BMW service bulletin · NHTSA ID 10161581 · May 2019 · also written SI B84 07 19, B840719

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.

BLUETOOTH CONNECTION IS LOST DURING A PHONE CALL. During an active call the call audio autonomously switches from the vehicle hands-free system to the phone.
