AGR for 1.6 FSI engine

Hi.

An Audi A3 MJ06 likely has what's known as "rainers," meaning it's experiencing excessive wear on the camshaft lobes. This is indicated by a loud rattling noise coming from the EGR valve when the engine is started, and the engine is running poorly.

What types of connections does the AGR valve from the 1.6 FSI engine have?

I can understand the exhaust inlet/outlet and coolant functions.

What bothers me most is the flange on the head.

EDIT: Wow, I spent an entire night searching on Google and found NOTHING. Now I see that it's not even a flange, just a smooth surface for screwing things onto.

Okay, then I guess the only solution is to replace that part...

Greetings.
Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

No.

new finding:
It's a flange attached to the cylinder head.

What is it used for?
What is flowing through there?

The guys with the 1.6 FSI engines aren't taking pictures.

The AGR valve appears to be structurally the same for the 2.0 FSI engine.
There are pictures showing his tooth falling out.

If the central incisor is affected, try rotating it.

This afternoon I'll know more – I'm going to open it while it's installed.

EDIT: Tooth failure on the valve shaft, so it's not a simple fix .
