Boost problem

[ericd]

Any idea of the solution lol

run the output test in vagcom under the Engine section, see if you can hear the carbon canister activate and more importantly the n75 should make an audible click when you're testing it. post up what you find

Got a problem with the car, i think it's a boost problem but not too sure as i've not got a gauge fitted yet. The car seams to pull fine on 1/4 - 1/2 throttle but after that it really holds back and just splutters but not violently if you know what i mean?
Thought the problem was a boost leak so fitted a set of roose hoses but absolutely no difference. Swapped the bov for a new one i had from my old 3b, still no difference. Also fitted a new n75 again no difference

The vagcom is throwing up the following faults:-


Address 01: Engine
Control Module Part Number: 895 907 551 A
Component and/or Version: 2.2l R5 MOTR.RHV HS D02
Software Coding: PMC 1
Work Shop Code:
3 Faults Found:

01257 - Idling Speed Stabilization Valve (N71)
31-00 - Open or Short to Ground
01247 - Activated Charcoal Filter (EVAP) System Solenoid Valve 1 (N80)
31-00 - Open or Short to Ground
01262 - Solenoid Valve for Boost Pressure Control (N75)
31-00 - Open or Short to Ground

Don't think the first 2 faults would cause the problem?
The 3rd i expected to get as there is a bodge (not done by me) to the wiring to the n75.
Not too sure if that is the problem?
Any help would be great
