    Hi, I'm a newbie to the forum and recently purchased a 2004 B6 S4. When i bought the car, the weather was a little chilly and therefore I didn't get round to testing the climate control fully. It seems to work fine when I need to warm the cabin on chilly mornings but now the weather has finally decided to warm up a touch I thought I'd try it to on the LO setting. The first time I tried it, it seemed to work fine and there was plenty of cold air blowing into the cabin. However I have noticed that it doesn't always seem to work. Yesterday I turned it to LO and there was still warm air pumping out of the vents. It would appear that its intermittent as to when it wants to work properly!! Has anyone else experienced a similar problem?? I'm hoping a simple re-gas may sort this!! Thanks in advance!!

    Get vcds (vagcom) Hooked up to it. To scan for any faults just to Be sure.

    also due to the age of the car it might just need a re-gas. Maybe take it to somewhere that does air-con to get them to have a quick look.

    turn car on, pop bonnet, see if air con rad fan is spinning. If it isnt then chances are it needs a regas.

    I'll check the fan first and see. Failing that I have found a local car electrical specialist that does free air-con checks and give them a whirl! Hopefully a re-gas with fix it! Thanks for the advice chaps!!

    I've just fired the car up and switched on the climate control on the LO setting and the fan does kick in. However there is still only warm air coming from the vents.

    No, even if I switch the Econ button to on it still doesn't make any difference. Just so as I'm not looking at the wrong radiator, can someone describe where the air-con rad and fan are on an S4? Thanks.

    You could have a flap motor stuck.
    Common problem.
    Try a search.
