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

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 :)

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

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.
