I have a 2001 Audi A6 2.7T with 130,000 km. A couple of years ago, I started experiencing an intermittent problem of the A/C blowing cold, way cold. On "auto"set for 21 degrees C, the cabin temp would be 15 degrees, even if it was 21C degrees outside. Dealer said everything tested fine. Problem continued. Finally they agreed that something was wrong. Replaced sunroof dial. Problem continued. Replaced instrument cluster. Problem continued. Regassed A/C. Now, I have the opposite problem (not cold enough) if it's 30 degrees outside, and temperature is set to "Auto" and 21C degrees, the air conditioner seems to operate fine, but cabin temperature may only be 28 degrees (very little drop in temperature). Dealer says everything fine. Service Mgr. Says if I want 21C degrees in the cabin I have to set the temp. To "Lo" or maybe 18C degrees. I've tried 18C and end up with about 22C on a 30C degree day. I've always assumed that the ability to select the temperature implied that the car could achieve it. I'm told by service Mgr. That I have to adjust the temperature to suit my preference. Not cold enough? Ignore the temperature display and turn it down. Seems stupid to me. Why not just have high, medium and low settings? Is it true that the temperature setting effectively has no function on these cars as far as "controlling/maintaining" a pre-set temperature? The owner's manual says this: "Auto Setting- The air temperature, air flow and air distribution are regulated automatically to achieve and maintain the desired passenger compartment temperature as quickly as possible. The system compensates for changes in outside temperature and for the intensity of the sunlight entering the vehicle automatically". This is just what I would think. Interestingly, I checked my 2001 TT coupe, and it also only shaves off a couple of degrees- but I've never noticed because I usually drive it with the top down. I'd appreciate comments or suggestions.
have the same problem?
