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.
VOLUNTARY EMISSIONS RECALL CAMPAIGN 16E-A04: DME - OBD. The DME software calibration for exhaust gas recirculation (EGR) on board diagnosis (OBD) may not function correctly.
