i have had a problem with the aircon/heating for a while(2002 a2 1.4tdi with aircon) and recently had the opportunity to replace the servo which i thought was faulty.
the problem i have is when i turn the temp up the air coming out of the vents will alternate hot/cold and i can hear the servo moving (temp servo bottom one to the left of the radio din unit) i have changed this servo and the one above it, although it has now stopped moving of its own accord there is no change in what it was doing, i have also changed the temp sensor which is located behind the radio and i am still having the same problem of alternating cold/warm air when i turn the temp up, ps its fine when set on cold it only happens when i dial the temp up over 70 ish.
i have tried a vagcom reset , it lets me log in to auto/hvac 04 ans starts flap reset procedure the panel in the car goes into reset mode but after about 10 seconds in the flap boxes which are supposed to reset to 0 (in vagcom) it shows error somthing like 07? in brown writing across each of the flap boxes, i then have to turn off the ignition to reset the air con unit.
any ideas??
also does anyone know the correct positioning of the flaps on re install, is there notches for correct alignment of the flaps and servo's?? as the elsawin diagram does not seem correct for my model? (yes i have searched across elsawin for the a2 2002,3,4,5 and all diagrams are the same.)
