Disableing backfire on cold start
For the third time in apx 20 months an extremely loud backfire occurs on start and the car is disabled and must be hauled to the BMW of Austin service dept. The explosion was so loud it brought my neighbor out of his house to investigate.
The intake manifold must be replaced. The stated cause is " fault air mass meter caused engine to run lean causing a lean misfire in the intake....."
Has anyone had similar problem?
