What it covers
A service bulletin tells BMW technicians how to diagnose or fix a known issue. It is not a recall: a repair under a bulletin is normally paid by the owner unless the car is still under warranty or a warranty extension applies.
Due to an unfavorable operating point, primarily in the low-end torque range, an incorrect detection of amixture that is too rich could happen.
