It sounds like a lowhum that last for only a few seconds. This can occur with the engine operating or may be heard for up to one hour after engine shut down.

may be heard.

The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors.

Software in potentially affected vehicles may not recognize the removal of the digital key (Key Card or mobile phone) from the wireless charging tray, and thereby not meeting a federal requirement. On February 17, 2023 , the Delivery Stop was upgraded to a Non-Compliance Recall (see SI B84 01 23 ). SIB84 01 23 outlined a procedure for vehicles at that time which were- a) in BMW center inventory b) already delivered to customers This new SI B84 03 23 addresses vehicles which were in BMW center inventory or at the Vehicle Distribution Center (VDC) at that time. Those vehicles had the Key Card removed and were able to be retailed to the customer Such vehicles now need to return to the center to receive a new Key Card and updated programming. Please note that vehicles which were already in customer hands will be addressed by an update to SI B8401 23

highway driving), there may be a temporary, slightly noticeable increase in steering forces when steering out of the steering wheel center position. This minimally noticeable increase in steering forces is perceived as a slight, brief resistance. After overcoming this brief resistance when steering out of the steering wheel center position, no permanent increase in steering forces is noticeable.

following customer complaints: KAFAS camera system deactivates itself, due to system restrictions that are not clear to the customer KAFAS camera system cannot be activated due to system restrictions that are not clear to the customer Road signs are sporadically not detected.

This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle discharged battery complaints.
