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.
The Malfunction Indicator Lamp (MIL) light is on and the following fault code is stored in the DME: 1B8004 - EAC Sensor: Temperature - Engine coolant temperature radiator outlet comparison to each other implausible DME software calibration error for EAC sensor diagnostics.
