Question about BMW Cars & Trucks
Hi Thomas, The problem could be related to burned valves, a leakage on the intake manifold, a defective airflow sensor, or a number of other problems. First disconnect the airflow sensor and start the vehicle and determine if the backfire is still there. If it behaves then that unit is defective. I suggest you have a diagnostic scan carried out to determine what is causing the problem on your BMW. Regards John
