CRD Slow starting then black smoke when power on

[Joelshero]

G'day,
Been trying to nut out this drama. Got home from work the other day and the missus tells me the car is getting hard to start. Told her she needed to let the glow plugs do their thing and thought nothing of it until she rang me and said it was blowing black smoke. Its not long after a service but not discounting bad fuel yet (will change fuel filter tomorrow). But over the phone sounded like it had a hole in the intake after the turbo but on inspection nothing found. the vacuum actuator on the turbo seems to be working fine. Have heard of exhaust blockages causing similar probs in other makes so disconnected the exhaust from muffler at the flex joint at the front of the car with no joy. I haven't got any manuals and am desperately chasing info.
Any suggestions would be helpful. I am a qualified heavy vehicle mechanic and after reading some of the stories on these forums of people forking out thousands for no result or short term results I am reluctant to take it to someone else even if they are a so called specialist. By the way she is a stock standard 2011 3L and no fault codes recorded.

Just scanned a page from workshop manual on the black smoke....

Have you got the section on testing the EGR valve please. No wonder most blokes go strait to injectors and pump when they are the first things mentioned. They will be the last thing on my list.

[threedogs]

most here would have the EGR blocked off,
I'd be looking at dirty Injectors or MAF being Dirty

[rottodiver]

The chapter really doesn't say too much about how to test.... I would just try it with the plug on and then off( have heard of people disconnecting that vacuum hose and stopping the smoke. Here is the diagram of where to find it...

Maf is clean as is intake, injectors only 50k old, I am not paying $2000 for a set of injectors for the same guy to tell me the pump is stuffed and its gunna cost me another $4000. would like to test the cheap and simple stuff first. As I stated in my original post there are no error codes. The stuff that I normally work on will throw a code if there is an air flow sensor fault. If it was an injector fault it would be running rough at idle and there would be a loss of power, besides in my experience it is very rare for all injectors to fail in an engine at the same time.

Thanks rottodiver I will have a look at that and give it a try and let you know. I should be able to work out how to isolate it and see if the problem hangs around. Is that the picture for the common rail or the direct injection model as it looks like an injection pump in the bottom right hand corner of the picture.

[rottodiver]

The picture must be di but the egr on crd is the same side but further to the front of the motor...
