broken car

[Dan20vt]

Hi folks been having a lot of trouble with my car the last few days at first i replaced a coil then maf plus plugs and i still have no power the n75 is reading 100% and the maf about 100 i think just noticed the turbo actuator is not moving at all does this have anything to do with limp mode?
only fault showing on vag com now is Charge Pressure Control: Negative Deviation
Cheers Dan

Cheers mate im trying to get seat to pick it up today its giving me to much greif now lol if they dont i will take the pic...

Does anyone no if the actuator should actually move when you rev the car up in limp mode mine dosent feel seized but its not moving when the car is reved up..plus engine light is on and in limp mode
Cheers

your actuator will only move if your on boost, ie, moving, unless you ride on the clutch and rev.

Your on negative deviation mate, means your requesting too much and its not delivering, e.g. boost leak, take martyns advice

 

[Dan20vt]

Cheers for the advise, i just spent an hour at seat with a technician and its lookin like its goin to be one of them nightmair faults to find.
possible cat blocked anyway there will be further investigation done tomorrow now Cheers

if the n75 is pegged at 100% and ur seeing neg. dev. u have a v serious boost leak between the turbo and inlet mani , do you hear whoosy noises, have u traced all the pipes checking for splitsor open joints

 

[tackleberry]

i said boost leak. did you check any of the pipes after dan?

 

[Dan20vt]

I checked to see if i could hear any air comeing out the pipes when it was reved up and they all seamed to be in quite good condition, it is a possibility but it must be a tiny hole..

 

[tackleberry]

a car stationary does not come under boost weather revved or not mate the only way to find a boost leak under load is on a rolling road i.e jimmy did this on his at westec

 

[didgy2]

is the car still in ross? we could have an afternoon going over it

 

[Dan20vt]

The car is at hereford seat. is everyone saying this could be the only problem or is there a chance it could be the cat blocked still or something like that

 

[RS SHORTIE]

I had a boost leak yrs ago on an uno turbo and the rolling road guy sprayed wd40 around all my hoses to find where it was coming from.As soon as it got drawn in the revs went t*ts up.
Also another time i had to take the airfilter off and place somthing flat over the induction hose,if it keeps running you have a leak.

Im not sure these will work on your car but might be worth a shot if you have'nt done so already.And would rule out a boost leak atleast.
