Im not familiar with audiworlds methods, just the correct ways to fix a car.....

Have you scanned it with a VAG COM? If not, do so.
You have to check the system pressures, which you can't do either.

08.5 Temperature Regulator Flap, static block, *08.5 (see below) that would be why its hot probably. Service manual should tell u or google it maybe, i think its visible on the passenger side kick panel i think it has a red arm.

sorry double post... oh and it says when it gives that code it is trying to move the door back and forth to dislodge whatever is in its way but it is failing to do so. thats on audiworld.com resoruces
