Default Re: DIY: HVAC flap motor potentiometer cleaning

Here's another tip for running the flap calibration routine. If you press the ECON or A/C button at the same time as the button which directs the air straight at you, this will initiate a calibration of the FLAPS. The digital temperature display will show all segments, and the computer will do a 2 minute calibration (you'll here the flaps moving).
It worked for my EOS 2007.

I looked online, and it seems it's a custom part, so no one seems to sell it.... but, maybe some one could buy a minimum order and sell them to Audi / VW folk like us on EBAY?

Just a thought
