I have not heard of a way to look at the diagnostics on the XLR, unlike other Cadillacs that use a combination of buttons to bring up diagnostics.
First thing to check is that your gas cap is still fitting tightly. If it is, then I think you are in for another trip to the dealership. Sorry about your incident but it is good to hear that the XLR is back in one piece.
