Had this 30C1 error code pop up twice now. Several month ago I came to a stop on a steep decline. I shut the car off and upon restarting all was good. Then early this week, while checking out my differential problem, the Indie Tech reported that the 30C1 error popped up while they were test driving the car. Car is a 2011 Z4 3.0i N52 engine. Any suggestion as to what to check?
Btw, oil and filter were changed a month ago by the BMW dealer.
