I have a 2001 galaxy 1.9 pdi ,was running fine till yesterday and now starts ok but wont rev up.

I have checked the vacuum pipe from the turbo,checked for any leaks also,but still it has no power and wont go over 30mph.

Any ides much appreciated.

It could be due to a lack of boost, possibly a blown turbo or the boost is not reaching the inlet manifold for some reason
