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.

Front Suspension Ride Height Has Dropped: The front suspension ride height has dropped on one or both sides due to overload. This is caused by driving over obstacles (e.g. potholes) or an impact severe enough for the front spring strut damper to slip through the clamp of the steering knuckle.
