Hi all,
A couple of days ago I bought an old Audi TT purely for a toy.
It's done loads of miles but had cam belt/tensioners/water pump/pulleys etc all done within the last few weeks and goes like stink so I'm happy for my £1400
Anyway, my air con isn't working. I found a cheap re-gassing service on groupon and took it in. When I went back in the guy said it was fully gassed already but he vacced it out anyway and regassed it to the correct pressure and showed me all the printouts from his machine showing amount of gas removed and the amount of gas/oil/uv replaced. He said it's not kicking in and it is likely to be the pressure switch.
I got home and started reading up and found a load of useful info saying you can jumper out the four pin pressure switch to prove the system is working. I found my pressure switch and lo and behold it's actually a 3 pin variant and my trail of information dries up there.
The compressor isn't engaging, the clutch seems to spin freely. I'd just replace the pressure switch to try but I'm not even sure of the right part number (there seem to be four variations)!
Does anyone have any experience with VAG air con systems ? Any info, pointers, advice gratefully received.
Thanks,
malty
