Hello, I have the following problem with my BMW 645ci year 2004 with 95000 km. In the KALTEN condition especially now in the winter the transmission switches at constant speed, so at 80 up and down as it likes and often (not always) after about 3 min. the message Dynamic Drive fails. When I then drive the car warm and restart everything has disappeared. The transmission switches gently and the message is also gone. Has since already had experience or has an Ahn I’m asking for help.
