could be an injector sticking.if you rev it hard does the noise go out of it.what colour of smoke is it blowing?are you sure its a diesel knock?has any work been done on the engine recently(eg.timing belt replaced?).is your oil pressure good?is the noise in it all the time or does it come and go?

Brian, as far as I know there is no manual adjustment on the EFI models, it's all done with sensors and the ecu. Have you tried any Redex in it?

black smoke is too much fuel but doesnt usually cause a diesel knock.its usually dirt stuck in an injector.get your mechanic to run the engine and open each injector pipe in turn,this should tell you which injector is making the noise.could some1 have put petrol in the tank by mistake?

could it be a big end noise?(hope not but can give similer sound if its gone badly because the piston hits the head.)
