I had repeated checklight problems on my 2000 S-40. The code said it was a gas cap
problem, and the mechanic blamed it on the gas cap not being put on tight. The third time
it happened, I was much annoyed, and the service manager suggested trying a new gas cap.
He took one out of the parts room, and as he put it on he said it was a slightly different
design. It fixed the problem. I suspect Volvo had a reason for the design change.
