I decided to take full day out of my vacation and close some DTC's. I've fixed my license plate light as well as parking sensor problem that's been with me for a year or more.
I then started at my HVAC fault code:

Code:
Address 08: Auto HVAC        Labels: 8E0-820-043.lbl
   Part No: 8E0 820 043 BK
   Component:   A4 Klimaautomat   2833 
   Coding: 00000
   Shop #: WSC 00000 
   VCID: 6B83C7F20A965C43969-5118

1 Fault Found:
00716 - Air recirculation Flap Positioning Motor (V113)
            41-10 - Blocked or No Voltage - Intermittent


To do this I removed the glovebox and ran the 'Output tests' on HVAC while observing the flap motors and listening / feeling the HVAC functions.
Everything seemed okay (each test caused something to happen) except for the V113 test. The flap circled in the below image never opened and so I concluded that flap would be run by the V113 flap motor (also circled).

I then went on to order a 8E1820511L (L revision) flap motor costing me near 200$ shipped. Well turned out I paid for expressing a revision D which is the old version already on my car :banghead:
Don't know why I still bother with eBay but that's a different topic. Anyways, I installed this unit and still nothing happens on output tests. That flap isn't moving.

I then did the code reading from with the HVAC context menu and now I am getting additional codes:

Code:
7 Faults Found:

00710 - Defroster Flap Positioning Motor (V107)
            41-10 - Blocked or No Voltage - Intermittent
01272 - Positioning Motor for Central Flap (V70)
            41-10 - Blocked or No Voltage - Intermittent
01809 - Actuating Motor for Temperature Flap; Left (V158)
            41-10 - Blocked or No Voltage - Intermittent
01810 - Actuating Motor for Temperature Flap; Right (V159)
            41-10 - Blocked or No Voltage - Intermittent
01274 - Air Flow Flap Positioning Motor (V71)
            41-10 - Blocked or No Voltage - Intermittent
00716 - Air recirculation Flap Positioning Motor (V113)
            41-10 - Blocked or No Voltage - Intermittent
00735 - Potentiometer in Positioning Motor for Air recirculation Flap (G143)
            09-00 - Adaptation Limit Surpassed


I don't know if these codes are caused by the series of Output tests or by installing the new flap motor.
Running a full scan (below) after clearing DTC's they all come back.

Not sure what to do next. Are there adaptations or coding to be done (how?).

Many thanks in advance

Also, when running Basic Settings, everything goes to 0 except 8,9,10. AFAIK the test does finish (there's no user feedback):
