suspected boost leak??
« on: 06 July 2009, 11:41 »
Feels like I've got a boost leak   :undecided: I'm getting some surging at mid revs when WOT.

Are there any common weakspots / pipes to check?

BTW, I've has my bypass valve checked recently, so this should rule this out?

Running Bluefin stg2 & upgraded forge hoses.

Ta in advance.

You need access to VAG COM to do some logging. Do you have it or know anyone near who does?

Yup, I've got access to vag-com, but that won't tell me which pipes are prone to splitting etc.., just confirm that I've got a leak (my butt dyno has been finely tuned over the years on turbo cars LOL!)

The usual suspects are the IC hoses!

Also as you have the forge hoses, did you transfer the O rings on the oem couplers on to the Forge couplers?

Additionally don't exclude the DV because you've recently had it checked.

maybe the DV ( divertor valve ) had it go on mine.

I thought the DV was different on the ed 30's?

What were your symptoms??

Different physical position to the standard GTi but unless you somehow have the latest version DV, it's still prone to tear...
