I'd check the vakuum lines for the turbo electrovalve, and if they're fine i would change the electrovalve. It is a common fault on these.

Can’t really see much of that line, but if anyone can tell me the part number I’ll order a new one to be on the safe side .

Do you have enough vacuum at the turbo actuator ?

This had a new turbo right ? Was the fault present before or is it "new"

The original fault on the old turbo was OVER boost, on the new one it’s UNDER boost. Had vacuum checked by mechanic and he said it’s good. One thing I have noticed over the last couple of days is that the large air intake pipe to the turbo keeps blowing off (the one with the orange rubber seal). According to google this is caused by crankcase pressure, not sure if related but it wasn’t blowing off before I changed the standard radiator type clip for a jubilee clip.
