Any had experience of the air-con de-gassing over a period of time (nothing under search, apart from my previous bleatings)

Every 10k (3months) and get the noise of a coffee perculator and the air con gives up. It's been in 3 times, they've put dye in it but can't trace any leaks. It does make a sh1t load of excess water (far more than the other one on the fleet) when parked. I'm guessing its venting out and creating the condensed water where the excess moisture bleeds away from, because it's not appearing within the cabin.

Just get fed up taking it in for the same thing...wasted day...Courtesy car woes, not the Bl00dy Beetle again!..."Anything else sir?" NO JUST FIX THE THING IT KEEPS COMING IN FOR!!!!!!!!!!!!

Go to another dealer.

This one is clearly incapable of finding what is obviously a leak otherwise the gas/oil charge wouldn't be disappearing in just 3 months.

Moreover, as the gas disappears, so does the oil suspended in it which lubricates everything so, probably just out of warranty!, you'll be replacing the compressor and so on.

Beetle courtesy car - some VW luxury vehicle status - wonder if Phaeton drivers get shafted as much (apart from greater depreciation)

Socks, goes against the grain, I know, but it might be worth it in the long term to go to an aircon specialist.

Took SWMBO's 5 yr old Merc to one in April because of "percolator" noise. Spent ?60 but took an hour - a full 20 mins evacuating the system to remove every trace of water vapour - very necessary apparently. Then very careful to add exactly the correct volume of R134a. I can't see your typical stealer having either the kit or a tech with the expertise.

Since your stealer can't fix it you would be justified in seeking to get the bill paid by them.

the dealer will have access to the trouble shooting procedures from the A/C OEM - these will take a lot of time to go through so they probably missed loads of checks and went with the obvious

Q. Are you seeing 'water' under the car? If so, then this isn't de-gassing
Q. If water, and its excessive, then this could be evaporator freeze up (which is actually one side effect of over gassing amongst others)

Quick test you can do - turn the A/C off and run the car for a few days - do you get the same problem?

I can give you/dealer a full check list of tests to confirm the A/C fault if you need it

Gents,

Thanks for your advice. Armed with this info I will approach the grudge again. Coincidently, I drove past an air-con specialist the other day and thought that may be an alternative route around the problem, but as it's warranty I'm loathed to part with cash when it should be fixed by VW (especially when I'm efficient enough to combine the visits with a service)

Re Kaine's Q's - I'm getting a great deal of water, but also the noise of a partly vacant system, so I don't know really. I might take the noobsters advice and vote with my feet.

Well, she's back from a couple of days in the grudge and it would seem like the leak has been fixed. Apparently it ws a leak around the air con compressor unit. The offending area could only be inspected by removing the front bumper/bodywork.

Hopefully that's the end of it.

Yep!

Could be going in again as I've noticed today that I don't think they have fitted the offside headlight back in it's mounts correctly. Seems to be loose and slightly misaligned with the wing panel gap.

Bit of daylight at the weekend and I think I will try and sort it out myself!

If the headlight unit is loose, put some tape on it to make sure it doesn't come out under heavy braking until you get it fixed.

Had a similar problem with my Yreg last year at 7k miles. Informed it was leaking high pressure switch on aircon. Am suspicious problem is re-occuring so will have to endure another shed on wheels (touran) if they have to do what was threatened last time and take whole of aircon unit out (3 days shop to do this apparently). Overall very disappointed with Treg from reliability viewpoint so far(Disco 3 far more reliable), which is a shame, as rest of vehicle is superb.
