I have a 2014 Sportbrake 2.2, bought in March 2018 and noticed a previous service sheet mentioning the diff pinion oil seal. Took it for service at a local Jaguar specialist near Cambridge and asked them to also check the diff. They told me it was fine. Three thousand miles later, I am driving through Germany and the diff becomes loud. When I manage to leave the autobahn at the nearest exit the thing is seriously hot, like smoking. I have returned home and am awaiting the quote for "a new back axle". My first Jaguar, 75k on the clock, 4 months of ownership. This looks like a big mistake. Does anyone know what this should cost to fix in the UK, or can a reasonably competent owner do it? I can have it fixed in Germany or repatriate the car unrepaired since I have insurance for the transport at least, so I need to make a decision.
