Hi all!

I have just finished this retrofit. If somebody needs more info, I can write down the whole process (not too hard, 3-6 hours), the needed parts, and make some photos about it.

The parts needed:

4e0 861 325 - Sun blind with motor
4e0 861 411 - Rear shelf
4e1 927 137 - Switch module in dash panel
4e0 947 111 G - Roof electronic (rear) with roller button
Some wires

The process (attached pdf file - pages are numbered as the steps needed, and the last page is wiring diagram):

- Remove back seat
- Remove trims
- Remove seat belts
- Remove rear shelf
- Add two wires from the sun blind motor (v91) to convenience system control unit (J393 - above the battery in luggage compartment) "A" connector (1 on picture) pin10 (-) and pin13 (+)
- Remove trim panel with switch module in dash panel
- Remove climatronic
- Replace the switch module
- Add a wire from the switch module (E461) connector pin13 to the climatronic control module (J255) "C" connector pin24
- Change the roof electronic module
- Now simply "rebuild" the car :)

The coding needed with vag-com:

08 - climatronic control module: add 64 to existing
38 - roof electronic: add 16 to existing
46 - convenience system: add 512 to existing

If somebody needs the parts, I can send all of them (used parts with new connectors, cables)

Hi Gerappa,
nice Work, do you have some real pictures of it?
If you need an instruction to calibrate the ACC let me know.

Of course. I can make photos about the connectors and the wires. Just need some time, because my phone isn't able to make good photos. :cry:

The acc calibration procedure would be wery helpful, thanks! :D
I have already made this retrofit, together with coding, but the only part is the gateway what I'm waiting for. When I plug it and remove cp, the whole system will be working.


Do you speak german, cause the instruction is in german.
If not I have to translate it
Sorry, but only english/hungarian. :-(
