I had the same problem some years back. The new Jaguar diff is slightly different and required the replacement of so many parts the cost was about 3.5k and that was 5-6 years ago.
I got a used diff from a breakers ~300 and a garage charged me 150 to fit it.
At the time there were lots of people with noisy diffs and it seemed common on 120k mileage XFs of that year
Can anyone help, my 2016 2.0 diesel oil light came on, then 200yds later it went into limp home mode and another 200yds the engine died and has seized.
Does anyone have a complete engine I could purchase or know someone who can be trusted to rebuild mine.
