yep, it's high when the engine is warm. but before the car is warm, it reads closely to the correct temp. i've seen the temp sensor. it is two inches from the radiator. that's where the engine heat is exchanged! i'd rather it read low at first...

It is always off by 7-9 degrees F. And always on the high side.

I haven't a problem like this with my car.

Usually the temp directly after the engine start is mostly wrong, especially if the engine is warm. It needs some kilometers to bring it in its normal way.

When do you have those differences? Always or just after the start of the engine?

Mine reads 5-6 degrees F warmer than it should. I vote bad engineering also. The thermometer in the Ford truck I got rid of to buy this car was always right on the money. I'm not sure but I think I actually saw in the owner manual that it was normal for it to be off a little. I could live with 1 or 2 degrees, but 5-6 or 10-12 is too much. They should have calibrated it to read closer or moved the sensor.

Do any of you have a VAG-COM? I wonder if any errors are reported.

Also, there is a long list of diagnostic "tricks" that can be done with the Climatronic - I wonder if any could be related to calibration of the outside temperature sensor?

Actually, mine has kind of the same problem ... but not 10-12 degrees ... Celcius, anyway.

Don't know how much it is off in Fahrenheit, but it's typically 2-3 degrees higher in celcius than other outdoor thermometers. Always thought it was engine heat tricking it into believing it's hotter than it actually is.

And always thought that it had to take a lousy couple of engineers to place the sensor where it would be affected by the cars temperature...

yes, and that's the main reason why i'm annoyed with it. it is difficult to keep the car comfortable inside when the computer thinks it is much warmer outside than it really is

Does your Climatronic display the same temp as the FIS (center cluster)?
