Hi, I have a problem with my opel zafira diesel 2 dti 2003. There is no power in the engine as if the turbo is not working and there is no light in the dashboard indicating any problem can please someone guide me what to do?

Air Mass Flow sensor is the "normal" culprit for this issue (going by your description).

Also the EGR valve along with the swirl flaps in the inlet manifold can be all coked up.

You could try a bottle of Cataclean (Halfords sell it now) as that's fantastic for cleaning up the internals of the engine.

Did you get this sorted in the end and where are you in the UK ?

check intercooler/inlet hoses for splits,remove turbo inlet and feel for play in the impeller
