Right guys what can it be ?...........

First of all it was all over the place one minute i had 3 psi then next i had 10 then i had 5 then full boost, then i had none then i had some etc Now its settled down! But its not running the boost it should be its only running constant 10psi and will not go over this..........Any ideas what it could be ?

Cheers

its your rocker cover

maybe a loose boost hose/dodgy actuator?

Sexy-RS

Rocker cover Dam is that what it is lol

Deffo not hoses as they are all ok

mine done something similar ages ago...turned out the bolts holding the actuator were loose as well as the bolts holding the exhaust housing to the turbo...or was it the inlet side lol...were loose...check all the bolts around the turbo an see if that helps

I had a split hose hat was fine on tick over and with leak detection spray but when the pipes were underload the split increased and opened it was only when it split all the way it was found

Really Great i hope its not that then

Bassboy i had that problem on it when i first got it I had it drilled out to take 10mm studs all good and tight as a whistle now

If the actutator was nackered would it do something like this ? its strange how it was all over the place at first now its constant 10 and will not go above What about the amal valve ?

I want my boost back

hmmm

check the bonnet raisers.. could be the car saying how much it hates them

joking, before you go off on one

Unfortunately Im not very technical.. so have no idea, but Jasesapphy's idea seems good

best of luck Faye

Yes but a tiny split wouldn't make the boost here there and every where would it surley?

bud-weis

possibly dodgy wiring on the amal valve ?

Robin

mine has started doing this, i know my acuator is softer than butter and it was wound out quite a bit but neaver held the boost so wasn't fussed, but took it for a drive lastnight, 1 min was boosting all the way up to 10psi then the next min was only boosting to 3 or 4. bit worried as the car is standord. amg oing to cheak hooses tommorrow and wound the actuator right down and see what happens

When my actuator went it decided to run at 22psi...... so at a guess if it was the actuator it run little or lots of boost Check yer amel valve as well as all pipes if all fails take it to a tuner or just blame alex

fay hope u get it sorted does sound like it could be a split pipe or weak actuator

Faye, my first suggestion would of been amal valve. My Esc Cos was boosting 12psi odd and then @ 4000rpm boosting up to 30 and back down, so SCC put a bleed valve on for the time being and set it to 30psi. Got a new amal valve, just waiting to test it lol

If you need any testing, etc speak to JB and Im sure he can help!

Sexy-RS

We have got a 2 spare amal valves i could try ...... But i didn't think i could just stick another on as Alex said mines been rejetted or something lol

Sexy-RS

Steve thats what mine was doing at first to i had like 5 psi then it would shoot up then back down lol But now its just constant 10
