Hello Everyone

Hoping you can assist me with my troubles with the HVAC system on my Audi A4 SE 2.0 B8. I have hot air blowing out of the passenger side vents all the time, regardless of what temperature is selected on the heater display. Driver/Centre driver vents all ok. Actions taken so far are as follows :

* VCDS run and retrieved the below fault codes (V108 looks to be a failed unit so i can replace this, have one ready to go in).

* Basic Settings accessed and attempted to run calibration on channels 001,002. All retrieved ERROR.
