0 bar boost! URGENT HELP PLEASE!

I would appreciate any help you all have to offer...:(

 

Picked up the car today from dudersvr - superb job and I would recommend on, just superb!:D

 

M23 and a needy kick down to strike a 2.7T Audi off the list and nothing! Just zip.

 

Issue is:-

 

Running smooth. Turbo's sound like they are spinning (pleasant whistle), gauge reads up to 0 bar during acceleration and then flickers and will not go higher, car struggles and is totally flat. No dash lights all are normal - car is normal up to 0 bar! HKS Super dump gives off nothing really when accelerated or at a stop and revved. When I first noticed I thought the auto gear box wasn't kicking down..

 

Green Flag idiot - had a look for loose or off'ed hose - nope... but not a clue me feels...

 

New FCD fitted today, thanks Pete arrived - nice;)

 

Could the FCD hold the car back like this with out causing the standard cut affect and dash light display?

 

Please help - desperate now the kit is on to play!

 

I do not have the tools or knowledge to play myself under the bonnet but have eyes to look and hands to feel!?

 

What hose if any could disrupt both turbos like this?

 

I REALLY THANK ANYONE WITH A THOUGHT

Read this... and >

 

I have now had 3 cases where the butterfly valve that diverts gasses between turbos has failed mechanically. Probably not a job you'd want to attack yourself, some tricky dismantling and perfectly accurate and heat shielded TIG welding required. Look down at where the turbo elbow meets the downpipe, there's a metal canister there with a small vac hose to it. It operates the valve in the elbow section via a quadrant, see if the quadrant has become detached from the rod it turns. There are ceramic parts within, and the assembly if bought new is VERY expensive

 

> at one of the arm - the 'joint that allows movement' there's a protruding bit which perhaps should have pipe on it? oh help ... I can't even explain - look > there's no pipe!

I was just trying to discount the FCD as that would be the logical choice but it had driven 30-40 miles with no problem , cant see the FCD having anything to do with it as the ECU doesnt control boost does it , seems like a hose type prblem to me , this car had another hose problem that was sorted a while ago so thats the logical place to look .

To the right of that circle is the canister on the FRONT of it should be a hose , if thats there follow it towards the front of the car and check all the hoses to and from the solenoid where that canister hose goes .

I was considering that the FCD could be attached to an incorrect wire(s)

Foot down - sudden loss of boost - car going along poorly - nothing above 0 boost

 

This is DEF the same symptoms of the intercooler pipe coming lose - check down under the battery tray

 

With an increase in your boost the extra pressure on the big hose causes the second large clip to come off

 

It's very difficult to see as down in the dark

 

I'll bet 50p on it m8

 

Cheers

Just checked that arm - to the right a pipe off to the front of the car all neat and tiy as are all the hoses I've individualyy seen this evening.

 

To the left of the arm, a joint allowing the natural movement - a nozel on the end of that which may or may not have a pipe attached - not there now. Is the arm itself propelled by a vacume pipe from the left.

I'm not sure if the kids are crowding around the car on this suburban and civilised country road street because of the kit or because a 33 year old man with a touch not knowing what he's up to is fumbling in the dark - and now Paul/John the cooler - great Barbie touch - thanks daughter..

 

always prepared.

The joint where I think maybe a pipe should be affixed to the arm to the cannister.... is found in 1. Looked else where and all seems ok... any under the heat sheild I need to look for or is this the FCD?

 

In your picture the canister just to the right of your circle has a rod coming out of it going to the left, at the end of that rod is this...

There isn't any pipe thats affixed at that side but there is at the other side of the canister (right hand side of your photo).
