Hey Jaco2k,
just wanted to report that it works only partially on my Octavia III 2015 without memory seats. You need to have passengers side selected on controller knob ("R" in my case). It dips the mirror just little bit on reverse gear, but you cant adjust the depth how far it turns and store it for future. If you touch it after it dips, it doesn't go back where it was before, but turns up for just a same little bit as when it dipped on reverse gear.
Hope that makes sense
Anyways if you reverse it dips (lil bit), and the when you go forward it moves back to original position. You can force the "go back to original position" by turning the controller knob to "0" .
Btw I tried to code it with VCDS as found in other thread but with same result.
