Hi guys,
today, while driving on snowy roads in Warsaw, Poland, Europe, My beast displayed me 4 messages as in the title. I called my sales guy at BMW, he asked me stop and to call the assistance (tow service) and he will call me back.
20 minutes later, they towed my car, he called me, they have a message in my keys : Low break pressure, breaks faulty and rear diff fully blocked.....
BMW showed up with a E91 318d and asked me to leave my M5 and use the 318, they will call me on tuesday.. i will keep you informed
Take care

Hopefully it is only a minor software issue.

to close the issue: bmw replaced a faulty rpm sensor on the wheel. that sensor reported that the wheel is not turning while it was.

The faulty rpm sensor also caused the brake and rear differential error codes?

It wouldn't surprise me. It's all related, and all controlled by perceived wheels speeds and driver input.

a crucial component for the driveshaft. It reports rotation speed to the central units. That info is crucial to many other components (brakes, differential, MDM, traction control.....)
