This is how I tidied mine up with 3m of vac hose from Forge.
I put my 1 way valve out of sight next to rocker cover between front and back of it, it now sits under the charge pipe and N75 piping. The vac hosing from it to front Y connection runs under the breather pipe coming from front side of rocker cover.
Hope it helps.

Use a small tipped screwdriver, push into bit that is raised (in pics looks like bit I mean has green paint blob on it) and prise open to release tension, then flick it off the peg it hooks on, if you get me.

Just be careful where it clamps onto the valves etc as not to break them.

Also when the clips are off the piping may still be tight, just use above mentioned screwdriver to break seal round end of pipe and then twist and pull pipe.

oh and ignore the state of my engine :whistle:

Am pretty impressed to be honest... Am no longer getting silly surges in boost and all feels a lot smoother..

Now i only need to get my vibrating exhaust sorted and i might actually have a fully working car!!

yeah, get it off. the only thing is the 2 bolts that hold on the nast lump of plastic are also holding in your coilpacks and are a bit long after removing it.

i dealt with this via a hacksaw and a thread file, but you could just get two shorter bolts.

i done the bypass today, car has been a bit dodgy when on boost in the last 3 days amd by removing the valve it's sorted the problem! the dump valve sounds bits more whooshy now aswell. well worth thinking about :>

I also did this on Sels (newly bought) std MK3 Cupra, with a Baileys DV and an open cone she gets a dump, the power also feels very smooth!

This is well worth doing once you have replaced that plastic recirc valve! lol
