Hi Keith, is this the first time you've had to do anything done to the aircon? Just wondering because mines ok at the moment but it is an 03 model.

Love to see it Brian if you can work the picture thingy out lol. Don't see many around these days barring club meets. Credit to you bud.

Hi Brian, the very best of luck with the treatment bud.

Yeah, you're probably right in the way that Rolls Royce wont allow a any one to see one broken down, Jaguar don't want anything to be viewed coming from underneath their cars. I'll go with that Peter.

oooooo, drophead or hard top is it a converted TR7 like Grinnall used to do or a proper works one? I had an Inca Yellow hard top I let Grinnall loose on fantastically awesome and scary in equal measure.

Not 100% sure but I thought you should get a puddle under the car every now and then as it discharges the condensed water. Have I got that wrong?

Wow, that's really interesting dude, its a shame then that I'm non too computer literate. I don't think that I would have the dangly bits to try should a feat though.

Graham, excuse my ignorance but what is a Mongoose (apart from the small African snake killing mammal) and where would one procure such equipment/software?

Blimey Graham, shame you're so far away, I'd have dropped round this weekend!! :D

Just done a quick search Phil, basically if you have a thermostat that is stuck in the 'closed' position this causes the car to overheat, if its stuck in the 'open' position the water keeps circulating building up very little heat causing no heat out put to the heater matrix. So, when you first start your car the stat is in the closed position allowing the engine and cooling system to reach optimum temperature for running efficiency, when this temperature is reached it then opens allowing you then to use your heating in the cabin. I think this makes more sense and that the cause of your issue is still the thermostat in my book. As for how to change it, a Haynes manual, youtube search or similar should be out there somewhere bud.

aye up Phildog, don't get down on your grammar dude, we are all here to help and the benefit of our experiences. More importantly lets try and get the issue sorted. As far as I am aware a regassing of the air con unit only affects the air conditioning ie the cooling system. If you are not experiencing overheating then the problem could be an electrical one as this controls the mechanical 'flaps' that, if faulty could be permanently in the shut off position, thereby inhibiting the flow of warm air into the cabin. I had a similar problem with a Fiat Tipo my daughter had, the control had broken and the car was freezing through one winter I remember, I went straight to the heater matrix and changed that but it made no difference.

Hi Phil. just reading your post and in particular your 'big' problem, you say there is no water in the lower hose, if this is the one that feeds the heater matrix then I think it would be safe to assume something is blocked or water is unable to get there. It is unusual that you are not reporting over heating problem as this would point to the thermostat. Are you sure that the water is circulating, holding one of the pipes and revving the engine you should feel a surge or increased pressure on the wall of the tube, this would therefore indicate that the pump is working ok. I would think that an 05 car would have at some point had the coolant replaced, therefore I can't really see it being a blockage or an air lock as you would hear bubbling & gurgling noises. I would start in the cheapest and easiest place, the thermostat bud.

No problem Mike.

Don't think I did the link right Mike, this is the website www.thelurch.com just follow the link on the right hand side to 'ZF Gearbox Lurch'

You might have already seen this Mike, but have a look here. http://the lurch.com/tsbs.htm It does mention a surging reported on a 4.2, TBS S307-14.

I thought it very reasonable too Peter, hence booking it in for our summer shut down in August. Andy also mentioned that it is the torque converter making the noise but it is not detrimental to the running of the car.

Just a note on some follow up info I have gained on this issue over the weekend. Having spoken to my local independent Jaguar specialist (Andy), he states that this issue solely affects the 3.0L models and in 99.9% of cases a reprogram of the Transmission Control Module cures this irritant. The work costs £65 + vat.

I always thought that Aston Martin got the balance of beauty and aggressiveness (if that's a word) just right, but Jaguar are really pushing for the crown these days.

Hi Keith, yes it is a little vague and based on a summations of my own after reading the hand book. Section 3-18 Before Driving section does state that the drivers seat should move on entry/exit, but then you also have the memory function (optional extra) for the seat, pedal and wing mirrors. It does seem a little strange that you would have two systems doing the same thing ie moving the seating position on entry/exit.

Beautiful styling, reminiscent of the old D Type racer.

You've just hit the nail on the head Peter, it would seem that, as with my car, the memory function setting that controls the steering wheel, seat, pedals and rear view mirror (if you were to have all these options installed) isn't fitted, ergo the steering column is all that adjusts on entry/exit. If you have the memory setting option installed then you get control of all the above on entry/exit. Hope this fits everyone's scenario's.

My steering wheel moves on entry/exit but my seat doesn't, initially I though it didn't because I have the seat near its limit anyway but on moving the seat forward and trying again it still didn't move.
