Hopefully this business has come to a conclusion (but I have reservations).
The Jag place couldn't fix the air-con on Wednesday. They said they couldn't get the last 20% of the gas to charge and that the machine was saying my car's air-con system was contaminated. The gave me the car back without charging anything and said they'd see if there was a problem with their machine.
Their 'health check' said the car had a broken spring coil (£1150+), required wheel bearings (£1140+), new discs (they were new two years/10k miles ago) (£290 front, ££340+ rear). All in all £3500+ of work (for a car they probably wouldn't offer me £2000 for in a trade-in).
They also advised of a chip in the windscreen. Couldn't they have noticed it was already sealed by Autoglass?
"Dents and scratches around car" - geez, did they use a magnifying glass to find them? The car is a 55-plate and has over 187,000 miles on the clock. I know every scratch and dent on the car and they are hardly visible. Anyone glancing at the car would think it is in fantastic condition for its age never mind its mileage.
Anyway, I stopped off at the garage across the road and showed them the health check report. They said they'd been genning up about air-con (since they're getting the machinery fitted soon) and have been told that it is a cash cow. Apparently saying the system is contaminated is the open door to big money. They can fix the coil spring for about £75 all-in, by the way.
Some good news, though.
Jaguar phoned me back. There was a problem with their machine and they could do my car on Friday so I took it down yesterday. They recharged it, gave me £20 off for having to come back, and washed the car. That seems fair enough.
My reservation is that it was so chilly up here yesterday it's hard to tell if the air-con is working as it wouldn't kick in, even taking the temp down to minimum (<17C) as it was 13C outside and dropping.
