limp mode

[uzi_cupra]

ok guys, basically my car has been running in limp mode for the past few days a. the engine management light came on so i checked it and the fault was
charge pressure control negative deviation, intermittent
now all my hoses are fine, the car does not smole at all when in limp mode, i just get no boost at all. i stripped the car, took the intercooler off and checked all my pipework and it is fine. i then took apart the egr and took my inlewt manifold off which was full of GUNK! i cleared the fault and the car is still in limp mode, im getting no boost and it does'nt seem like there is anything not connected.
any help would be appretiated

You should really see a doctor for limp mode...







Sorry, can't help with the main question!

Have you had it mapped to suit ur hybrid turbo? That could be the one reason. I also assume that you have turboback which needs map tweaking also... so car being in limp mode doesnt surprise me at all..

Its not map related

Same code, same symptons, and the fixes:

A bad Turbo Actuator
A clogged intake and EGR/AntiShudderValve - Causing the Negative pressure code
and a plugged vacuum check valve. causing low boost
