Leaving my kids swim team try outs and upon start-up get a message that DTC is not functioning and the DSC is operating only partially operational. I check the iDrive for check control messages and it says the same thing, so I press the DSC button and all the error messages clear. Thinking it is a software glitch, I drive off. As I pull on to the roadway, the car is now running rough and while I have the tranny in Sports mode, it will not shift out of S3 as I rev up to 3,500+ RPM. I limp along the interstate thinking "damn, I'm going to have to bring it in tomorrow morning". Thankfully the interstate stretch going home is short. As I drive down a busy street, this continues for a while until I finally hit a red light where I turn off the car for 10 seconds and restart. Now all is back to normal. Was all good this morning as well. Anyone experience anything like this? It's a 2008 550...

I had a similar problem a few months ago. It seemed like every other time I started up the car, it would drive for a while and then iDrive would show messages that the DTC wasn't working. After a few weeks of that, I finally got really fed up with it and took it to the dealership... they reinstalled the OS and it's been working well ever since.
Might wanna get an OS reinstall and see if that helps.

ks - almost sounds as if your car went into the "limp home mode"? Mine did this a while back and once I restarted it - all was fine....

It seem to happen not only with cars but also cell phones, digital TV's, laptops etc....

Anyone else long for the days when cars were repaired with TOOLS, instead of "software updates and reinstalls"????
