I apologize for the lack of a response to your earlier post, but that is bad if you can smell fumes in the car.

I do not know specifically what that code means, does it say in your owners manual what those numbers mean? Otherwise take the car to the dealership or call jaguar and they will advise you on what to do. Either way you'll probably end up at the dealership, they will run a diagnostic test on your car.

Congrats on the new car, btw...make sure you find a good friendly jaguar dealership they will be needed on your xk8. I know some dealerships are very good, but we go to imperial motors and they are actually cheaper than any mechanic, so dealerships can be good
