BMW service bulletin · NHTSA ID 10162396 · Jul 2019
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 / N55 with 8HP45: Delay in Engine Response. A customer may complain of a delay in engine response after decelerating at low road speeds and then reaccelerating. This can occur when the transmission remains in a high gear due to a delay in the transmission downshifting.
