AWD, DSC, ABS, and EMERG EBV
Yes, they all failed at once. I'm getting this error in iDrive on my E92 335xi. After googling for the error I only found a couple of hits for E60s that have had similar problems.
In those cases the sunroof drain system clogged up, causing a water buildup that shorted or caused corrosion in a couple of vital circuits located underneath the passenger seat. In my case I'm also hearing a clicking/grinding noise coming from about one foot behind the passenger side wheel well which makes me think it's not a water buildup issue, but something mechanical. Any ideas? Has anyone accidentally the whole drivetrain?
