[Subbiah06]

howsit gents,

i've been having an issue with my 2012 g6 gti dsg, i have been getting CEL on boost (000665 - Boost Pressure Regulation: Control Range Not Reached)

Things ive done:

* new turbo core (oem)
* new dv (vw fitted)
* new engine speed sensor
* new maf sensor



car is currently at the shop have the boost pipes and intercooler being checked out?


any advice as i am getting fed up?

Have you tried changing the N75 valve.? is it stock or is there is map loaded?.
What is the requested VS actual.
What does the N75 duty cycle do.
Have you pressure tested for boost leaks.

car is stock, dont have much feedback for you as i dont have the equipment for testing, but no the n75 valve has not been changed? anyway to confirm if this valve is damaged?

Just need a VAG COM cable bru. There must be someone close to you that can help. Visit any reputable tuner. Also, check the dipstick O-ring for tears. and whilst the car in running remove the dipstick to check if idle remains the same or it starts to choke a little - that will verify PCV is okay if it starts to choke a little .
