Hiya Marc, thanks for reply. Yes its the same as your C5 II only gold, not black.
Symptoms; starts fine, haven't noticed excessive smoke, all is fine until engine up to temp, then, almost no boost.
Feels like a pre-turbo diesel like an old ZX I used to have.
Still have no idea where to start looking, HEEEEELP !

Check the thermostat - is the car gauge showing heating up normally or too fast? If the engine ECU thinks the car is overheating it may stop the turbo boost - especially as you say this is happening when the car is up to temperature.

I'd check ALL your vacuum hoses for leaks and all your turbo hoses too - make sure they aren't kinked or sticking together when hot.
