Hello all and I hope you are well.

I have bought a repair kit for the PCV valve (AH) revision.

Does anyone know how to remove the round disc part so I can replace the gasket and spring inside please?

it has various grey clips underneath,thought I could spin it loose but no dice.

 

Thanks so much

 

Work your way around pushing retaining clips in whilst applying a little upwards force on the cap.

Great help thanks so much MicMac.

got it in the end with the help of a VAG sensor clip tool.

The diaphragm was fine/not torn after all but was peace of mind to check it.

There is an “Audi PCV diaphragm “ video on YouTube also to help anyone in future.
