I was just wondering if anyone could help me... I had my Audi TT 8N X Reg regassed and my Air-Con still doesn't go freezing, it's sometimes go cold, but not always and 9 times out of 10 will be warm. I reset it with Diagnostic and works a little for like the first attempt (not freezing, but cold than outside) but then goes warm again, I plugged diagnostic in and this fault appears 00604 - Potentiometer Positioning Motor for Air Flow Flap (G113) I've read brief understanding of it on Ross-Tech wiki, however I need to know where it is located in the Audi TT, or if anyone knows of any guides where some one has done this. Forgot to mention, everything seems to function i.e Air-Con Clutch all that because when I drove it from the place I had regassed it was cold, but obviously after turning off and back on again it stopping or was not as cold as it was when had it gassed. I've checked for leaks, but I'm positive there isn't as the guy put Dye in so you can see if there was any leakage. Hope you can help thank you for your time.
