Auto HVAC security access / login code

My Octavia 2007 had faulty HVAC unit 1Z0907044J. So I bought newer unit 1Z0907044AC. After the swap I noticed 1 of 6 HVAC servomotors doesn't rotate. Then I found Skoda TPI 2020543 which states that models from 2008 onwards have only 5 servomotors instead of 6 and my new HVAC unit 044AC is intended for 5 servomotor setups. Luckily 044AC can be adaptated to make it work with 6 servos, instructions are in that TPI.

Skoda's official TPI instructions are for a VAS tester. I don't have a VAS, but I have (official/legal) latest VCDS. Unfortunately "Adaptation" menu is grayed out in 08-Auto HVAC.

Does anybody know HVAC security access code / login code for Mk2 Octavia? I'm hoping valid code gives access to the Adaptation-menu, but I'm not sure if it works that way...
