Hello! I've read this forum quite a few times and find it very helpful!
I just tried using the VAG-COM from our workshop to adjust the AGR (Abgasrückführung) settings as described in the technical report.
So, I went into the engine electronics, but I made a small mistake!

I entered the value 3 during the coding process! Here's the translation:
"Now, under the data, it says:"
01 - Motor electronics.
038906019CK
1.9 R4 EDC 0000 SG 1243
Encoding 3 (This ad is meant to be displayed!!!!)
Company registration number 47791.
Unfortunately, I don't know what I did wrong now!!!???? Is this something serious, or can I continue driving normally?!?!?
I really don't know much about the VAG group at all!
If someone could help me, I would be very, very grateful!
PS: And I still haven't found the measurement block for the EGR!
Best regards,
Timo
