I just get the code this morning from dealer. He found ECM 6805. He (the dealer) told me to come back and leave the car for a thorough troubleshooting, but it's a 2-3 hours job and would cost between £125-£225 just for the diag ! As mentionned by outnumbered (Mike) I'll have an injector leak off test done by a bosch station.
However any idea for 6805 ...

Hi there,
Well I'm still doing some test on my car and I found something weird. I went under the car to connect a vacuum gauge to compare the figures with the ones outnumbered gave us in the link above. Engine running, I have the same figures but the VNT rod is pulled to its maximum at 30 hg/cm and move downward 1cm then stops. What do you think about this short stroke ? And what do you think about the fact that it stops moving at 30hg, it means it reaches its max flow at 30hg, is it enought, too much ?
There is also some oil on the body, here's a picture, is it a sign of seal failure or normal ? Thanks for your help, advice...

hi
i could only move mine on a static test to 28 hg so if you are getting the same as mine i would have thought that was okay, so start on the others, as for the oil leak that is the oil retrun pipe for the turbo you can buy the two seals easy to do.

28 hg, same for me....
As read in your troubleshooting topic, I found the charge air hose soft, the engine is cold now and I can easily squeeze it, for the moment this will be the next part I'll buy.
I also spotted oil and the valve cover/air intake cover. It's greasy all around injectors 2,3 and 4 and there is oil in the injectors wells. I think the gasket may be torn apart, would it be enough to loose intake pressure and going into limp mode ?
Aside from all these questions, thanks Mike for giving me the figures you found on your car....

its not a gasket its sealing compound, you have to take all the pipes off and re seal, then you have to purchase all new pipes tad expensive as for the intake pipe if you find that its too soft then change it as that could be sucking in under load causing less boost .or you could try and strenghten it on the inside with a coat hanger so that it does not colapse but i would not do that just in case some foreign body got to the turbo.

sorry, if you take off the rocker cover to re seal you have to take all the injector pipes off, they are not re usable and the cost for all is expensive.

Too bad Mike, I can't reply your PM until I get 30 posts, so here's my answer !

Do you mind if I call you tomorrow, I have no time tonight. Just tell me what moment you would prefer. Tomorrow morning or afternoon would be easier for me... Keep in mind that it's easier for me to write english than talk by phone but that should be ok as far as you don't have a deep northern accent and local specific vocabulary! Lol !!
