Nick,
Can you please explain what 'air con machine' you hooked your A3 up to?
My 2010 A3 (6 months old) with climate control suffers from the same problem as everyone else's on this thread - cool, but not as cold as I believe it should be.
You knew what i meant.
I do more than those mphs as alot on here know!!! lol
Which of the two air circulation buttons is the one to use to stop hot air being taken from the outside? guessing the Auto one, but not sure as I havent really used those buttons
odd ... when on low its colder!
BINGO!
As I said, it's counter-intuitive, but THIS is how we deal with it here. Running the fan too fast makes the interior noisier, makes the A/C run hotter, and wears things out faster...
...to say nothing about messing up my fabulously-coiffured 'do'!!!
As for "wet-dog" smelling A/C, this happens if the condensate drain gets blocked or obstructed, but ALSO if you turn off the A/C by switching off the fan, or similarly by stopping the car with the A/C running.
What happens is that the condensation on the chilling coil is never dried off, so it just sits there for a long time and pools up, allowing mould and bacteria to multiply... Just like leaving a wet towel in a plastic bag for any length of time. (Which I used to sometimes do when I had swimming class at school, and forgot to take my towel home!)
The way to prevent this is to ALWAYS switch off the A/C using the switch, but LEAVE THE VENTILATION FAN RUNNING. -In this way, the condensation is evaporated into the vehicle cabin. -If you have the A/C on just before you pull in to home for the evening, SWITCH OFF the A/C about a minute before you pull into the driveway, but LEAVE THE VENTILATION FAN RUNNING. That way the water never just sits in a foul, stinky puddle overnight.
It happens on every car with A/C, though some are more susceptible than others, depebding on factors like how high up the coil is, and how well 'aired' (ventilated) it is when the vehicle is parked.
Products abound to treat the mildewew smell, like airsept ( www.airsept.com ) but you don't NEED them if you follow the above guidelines.

Auto-recirculate and recirculate BOTH recirculate in the same way, but auto leaves recirculate OFF most of the time...
'Recirculate' is recirculate full-time, or until you stop the car and remove the key.
Auto recirculate means ONLY recirculate when the hydrocarbon sensor detects fumes being drawn in from outside (EG waiting in line behind a nasty, smelly Diesel schoolbus...)
Good times to use the recirculate button are AFTER the car interior has cooled down a bit, since at first the air in the car is HOTTER than air outside (the 'greenhouse' effect). Recirculating THAT air will make the car much slower to cool, and INCREASE the vent temperatures.
BAD times to use the recirculate button are when there's a lot of humidity in the car, such as having just climbed into the car wearing wet clothes after a summer rain shower... The cars windows fog up MUCH more readily when you use the recirculate.
Keep the fan speed low, and the vents get nice and chill. -If you like, I have a vent temperature probe, and I can easily SHOW how the air warms up significantly when you speed up the fan.

OI !!! I DIDNT ask the question !!!!! Dec did!!! See Thread #33!!!!!!
I know what all the buttons are!!!!!!
lol, its all cool! Oi ! Beanoir! we're good goofs though haa haa
