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.

When charging the vehicle with an Occasional Use Charger (OUC) after previously using a Wallbox charger,the selected charging current might not be displayed correctly in the instrument cluster.
