Body control changes for sunroof retrofit

[Bainsey1695]

Great news.
@Robert @Pauly @mmi do you know where b464 is located for splicing into the speed signal wire? Or another convenient location?

Morning guys , can anyone point me in the right direction , looking at just behind the clocks at the minute but not ideal ? Cheers for your help

Could any of you guys help me with the location of the B464 that contains the speed sensor wire , need to splice into it , many thanks Steve

-It depends a bit what kind of van you have - assuming T6.

- A yellow 10pin-connector under left seat - pin 2 (white/purple wire).

- Also control unit in dash panel insert has it.
- Brown 10-pin connector in E-box

E-box is under the battery. Probably best splicing in where you found it at the instrument cluster.

Hi Rob , so I have retro fitted a oem sunroof to my T6 , wired it as helped out by Paddy on here and then went today to get it turned on with vag com , but even though it all says active , nothing is working on the sunroof switch

 

[Robert]

Sunroof controller is not accessible with VCDS as it is not connected to CAN or LIN bus.
It is sort of stand alone controller and, as mentioned already by @Pauly, only comfort function commands are send from BCM via dedicated 2 wires.

Right ok , so any ideas why it’s not working ? Is there any thing I could try ?

 

[Robert]

I presume it is a second hand setup.
Was it working before you took it out of the donor?

So is it just the switch and the controller that could be faulty. Are they just old school and need to start checking power supplies ??

Yes it was , and no did not see them working , I do have another complete set up , should I try them ?

 

[Robert]

Yes by all means if you have spare components try them. Maybe try different controller first.

So we have tried a different switch and motor but still no joy , think I’d be unlucky if all were no good ? Any ideas guys

At the sunroof control module check you have 12v at pin 4 and earth at pin 1.

Hi Paddy , yep 12 v at pin 4 and earth pin 1

Hi Paddy , yep 12 v at pin 4 and earth pin 1

Should this be a permanent live or switchable to come on with the ignition?
