Turn key to on, Floor accelerator 5 times within 5 seconds, count the "check engine" light flashes. It will flash out the code that the on-board computer has in it, and possibly the problem. With my 535i - Mass airflow sensor. You'll have to search and look up the meaning of the codes. For example: 1 flash, short pause, 4 flashes, short pause, 3 flashes, short pause, 1 flash, LONG pause would be trouble code; 1431 (not an actual code, by the way...) Good luck ;)
