VW Golf 4 1.8T: AGU/MSG ECU to Polo 6N WFS

hello,
First, I'd like to briefly introduce myself:
I'm Sven, I'm 35 years old, and I'm from Berlin.
I recently purchased a full version of VCdS and have already been able to do quite a bit with it, and I'm very satisfied!

Okay, I'm facing a problem: I want to connect a Golf 4 AGU engine control unit (ECU) to an existing and functional WFS system in a Polo 6N.
I've already tried those, and they work, but the new Golf AGU MSG is being blocked.
Error code: 17978.
How do I proceed, and what login codes do I need, specifically for the Polo or also for the Golf?
or is it possible without codes?
I would like to thank you in advance for your help and for a detailed explanation .

AGU Golf4 = WFS II

Your Polo might still have a WFS I system (a 6-pin box; the WFS II box has 8 connectors). You need at least the login code for the WFS box .


Do you have a 6-pin, forgotten

hello mulle,
Thank you for your quick reply .
I need to check if it's a 6-pin or 8-pin connector.
problem, I don't have any code .
Is it possible for me to obtain a WFS (window film system) from you, specifically the key, the WFS spool, and the code?
Is it possible to integrate it and configure it, since there's already a code available?

The other option is that I have the KI (key immobilizer) and the keys for the Golf AGU engine, but I don't have the login code. However, everything was working before...

I have an 8-pin box installed, which is likely an IMMO2 system.

Then, determine or retrieve the login information. Alternatively, check if it's attached to the keychain (scratch off) and then pair it.

ok, thank you. Can you please briefly tell me exactly how the process is to be done ?
Sure, here's the translation:

"Thank you in advance."

Which process?
