Hi, I drive a E90 320i. I experienced this twice in the past 3 weeks. The first time after driving, I reverse the car to park. As I engage the gear in Park, the engine sputtered then died. I had no problems firing up the engine again. The second time, my engine nearly died after I engaged Park. The rev dropped momentarily then went back to normal idling speed. I just sent in my car for 1st service before CNY. Anyone knows what the issue could be? I only pump Esso 98. Thanks.
