Hello,

Hope my message finds you well!
I own a 2015 VW Golf 7R with a DQ500 RS3 gearbox conversion.
Today I have installed the RS3 Haldex to match the DQ500 RS3 gearbox.

After the install, the car appears to drive OK at first review. Will check more details later.
But I noticed that I am currently encountering the following error codes on the AWD module, after installing it, and they won't go away.

As always, any advice is more than welcome and I thank each and everybody for your time and help!
They are really appreciated.

Before digging into ABS coding, have you tried other codings for AWD?
0601 or 0001 ?

No, I did not try any codings yet.
I just installed it on the car.

I looked at the coding previously on my car and it was 0001. With the old Golf Haldex.
Please see below:

No fault code found.

Do you think this could be the culprit?

Fast update. Tried to update the codings to either one of 0001, 0601 or 0701. All give the same three already indicated error messages. :)

Okay.
Honestly I have no clue....

No other people that did the same retrofit?

I do not know. I will look around more.
After last night checks I noticed that it works perfectly. But have these three error messages.

Looks to me like the firmware in the RS3 AWD module is expecting extra messages?

Exactly my thoughts. And I know that the Golf 7 Haldex works with 7V and 9A current. The RS3 with 9V and 11A current. I currently have recorded 7.2 V and 8.9 A. So it still treats it like a Golf Haldex. I have performed basic settings of the Haldex Pump. Will test again.
If it still works like this i believe i can safely ignore the errors or switch back to the old Golf Haldex controller on this RS3 Haldex. That should work also.
