Took my 750LI 2006 to the dealership for a "kick" in the transmission while shifting. They recommended and did a software update. Took it for a test drive and within the 1st few minutes, I noticed that the kick has gotten rougher then the warning light came on indicating a fault in the transmission & went in a safe mode. Took it back in & after running a scan, they said it needed a new transmission. I asked them to clear the fault code, and drove off. Surprisingly the car ran normal for the next few days which compelled me to consult other technicians. Some believe it could be a sensor problem misreading data which caused it to go in safe mode. nothing wrong with Transmission. BMW NO ethics!
