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.

SITUATION BMW AG is conducting a Voluntary Emissions Recall (effective April 23, 2021) on a certain Model Year 2020 - 2021 BMW vehicles that were produced between August 13, 2019 and December 11, 2020.
