CRD Slow starting then black smoke when power on

OK replaced fuel filter with no joy, checked fuel pressure with OBD2 app and looks OK. Disconnected the harness from EGR with no change. Just to set my mind at ease I have done a cylinder cut out test with no change. (For those that want to know how just disconnect the harness from the injector on the cylinder you wish to cut out). The thing I don't like is when I am mucking around with these plugs the ECM should throw a fault but it hasn't been, I have heard that there is a relay that controls this but without a Nissan workshop manual its slow growing.

OK checked oil level and found it was a bit low so pulled out the intake hoses off the turbo, heaps of oil on the pressure side. So looks like I am up for a new turbo.

Bloody hell! How many k's it done

hey joelshero, ive got the same drama with mine. already blocked egr off as thats what i thought it was. replaced turbo also. now my next step is to do injectors, pump and may even need to do fuel manifold??? still not sure what it is though. any updates would be good. ill also update you if i find anything.

Shite and I thought the Di were a worry, seems the Cr have there own set of problems.
What with Geeyoutoo's oil pump coming loose, will follow this with interest now.
seems catch cans are a must as is the EGR block, who knows eh
Hope you're not off the road for very long anyhow
From memory you can swap the ECU relays with the air con one just to test it
I think it was under passenger dash, not 100% though

I hope you both manage to sort it out and post what the end result is.
I'm concerned after reading about the woes.

funny you say that three dogs. my ac fan stopped working about the same time...under passenger dash as in behind glove box or near foot well area???

Yeah but not 100% lh kick panel

have some more info...
OK i just disconnected my injectors one by one. you can here a significant engine idle/noise change when doing this. but for # 2,3 and 4 injectors, when i revved the engine there was no change in smoke. but, when i disconnected #1 injector the smoke was minimal. does this mean i have a faulty/leaking injector. this would explain the hard starting.

Hey guys not good to hear that there is others with the same drama. Been moving house so haven't had a chance to have more of a look and haven't tried anything yet. When I was moving the car to the new house I noticed my A/C not working, still got the fan though. I am back to thinking that this is an electrical fault. Can someone that has a good car pull the harness from any of the sensors and tell me if it throws a fault. I am busy unpacking for the next few days so won't be much help. But for those with this issue my advice is not to change expensive fuel system components.
