I forgot to mention the V70 is the one with black lever in the middle

I just checked mine today. It seems that the potentiometer has gone. The problem is that a second hand one will not last for too long. So best solution is a new one. Will have to visit the audi service parts. 

First option: use VCDs to diagnose module 08-HVAC, probably you will get same code as me- that shows a faulty or blocked positioning motor for central flap(V70). First i tried performing basic settings, and no joy . Jow the fault code is saying : potentiometer for this motor for central flap -adaptation limit surpassed. Basically you need to take of the glovebox and search for the servo motor with black lever, part code is : 8E2820511H. There is a video on youtube how to acces these climatronic motors:
