check all the vacuum pipes to egr valve,throttle housing,swirl flaps and turbo waste gate,make sure they are all secure and they are not damaged or worn through,also check the inlet and egr are not carboned up

Hi,
I have the same problem with my Zafira dti and have changed the glow plugs (another thread suggested it) and tried additives in the fuel to clean the engine.
Can anyone with a similar problem tell me if Simons solution worked and if so how easy is it to check and clean these things - how do I identify them for a start...
I am wary of going to a garage for a "no fault code" problem as it will cost a bomb and simply be a series of changing bits until eventually a solution is found.
Cheers
