Small pipe from Airbox on TDi

[trebormint]

Want to fit an induction kit on 02 Toledo Tdi, but this will mean a loose pipe with nowhere to go!

I notice this pipe leads to alot of pipework and a couple of valves.

Is this a vacuum pipe or does it just pick up filtered air.

What's best to do with this pipe?

It is the atmospheric pressure feed to the solenoid-driven pneumatic valves that control things like turbo vane position, EGR opening and the like. These valves create a pressure between atmospheric and full vacuum by toggling between the two. The feed should be taken from behind the air filter, in the "clean" air feed.

Thanks for that.

I've plumbed the pipe in post air filter, pre MAP.
