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.
DELIVERY STOP - STARTER MOTOR: BMW AG has issued a Delivery Stop on a small number of Model Year 2020 BMW 3 Series that were produced between March 6 2020 and March 11 2020. A starter motor nut will need to be inspected and if necessary tightened to specifications.
