I have acquired a 2010 Jaguar XF 3L DIESEL, it is a non starter and has multiple faults on it. I have had a mobile vehicle technician round to do a full diagnostic check (which he did) , but due to the amount of faults he said he wouldn't know where to start with getting it back on the road. I have been given the name of an auto electrician but i've also been given the name of an independent Jag specialist (by another mechanic) who he said he uses when 'his software won't go far enough into the system'. That mechanic says it looks like it's been 'spiked' either an electrical surge or jump started incorrectly. So my question is what would people do? Bearing in mind wherever it goes it will need transporting so will cost £££, do I get the auto electrician round? Or do I plump for getting it transported to a Indy Jag specialist? In the hopes they can narrow it down to a couple of ECU'S that I can get off ebay?

I think in your position, i would find someone selling parts from a complete car that was running and is being broken due to terminal rot, accident damage or similar.

Buy the complete set of ECU, transponder, fob and any others you might need to fit a set and get it running. I'm relatively new to Jags so don't know which ones exactly you'll need, on a Rover 800 i'd say ECU, CCU, reciever, transponder key and fob and know you'd be good to go.

I'm sure someone with a bit more product knowledge on Jags will be able to give you chapter and verse on which modules/ECUs you'll need exactly.

Also have you tried a reset on your car to see if that resolves the problem? I know a neighbour bought a Ford Kuga that had been spiked and it cost him near £2k for diagnostics and secondhand ECUs......
