One minute I can have **** loads of boost then no boost then boost again change the vacuum box for a brand new one and checked the turbo no play spins fine could it be map sensor wiring

VCDS needed

It only comes up with p0324

VCDS needed

I mean p0234

Sure that's what code mine brought up and that was a map sensor

Anything more specific?. VCDS will have a fault code going over 2 lines usually, with a full description.

What was your car doing mate keep losing boost and going in limp mode mate

OK - googled it and thats the overboost code, so basically you're probably looking at the sticky turbo vanes scenario - If you have the time/cash I would personally remove the turbo, inlet manifold and EGR, and strip both down cleaning out of gunk.

PS: Dodgy MAP sensor usually has a fault about not being able to read the signal, or an "open/short to +" which usually indicates a broken wire or faulty sensor.

I had the turbo of just a few days before ultimate dubs and cleaned it all out that's what baffled me

Then I am wondering if you put it all back together correctly? Did you put everything back as was - i.e same actuator setting / stopscrew?

Yeah mate just been thinking through it could be sticky vains because from cold it fine boost hard but soon as its warmed up it goes into like limp mode

Use VCDS to log group 11. It'll show you the actual vs requested boost.
