Haldex gen 5 pinout (Golf mk7, A3 8V)

Hi,
I am looking for a pinout for Haldex controller for my Audi A3 8VA 2013 year 2.0tdi quattro. I have no communication with haldex controller, so there are DTCs in most systems + esp light and parking sensors not working (no Awd also).
There are 2 connectors, 1 for pump, the other one is for controller. 1 positive wire, 1 earth, 2x can, ans one more that I don’t know what it is for.
Anyone knows or has a pinout?
I would like to work on it on the bench..
Best regards,
Matic

I think you will find the information you seek by buying access to the erwin.VW website and downloading the wiring diagrams needed.

The web site links are found in the Ross-Tech Wiki: Official Factory Repair Information

You need to check a diagram, but the other wire is probably a brake signal - a backup for the haldex, if it doesn't receive the brake signal over CAN.

If you have no comms, you could have a power or wiring issue... but the module may be dead too - sometimes they get water in them.
