Atlas_RWG Thanks for the reply mate appreciate it. I just got back from the mechanic, they said they have checked all the solenoids and vacuum areas where it could be a leak and they said it looks all good.
Not the areas they looked.
The turbo to intercooler and from there to the inlet.
Unless you can see them fully all around there can be a split.
Is the maf sensor reading correctly when tested?
If they don't know these cars then that's no help.
You have already started spending money on them just throwing parts at it , they are useless. Go to a shop that can DIAGNOSE the issue not just spend money hoping it fixes it...
