I have been wanting to get the proper reverse mirror dip working for a while. Not the dip a tiny amount and vaguely return to the original position version I had.When I fitted the folding mirrors, I did upgrade to the high line door controllers, but that wasn't enough. I needed the Memory Mirror Motor (part 3D0 959 578 C). I managed to get one from ebay, but it didn't come with any wires.
So following https://forums.vwvortex.com/showthread.php?6960609-Mirror-tilt-possible-without-memory-seats-Possible-DIY/page2 I cut down a larger connector to fit. Also note in the thread about the pin numbers. They aren't what you would expect.
Pin out
7 5 3 1
8 6 2
4 is the blank.
Now all i needed was the pins numbers for the door controller plug.
@SashaGrace pointed me to this thread which had the door controller pin numbers
I enabled the reverse mirror dip with VCDS and found that with the motor I had bought, horizontal and vertial were the wrong way round, so had to swap all the horizontal / vertical wires round. So I ended up with
Door Controller Memory Motor
4 5
5 6
7 2
8 8
13 7
14 1
16 3
And after all that, my vertical is the wrong way round, just like for @Trust2k. So my pin numbers may be specific to the variant of the motor I have and for someone else might be slightly different. But wanted to have a post with all this in one place, rather than dotted around.
All in all rather have the working reverse mirror dip. It really does work properly. Just really, really wish VW, Skoda, Seat etc were consistent with their parts, as even when a part has the right part number it might still be wrong because it came from the wrong make.
Moral of the story, I suspect, is buy the unit from aliexpress that is marked for skoda. A lot less hassle I suspect.
I will update this if I ever get my up and down to be the right way round.
