to know that I'm not alone with this problem. May I ask how expensive the repair was for you? And have there been any other problems with your BMW since then?

Hey, of course you can ask! So, the whole thing with the belt ring cost me €455. The specialist found that the belt ring was defective and fixed it himself. It wasn't exactly cheap, but since then the thing has been running like clockwork again, no further problems since the workshop visit. Hope this helps you and hopefully your BMW will be running smoothly again soon!

Hi, this is really helpful. I am actually relieved to know the price. It seems expensive, but if it's done well and the problem is solved permanently, then I'd rather pay more for once. Thanks for your help and keep driving your BMW!

Hello everyone, I had similar problems with my BMW 3 Series Diesel. My seatbelt reminder also stopped working and the airbag warning light came on. This may actually be related, as the seatbelt reminder and the airbag system are linked. My garage first carried out a diagnosis to identify the exact fault in the system. It turned out that the seatbelt reminder was faulty and this also indicated a fault in the airbag system. The workshop replaced the seatbelt reminder and reset the fault codes in the system. After that, both the seatbelt reminder and the airbag system worked perfectly again.
