I have a XF 3.0 diesel V6 luxury model 2011. it's near to 80k on the clock so it's in tomorrow at my local Jag dealer for the cam belt change that's £625 they inform me it's 101k or 10 years prefer to change now!! Asked for water pump and fuel pump belt at same time their getting back to me on cost for parts! could get cam belt done for £450 but have chosen to stay with the dealer on this job their 2 year guarantee on the work/parts done it for me plus they've done other jobs and all has been excellent.
