CEL on then off
Figured I would give me .2 cent on CEL light...Last night CEL came on took it this am to autozone to run diagonstic and came back with a P0015 code (camshaft). Later in the day got ready to take into dealer and CEL was off. Dealer said it was possibly due to cold weather and unless light was on not much they could do. On a side note he asked if car was still under warranty (which it is) he said to wait and not worry.

I just had the same thing happen on my 350E. CEL came on for a day and went off. I took it in to the dealer and they replaced the camshaft sensor under warranty. The computer will likely store the code, even if the light goes off. I'd deal with it now, perhaps at a different dealer, rather than wait for it to cause a real problem.
