Hot air from site air vents
 

I went through many forums and I can't find answer why my site air vents blowing warm air for the first 5 minutes. Centre once blowing colder (as set in MMI and setting is on middle). Even if outside is 27 degree C and inside the car 35 it sill blowing warm despite that I set for let say 20 degree. From where this warm air coming ? Obviously supplementary heating is off. Audi didn't find nothing in error log. many people got the same symptoms but no knows why. it isn't normal I think and it is annoying especially know when summer is full ON and I'm getting into the car where is hot as hell and for 5 minutes i got very warm air coming from passenger and driver site air vents. Any one got idea why is like that ??
Thanks in advance for any suggestion.
P.S. My car is Audi 2.0 TDI A6 [C6]

It is a known problem in the US. Send me a PM, with your e-mail address and referencing the differing temperatures between the inner and outer vents, and I will send you the TSB issued by AOA.

Hi, thanks for that
Temperature difference right air vent 25 degrees, middle 19 degree and left 26 degrees.

Thanks

What is TSB and AOA ??
Thanks

TSB is a Technical Service Bulletin, think of it as a suggested procedure to repair a known problem. In the United States TSBs are issued by AOA, which is Audi of America. I sent you the TSB on the AC problem.
