DenisO Posted November 18, 2005 Report Share Posted November 18, 2005 Took my recent purchase (98 A4 Avant 2.4SE Auto) to the garage this moring for a cambelt change and general check over. Noticed that the frost symbol on the CC display was not on. I tend to run my CC year round to keep everything pucker. When pressed it only lit up for the time I was pressing. Now it was very cold down here in Kent today with the display showing 0.5 C and the garage says that Audi's CC will not allow the compresor to come on below certain temperatures. Is this correct and if so, how do I run the system during the winter. Link to comment Share on other sites More sharing options...
CH_Peter Posted November 18, 2005 Report Share Posted November 18, 2005 Don't think that's right. The compressor also takes moisture out the air, allowing you to de-mist that bit faster. I smell stealer porky pies. Link to comment Share on other sites More sharing options...

s4_sat Posted November 18, 2005 Report Share Posted November 18, 2005 mine doesn't come on either, i think its to prevent the pipework freezing during the cold weather. Link to comment Share on other sites More sharing options...

Durrsaku Posted November 18, 2005 Report Share Posted November 18, 2005 Ouch that hurts. Only said it cos mine has developed a leak and gas has gone to be reunited with it's creator. But hey who needs cold aircon in these temp. Link to comment Share on other sites More sharing options...
lottiefox Posted November 18, 2005 Report Share Posted November 18, 2005 Durrsaku I am sorry.... I didn't know you were leaking gas!!! Climate vastly overrated. Put windows down and drink in the fresh air. Link to comment Share on other sites More sharing options...

chrisan Posted November 18, 2005 Report Share Posted November 18, 2005 [ QUOTE ] ...the garage says that Audi's CC will not allow the compresor to come on below certain temperatures. [/ QUOTE ] This is correct. Due to the ambient air temperature, the condenser would become so cold it would freeze. Judging by the posts, some ppl's CC don't seem to show a warning, but below a certain temp, the air con pump will deactivate. You can proove this by popping your CC into recirculate mode in sub-zero temperatures. Before you know it, the car will mist up inside (like it did for me this morning) - because there will be no dehumidifing effect since the air-con will probably be deactivated.

Ari Posted November 19, 2005 Report Share Posted November 19, 2005 Yes indeedy. The new systems don't have the snowflake symbol on the CC panel to indicate compressor running so you wouldn't know it was off. The older ones did (note the original question was about a '98 car). My Audi A3's ('97 and 2000) both had the snowflake when air con on, and both shut the compressor off (thus snowflake went off) in very cold weather. If you pressed the button the flake would come on for a second and go straight off. All perfectly normal and correct, nothing to worry about.

[/ QUOTE ] Just run it as normal, the car will shut off the compressor when temp drops enough. And you aren't going to want chilled air when it's that cold, trust me! Compressor (and snowflake) will come back on when it warms up. If it doesn't just press "Auto". Link to comment Share on other sites More sharing options...

DenisO Posted November 20, 2005 Author Report Share Posted November 20, 2005 OK, so it is clear that the compressor doesn't run under a certain temp but I have always believed that, even in winter, you should run the system for about 1/2 hour per week to keep all the seals lubricated. How do you do that if it's designed not to work below, say 2 degrees. I guess that shouldn't be too much of a problem in the UK as we don't often get months of such cold temps but in Scandanavian countries it must be an issue; unless they are designed differently for other market.

chrisan Posted November 20, 2005 Report Share Posted November 20, 2005 I guess there will be some subtle design changes for different cliamates. As you say, in the UK we rarely have long periods of 24 hour subzero conditions. Link to comment Share on other sites More sharing options...
