Hi Mark, I had a chat with the garage owner, chap called Steve, didn't have time to ask about your specific problems but he would be happy to take your call and discuss the issues you have with your XJS, he's glad it's one of the older ones as he says there were many changes before Jaguar ceased production. His name is Steve, call him on 01684 592271 - he probably wouldn't recall me by name, just say you're from the J.O.C. and I've spoken to you mention I drive the green V8 S-Type (he's all about cars). Good luck, Dave
