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.
N52T Alternator-Related Malfunctions: Overcharging or Undercharging. Many different complaints may arise from alternator-related malfunctions, due to charging sporadically or not charging at all.
