One problem related to check engine light on has been reported for the 2001 BMW Z3. The most recently reported issues are listed below.
I have a Z3 2001. The car keeps stalls while driving. The BMW service department in columbus ohio has been unable determine the problem and are unable to repair it. They said it was a fuel pump, then said it was the idle control valve then said they still do not know what is wrong with it. . They've had it on and off since may 6. (about one month). The car is unsafe to drive while stalling without warning. The engine light does not come on after the car stalls. I do not feel safe driving a car that stalls.
