Did the car run OK when you changed the SVC?

The car runs fine infact it runs brillant and very quiet, no they never checked the fuel pressure, could it be the fuel pressure valve sensor ?

I dont know how it ran until the SCV was done and and the pump reset there is a fuel rail high pressure sensor on the top left of the engine, if its faulty could this be the problem ????

If you had an issue with the pressure valve you would get either p0192 or p0193 errors codes, low, high pressure respectively.

you should clean the egr hole with carburetor cleaner. There is a spring loaded valve in there. It should move freely. If it's not clean the valve doesn't close fully, which will cause loss of power. I use to spray carb.cleaner in there while moving the valve by hand until I feel it operates smoothly.
And you should drive with the egr cable disconnected while debugging this. The 1.9 dci does not go into limp mode when egr cable is disconnected. I assume that also goes for the 2.2. EGR valve sticking will cause slow/late turbo pressure build up. When nissan say they replaced the egr valve, I think they just replaced the solenoid, not the valve itself. Your problem could be caused by boost sensor or maf read wrong values, which will cause the ecu to adjust fuel injection too rich (black smoke) or too lean (no smoke). Get a ECU readout of intake pressure and boost pressure while driving. That could give you a clue. |
