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.

Vehicle exhibits a slight acceleration delay when taking off from a MSA (automatic engine start-stop function) stop.
