Warped Coolant flange (S3 AMK)

This is the mounting face to the side of the cylinder head. Looks warped/untrue to me and must be the cause of my water leak.

There's no part number on it so i'm guessing its aftermarket. HAs anyone replaced this with a gen audi one and has the part number please?

i am assuming the face should be flush! theres an o - ring to seal...

Not such an issue if not entirely flush due to the o-ring which seals it up. If you're concerned though they're pretty cheap and quick to swap over.

Etka.cc for a part number (looks like a 06A121132Q perhaps?), or just search for something like "1.8t coolant flange" on the online auction site of your choice.

Cleaned both surfaces and re installed. Leaks like a good'n. The unflat flange doesnt let the o-ring seal. New one ordered, fingers crossed!

when my one failed it was because I put the incorrect cap head on so there was no washer supporting the plastic in addition to the metal insert, and the plastic moved on the metal insert.
