I am the proud owner of a 2004 BMW Z-4, 3.0i with only 42K miles.My nightmare started when the transmission died and had the car taken to Bavarian Rennsport. After a new transmission from BMW we thought that all is well and on our way, two weeks later car died transmission light on, car will not move, burned out module,which was replaced,the car only went a short distance shuts down again. Sent car to BMW diagnostic they said burned out dash board need replaced at a cost of thousands. Shawn the owner said that cant be, and he will find the cause, they spent thousand of their dollars to figure out what was the cause.A burned out door sensor that told the transmission the doors are open and the car should go into park mode, if you keep driving you rip up the transmission.NO ONE COULD FIND THIS CAUSE THEY DID. What was my cost I paid for the module, they absorbed the rest. What a stand up company, no other place to take your BMW.
