i took my car in because of the ABS, DSC and brake light on. they fixed it and all of a sudden the check engine light came on. i asked them and they said that there is probably a problem with the exhaust or something.
Mine has been coming on since October. 5 times now. Pursuing a lemon law case now.
I don't think they have a clue what's wrong but here is what has been done to mine:
10/17/02 replaced o2 sensor behind cat bank 1
11/15/02 dealer waiting for tech assistance
12/10/02 replaced o2 sensor before catalytic converter
12/27/02 reprgrammed DME
2/14/03 replaced camshafts and lifter carriers, reprogrammed DME, replaced mass airflow sensor
3/22/03 light came back on
3/25/03 dealer ran diagnostic check on it found DME code 226, E2 trimming, oxygen sensor behind cat bank 2 too great in rich range
3/28/03 BMW NA wants me to take it back on 4/15/03 and let them try and fix it again
3/31/03 I hire a lawyer to pursue a lemon law case and hopefully get a new car.
