Hi, hoping someone can help with this one. (2009 2.0 TFSI cabriolet)
I can't switch the auto climate off so unable to manually change fan speed or direction of airflow (windscreen, face or feet). I have the car booked in at my local Audi specialist on Monday to run a diagnostic - hopefully it just needs a reset or something.
However I have been reading the forums and it looks like it is a straight forward job to pull out the climate control unit and replace but I'm not sure if the replacement unit then needs to be calibrated to the car or something.
Can anyone help?
thanks

Unfortunately, the Climate Control Module (CCM) is not a simple plug-and-play repair. Like most of the variable-voltage electronic parts, it will require the use of an On Board Diagnostic (OBD) device to run the Adaptation in order for the vehicle to recognize the new CCM. Basically all variable-voltage electronic parts like the CCM knobs, HVAC vent servos, throttle body, gas pedal, etc., work the same way; think of a dimmer switch in your house. At "0" the light is off and as you continue rotating the knob, it gets brighter until you reach "100" which is it's brightest setting. When the CCM is replaced, the vehicle needs to "learn" where 0 and 100 are by means of an OBD Adaptation.

You can read an older post on this topic here which includes a CCM Adaptation, VCDS 08-Auto HVAC Basic Setting and Output Test.

For more information on how to remove and install the CCM, you can refer to Workshop Manual HVAC, Heating Ventilation & Air Conditioning - RG 80 87 - D3E80068107 which you can find here. For more information on Adaptations, you can find a post in the forum Knowledge Base (KB) here. If you're interested in buying your own OBDII device so you can run your own fault scans and see what's going on, we have a review on the more popular ones here.

Fantastic info - thank very much
I'll see what the garage say on Monday after they run the diagnostic but if the unit is the issue i'll have a go at replacing it myself and then take back to the garage for the adaption - thanks

When you take it in, ask them to give you a print out of the fault codes. That way you know what they know. You can look them up easily enough. Just Google "Ross Tech XXXXX" where XXXXX is the fault code.
