Lately I've seen a lot of post asking for help with a CEL or air/fuel ratio problem. If you don't know it is recomended by BMW that the O2 sensor be replaced every 100,000 miles. If you don't know when it was last done replace it. And since it only needs to be replaced every 100,000 miles replace it with a good BOSCH one, don't go cheep and get a universal one they never last long or work as well as the OEM replacement BOSCH ones do.
