Might be a sticking waste gate

Anyway I can test this other than taking it to the garage??

Over boost is going to be..

Stuck actuator
Stuck waste gate
Leak in n75 to actuator pipe
Leak in charge pipe to n75 pipe
Faulty n75.

Any of these will cause boost to rise.

It goes like sh!t off a stick till it sounds like its about to explode,  I've only had the car a few weeks and after looking further into it the lad had unplugged the maf so it was running fine had it checked on vag.com and changed the maf yet it went haywire with maf plugged in, tighten all hoses etc and it calmed down, I did change to a yellow spring forge as the one on sounded like ur was holding open aswell as dumping the air but forge sounds the same. Getting frustrated now tho as I don't know what to do and can't afford to keep throwing money at it without solving the problem directly.

I would put money its the pipe from N75 to actuator split, i had the same..

Look at littco's list, its spot on.

It's a new pipe that was fitted a couple of weeks ago that came with the forge one. Been removed and checked but might renew anyway any ideas what size pipe it is? And is it the same size as the other 2 going into the N75 as I will replace those while I'm on
