22 hours labour for £3k is about £136 an hour. Thats luxury car brand main dealer prices, so pretty expensive imho. I would be expecting an independent to be significantly cheaper than a main dealer, otherwise whats the point in using them ? You may also be able to find OEM quality parts for less too - look to independent part suppliers & specialists - Jaguar Parts, Jaguar Spares - JustJagsUK.com for example. Stick to quality manufacturers though, we don't really want crappy chinese parts on the car.
I did a little reading and the 4.0 engines appear to suffer failed tensioners that then cause the chain to go slack, the result of that is a correlation error between crank and cam. It seems the 5 litre engine can have the same issue, but it isn't as common.
What I do see though is owners reporting an engine fault on the dash (sometimes intermittently) rather than a failure to start.
Where I'm going with this is it could be a sensor fault - if any of the timing sensors are giving an implausible signal you could get a correlation fault - just like a stretched chain/failed tensioner. By now your garage should be able to prove that. It would seem strange that the car was running perfectly and now refuses to start due to a stretched chain/failed tensioner. If you had seen a engine fault code previously I'd be more inclined to agree..
With regards to a potential claim it doesn't matter what mileage you've done in it, you'd have to prove that the fault was present when the vehicle was sold and that the issue is beyond normal expected wear and tear.
Given that the car ran fine when purchased the counter argument is that the fault was not present at the time of sale. They could also argue that at 90-odd thousand miles a stretched chain/failed tensioner would be typical wear and tear. |
