SIB 12 09 17: Control module rough running
Control module rough running on B38 engines (2014–2017); BMW released a software update.
BMW service bulletin · NHTSA ID 10149228 · May 2017 · also written SI B12 09 17, B120917
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.
SERVICE ACTION: PROGRAM CONTROL UNITS. The HV system is being shut off without a request from the driver. Erroneous fault memories can lead to unnecessary MIL activation. After starting the vehicle, the displayed electric range quickly reduces to an implausible level.
