Its the one way valve for the diff lock etc, it stop boost pressure blowing it to bits.

Thank you.

If i seal the vacum hose to the manifold is the car safe to drive?

Yeah, but im not sure if the diff will stay unlocked??? I think you will be ok.

I broke the nipple off this one way(?) valve whilst trying to replace my vaccum hoses.

What is it and what should I ask for (part number?) when I call VAG parts in the morning?

Many thanks...Angus "Mr Heavy Handed"

Yep you can safely blank it off - only problem will be inability to operate difflock and the recirc valve for aircon (if fitted).
