| Approaching an intersection in my 2005 545 six speed, when the doors unlocked, the flashers activated and the iDrive screen frantically announced I'd had an accident and tried to send my location to BMW. I switched off the flashers and carried on driving. Now,every time I start the car, I get this ominous message on my iDrive screen "Fault in passenger restraint system affecting air bag, seat tensioners or belt force limiter".
Through all this the car has run just fine. I called my BMW Service Center and they say it's a software glitch and to bring the car in for a software update which takes 5,000 hours (or seems to); actually it's an all day affair.
Anyone else have this problem? If so, what was the cause? Also, after the iDrive tried to call BMW, it announced the call had failed. What does that mean? |
