We took the car in because it the alarm system needed to be reset and the car would not start. They said that the electrical needed rewiring because rodents had eaten the wires??? Strange i have no rodents in the garage plus they installed some computer part the bill was $1400.00. Took the car home and it overheated it had no coolant. We took it to a test only for a smog check and the computer is not communicating. i called several times for a copy of the bill and they did not send it. I left several messages for the consultant and the service manager and nobody called back. I took my car to my BMW trusted mechanic and said that the electrical wiring has a problem. I am afraid to bring the car back to these people. Do not bring your vehicle to Center BMW Van Nuys.
