my BMW broke too. one of the turbo fail and rejected all in the motor also one flap goes to the motor. I had finish to pay the leasing after 3 years and voilà you get nothing, just lost 15000$. The car had 140'000km, a BMW 123d. A lot of serie 1 get the same problem. I had to wait and town the car to my country (800km), lost 3 days of vacation. I hate car now and all the service that goes around.
