I have the dreaded heater problem whereby it will go from the extreme cold to extreme hot with nothing in between. I have changed the V68 temp flap motor but the same problem persists (ps you can change the motor WITHOUT taking the dash out, just remove the lower trim panel). I have run basic settings on VAGcom and interestingly the only value it ever shows is 255, i understand this should show 0 as standard. I think the AC switch and recirc buttons work, VAGcom shows the compressor comes on
