Just use a multimeter. Black to GND (i.e. 12v/cigarette sockrt) and red to LIN wire (i.e. in the door coupling point or door motor). Use the wiring scheme to identify the correct colour of wire.
I was tracing all the modules on lin bus 1 & 2 and was wondering if this could be it? I saw only 3 things on bus 2 the rest on 1. Just making sure im reading the diagram correctly.
j527 steering column electronics module
j386 driver door control module
j245 sunroof control module (bus 2)
g397 rain light sensor (bus 2)
g273 Interior monitoring sensor (bus 2)
j387 Passenger door control module
v26 Left rear window regulator motor
v27 right rear “” “”
j533 Databus on board diagnostic interface
h12 alarm horn

Sounds about right to me. In my polo the H12 has its own LIN pin on the bcm
Would anyone know if the j245 is still used on a convertible? I see it on the diagram showing it connects to j519 but cant find it anywhere on the location map.

No it's not, it's for the panoramic sunroof.
Why would they show it on the wiring diagram, for some reason I thought when you go on erWin the diagram you see is specific to the car.
Took awhile but i found out that the rear window regulators were shorting out to ground. Everything repaired itself after I disconnected the connectors cleaned them out some then reconnected them back.
