Update on my post re leaking sump.
Week and a half after the service the computer was telling me to top up the oil, half a litre. So, concerned I took the car back to the stealers and after they had had a look, that took them an hour and a half, they informed me that it looks as though the turbo oil return pipes were leaking! They would like to have it for a couple of days to check it out. They have booked it in for two weeks time.
I then went to an independent Jag specialist. After just a couple of minutes having the car up on the lift they agreed it is the turbo oil return pipes that are leaking.
Both myself and the indy think the oil leaking from the turbo oil return pipes obviously ran down onto the sump case giving the impression that the sump gasket was leaking, a far easier fix than the turbo pipes. A costly miss diagnosis. It has left a very nasty taste. I am finding it hard to believe I am having these problems on a five year old, 33000 mile car that is lovingly cared for.
I had already written an email of complaint to the branch manager, with no reply, I have emailed quite a detailed account of the situation to Jaguar Customer Services and they have emailed back informing me they will be liaising with the dealer.
I have never had anything like these sort's of problems with any cars that I have owned over many years of driving, 54 years in fact. If I get no joy from Jaguar or the dealer there is a strong possibility I will go back to BMW or Mercedes.
