BMW service bulletin · NHTSA ID 10240266 · Jul 2023

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.

SPL Parts, Inc. manufacturers and distributes aftermarket lower control arms for dedicated competition vehicles and "track day" cars some of which may be used on both track and highway.
