I'm looking for advice. I've enjoyed my XF (MY2016) for over 5 years now, almost trouble freely. Sadly, the first potentially expensive fault has reared its ugly head, in that the air conditioning has stopped working. The local main dealer has offered to gas it up, and if that doesn't work subtract the cost of the gas-up from the total cost of replacing the compressor. If it is the latter, he will charge about £1000. On the other hand, the independent Jag specialist tells me that re-pressurizing the system will just waste the gas, and in his experience the compressor will have to be changed. He will charge £700. I could take the risk, and have the system re-gassed (~£200) but if that doesn't work I am stuck with the main dealer carrying out the more expensive work. What does the team think?
