Dispatch 2.0hdi

Having replaced turbo and intercooler my van on start up idles lovely apply revs and it omits dark clouds of smoke as if over fuelling. Garage at a loss as no warning lights also no faults in diagnostics. It's a business delivery vehicle and off the road for three weeks! Any help much appreciated

Disconnect the air intake hose from the manifold, if it stops doing it there is a restriction in the air intake system somewhere, if not it is overfueling but as that is controlled by the ECU it must be a sensor somewhere.

Hi All

I have disconnected both exhaust and air intake at manifold and the van is still omitting huge amounts of smoke /fuel any help would be greatly appreciated as this is a business vehicle desparately required

A very strange problem for an Hdi. What colour is the smoke, I don't think it can be excess fuel or the engine would run away, I think its more likely that its being injected at the wrong time. If its blue/white smoke its unburnt fuel which could be due to an injector problem. Has the cam belt been changed recently?
