My wife's 2009 X5 3.0 had a loose gas cap light come on and then the CEL. The code reads P0442 read at a local gas station. Would a BMW code reader be more specific about what the problem is?
The gas cap was replaced but the CEL is still on. The X5 runs fine but the CEL has been on a month now.
We are out of warranty and the doomed feeling of my first big repair bill is coming.
Has anyone had to deal with this on their own?
Thank you
