Retrofiting power folding mirrors - C30

[AlphaScorpii]

Volvo C30 2012. without power folding mirrors:

I've changed the mirrors and driver's door module (DDM) with the ones that have the option of electronically folding.

Good news is that all the previous DDM functions work (windows going up and down, mirror moving..) but power fold when pressing L+R doesn't work nor does puddle lights when pressing light button on the key. I've taken picture of the wiring adapter in the doors and it has 12 pins although defult mirror had 8 pins (new one power folding has 10). I guess that means that wiring is the same for all the models. At least door wiring. Not sure could there be some other wiring that is different?

Not sure what is the next step.. should I go to the dealer and try "DDM upgrade" (30669922)? I don't want to waste money "gambling" on different software updates . I am not sure could the dealer see right away what do I need when they connect car to the computer.. I don't think anyone ever changed mirrors from nonfolding to folding in my city.

I guess doing it without a dealer is not possible?

Hey alpha, you ever figure out why the puddle lights weren't working?

I have a thread running on the P2 forum on retrofitting the folding mirrors to the P2 that was not fitted with them originally.

The main issue in that case is that Volvo had software to basically toggle the CEM as I understand it from not fitted to fitted. For me the problem there is the software is now listed as NLA.

However, another member added information on how to find the pin # for the CEM and then modify that to do the toggle. Currently I am trying to find suitable parts including the center dash column button for the folding mirrors.
