brum guys help me!!!if u can
 

evening all

has any of the birmingham lads got a actuator that
i can borrow or even a cheap one to sell me so i can see if mine is faulty
ive got a TD05H on mine but im lead to believe that a TDO4 actuator is the same
dont want to spend mega bucks to find out its not the actuator


thx

steve

give us a shout if u need help
 

Sorry steve i aint but if u need a little loan short term come give us a shout ok no worries

m ward

ive got one here off a td04 you can try. never used it myself so not sure if its ok but it should be

thats great just got to get it of u now
where abouts are you??


steve

pm sent

thx for that
was gonna do it tonite but the footy is on soon

steve

Hope it sorts the problem out for you.

changed the actuator this evening and guess what happened

yep you guessed its still the same
only boosting to around 7-8psi

im off now to pull my hair out



steve

Thats a weird one.

A post on technical might be in order i think?

check solenoid, boost pipes for leaks etc.

solenoid was cleaned the weekend
all pipes were taken of and checked for any visible damage


steve

You could try removing the actuator pipe, and see if turbo boosts. Be careful when doing this, keep an eye on your boost gauge. Dont let it boost too much. Back off as soon as it hits 14psi for eg.

and this would prove what exactly??

problem most likely lies with piework or boost control.

so if i take the pipe of the actuator do i need to clamp closed or leave it open
and if i hit the target boost of 16.5 psi would this mean the boost solenoid is faulty ??

and what if it still wont boost past 7-8psi then what could it be???

steve

Just pull pipe off actuator nipple, no need to clamp or anything. What should happen is that actuator will stay shut, and allow turbo to spin out. Be careful when doing this, as you effectively have no boost control, and if turbo is working well it will continue to build boost very quickly.

Once you have determined that the turbo is willing to boost with no undue noises etc, then you know problem lies somewhere else. Like you say, it could be possible that the solenoid is faulty.

Another possibility is spark plugs or spark related. Have you noticed any misfire or hesitancy?

no misfire at all
car is running perfect
pulls well aswell thats what i cant understand
will try the pipe 2moro after work



steve

just another thought i had
when i cleaned the solenoid i sprayed brake cleaner in all the pipes
connected the diagnostic plugs and switched the ignition on
should it have sprayed out profusly or should it just dribble out??


steve

Thought it sprayed out with a little force rather than a dribble steve,not had to do it myself but thats what ive read on here im sure.....

martin

quick update

have just taken the pipe of the actuator
and fcuk me the turbo spins up no bother
first time ive seen 14psi for a while now

so im think the problem lies either with the boost solenoid or the pipes coming from it
in which pipe is the small restrictor
as i cant find it


steve

Its worth pulling each pipe off one at a time and check for blockages or oil contamination.

If your car has the 3 port solenoid, there will probably no restrictor.

yep its the 3 port solenoid that is fitted

me thinks now its the solenoid

any1 got 1 for sale ?????????
