Hi guys, I've got bit of a problem here. A few weeks ago a few of my manifold bolts come loose and so did the turbo bolts on my 1.8t so I parked it up as I couldnt be bothered with it. I've now fitted new manifold bolts and turbo bolts, so it's all bolted p and piped p nicely, now the problem is when I put my foot down the car just feels flat as f*#k like there's no pull to it! I had it mapped by r-tech about 2 months ago and it pulled like a train! Now I took the pipe off from the n75 valve which goes to the actuator on the turbo and it seems to be no vaccum, and with the pipe connected the waste gate isn't even opening, I can hear the recirc valve ever so slightly but not as it should be normally. So my question is do you guys think my N75 valve is past it?
Cheers guys

Anyone? I don't fancy wasting money un necessarily...
-
had it plugged in for fault codes?
-
Yeah, no codes have come up :s
-
From reading other peoples threads it seems as if it's gone into limp mode? I could be wrong but how do you reset this?

dodgy n75 valve will cause limp mode maybe worth try another 1
-
Yeah I'm going to pick up a new one tomorrow from Tps. How do I get it out of limp mode?
-
engine code?
-
Engine code is a AGU, I've put a new n75 on it and there's no difference.
The car isn't limited in the revs and reaches higher speeds then 50/60. So it can't be in limp mode,
I can hear the recirc valve only slightly but there is no kick In it it will rev upto redline stationery and when driven but it's like you can't feel the turbo kick in and the wastegate is definitely not opening... Pipes could be on the wrong way round but I doubt they are :s
-
limp mode on the AGU is only usually hit when there is too much air coming through the MAF, it's not clever enough to do anything else :grin:
-
When I went for the map nick put on my advisorie sheet "wet pcv system under manifold ready to split" would that have anything to do with it?
-
more than likely one of your PCV hoses has split then mate
-
Even with the PVC leaking you will still get a little boost.
Have you checked for fault codes?
Did the battery go flat?

It feels like there is little boost there as I can hear the 007p slightly, yeah it was parked up for a few weeks and the battery did go flat :(
I'll also throw in there that the brakes have gone quite spongey since having it back on the road Its probably got nothing to do with it but I was thinking could be down the lines of a vacuum problem?
I don't know its really stressing me out lol :(

Clean throttle body and do an adaption with VCDS this might bring all your power back... :wink:

Im going to have to try find someone local with Vagcom then lol
-
check the pipe under the inlet mani as thats usually split or the one coming out of the side of the rocker on the right hand side as you look at it

Solveddd!!!! Actuator was seized!! Woopp happy!

That would have caught me out, Never known one to do that.
Happy Days!! :wink:

is it easy to get too. i seem to have residue under my inlet manifold and im still getting a slight issue with boost

It was the last thing I was expecting it to be aswell to be honest. purely because I remember bringing it to you guys when you was mapping it and we was all talking about the actuator being a good one lol
Time to look into
Saab red top injectors
LCD pump
Ko4 turbo, mani and lines
