So, I'm totally at a loss.
Stripped all of the panels from the tunnel to gain access to the flap servos and all appear to moving and directing air as they should. I just can't work out how the temperature is controlled though???
Also plugged in VCDS and looked at some of the measuring blocks. Found that the left vent temp sensor was reading silly temps of around 35 degrees whereas the driver side was the standard 12 degrees. Decided to switch the sensors over which made no difference, the passenger side was still reading very high. Not sure if this is anything to do with the symptoms of no temperature control (always warm air to the drivers footwell and cold air to the passengers).
Also just found that hot air will come through to the passenger side if I use the rest function????? So confused!
I really don't want to take it to a garage, I hate being beaten.
