HVAC:

Address 08: Auto HVAC (J255) Labels: None
Part No SW: 4G0 820 043 L HW: 4G0 820 043 L
Component: KLIMA 4 ZONEN H12 0062

0292 - Running-in regulation
B10C6 54 [009] - Missing Calibration / Basic Setting

Backstory is some work was performed on the HVAC, details unclear, but the system was pulled down to vacuum for +15 minutes then recharged as per factory specs. No AC operations now, has DTC B10C6. Code gets reflagged if cleared out.

With engine at idle perform the two Basic Settings:

Adapt flap end stops - Finished Correctly!
Compressor run-in and A/C power test - Finished Correctly!

Now able to clear DTC and AC is working to design.

I´ve seen simmillar strange thing in A3 2016 that came to me for refill after change of condensator and AFAIR(-emember) no DTC but the AC not running (checking all possible conditions to met) till I have performed (with engine running at idle and AC switched on) basic settings of AC compressor (was original but needs this to start working again...). Don´t get the purpose or what exactly this procedure do (when commonly the "run-out" of a new compressor is usually "just" max.cooling at idle for about ten minutes...) but takes just a moment and then it starts to work again ...
