Hi, I removed my EGR valve from my Passat 1.9 tdi the other day to give it a clean. Managed to take off, clean & reassemble no bother.

When I removed the valve from the engine it had no gasket, it did have an o-ring on it. I then removed the pipe that connects the egr valve to the manifold and this did have a gasket.

Just wanted to check if there should be a gasket where the erg valve bolts on to the engine?

Thanks
