I have a 05 Audi a3 1.9 diesel. I had the air con on yesterday. I knocked off the economy and had it blowing towards my face and windscreen. I didnt have a passenger. However when my husband get into the car today the temp was 28 on the drivers feet and 21 blowing towards the passengers face!!! This is not the first time this has happened. It is always on 28 drivers and 21 passenger. You might have gathered that I'm not technical minded so if anyone knows why this is happening and can describe to me in laymans terms I would be extremely grateful.

Thanks
