    I know, it's a right pain. They did change it to 14 in the B7 I believe. I tried a B7 module in my car and everything worked ok except for rear heated windscreen, so I guess it's a slightly different setup in the newer climate control models.

    Same as mine - 18c or 64f, and then it goes to Lo.
    When Lo is showing, I presume the air con (cold) unit comes on, without measuring the temp inside the car.

    Yes exactly and it doesn't take too long to get too cold, I generally have mine on 18 or Low and not always on Auto, sometimes I'll just have the fan on 1 bar, that seems to help a bit

    Sounds like there's a problem, it could just be gas, it could be the connector has corredded like it did on mine or it could be the compressor.

    Under the bonnet on the back left there are two a/c pipes, when your engine is on and a/c on low one should be freezing cold and the other warm, if not it's defo one of those above I would think

    There probably is, oddly it showed no faults when mine went, but someone else who's more clued up on the in's and out's of vag-com will be able to tell you, perhaps in the VCDS forum if not here.

    If your air con isnt working then the red econ light stop on and stops the compresser from working, you need vag com to read the fault code and hopfully its a pressure switch.



    Hope the people that took me DIE

    Am I right in thinking that's just if it's a gas/pressure issue? As I never had that happen on mine.

    Vagcom will detect most aircon fault codes, but it obviously won't tell you if it's low on gas! Chris it sounds like yours is probably 'a bit' low on gas, but not low enough to cause the compressor to switch off. It does this to protect itself as the gas supplies the lubrication, when the compressor isolates itself is when the ECON light comes on.

    The ECON light is usually either the high pressure switch or low on gas. If it's low on gas get it pressure tested before refilling as if there's a leak you need to sort that out first.

    I think all B6's only go as low as 18, (but maybe some very late ones go to 16...?) and the B7's go to 16. A B7 climate control can be retrofitted, but as mentioned requires a mod to keep the heated rear screen working, Woorlord can help you with this. The B6 aircon is just notoriously inefficient! For some reason an Audi 18 feels warmer than other manufacturers! Mine will blow lovely ice cold air when set to LO, but as mentioned it's a PITA as you have to turn AUTO off or the fan goes flat out - and then when eventually you get too cold and have to raise it 18 it blows hot air!

    At the end of the day though, it will keep you cool if it's working well

    That's good to know, wish I'd kept that B7 unit now, ah well

    It screws in the N/s of the condenser, its a pretty easy change and you shouldn't lose any gas in doing it:

    Just
    slide out the passenger headlight and it's there on the left, 2 spanners and it's off. No gas loss, but check to make sure the rad piece is lubricated , this means you've plenty of gas with oil still circulating.
