Hi, I've gotten:

01336 Combination Comfort databus (static) - 08 Air Conditioning,
01336 Combination Comfort databus (static) - 09 Central Electronics
01336 Combination Comfort databus (static) - 46 Comfort Systems

00470 Combination comfort databus in single wire (static) - 17 Dashboard
00470 Combination comfort databus in single wire (static) - 25 Immobilizer


Apparently my Convenience CAN is operating in single-wire mode.
I've checked the cables in the doors but can't find any breaks.

Apparently these modules are present in the CAN (door control (J386/7/8/9), comfort system (J393), parking aid (J446), electrical (J519) & memory seat control (J136)), but I can't find any wiring (WD) showing how they connect - I found this site/picture (https://portal-diagnostov.com/en/202...ring-diagrams/), but for the CAN-wires it just says "Computer Data Lines System" - i would like a WD of this system..
-> Can anyone help me with that?

Thanks in advance!

Car is: A4 Avant B7 1.8T (BFB), MY2008, produced 2007. No electric windows in rear.
