John,
EGR Valve is opening and closing (tested using Techstream)
The fueling could of been the issue? I will top that up!
Well as far as I know it does, I don't have an DPF Error on the dash, however, it smokes constantly! I wanted to try a regeneration before purchasing a 5th injector and trying other routes.
Also - I have once tried and failed with replacing the DPF, the one I bought was the wrong one for the car and so the old one went back on! when i looked inside the old one some of the material was a little bit broken?
thank you for your help!
