I've got an 06 Mondeo TDCI 2.0.
I've recently blanked the EGR valve due to filling my rear view mirrow with plumes of smoke. Since blanking the EGR the plumes of smoke have stopped except for a small amount if I really boot it which I assume is pretty normal for a diesel.
As mine isa euro 4 spec the EML keeps coming on and I keep resetting it. I'm wondering if I change the EGR for a new one will the heaving smoking return or was it likely it was smoking as the EGR wasn't shutting/working correctly?
I have checked the main air hose to the intercooler and it contained no splits (yes it was removed for checking). Could any other hoses be contributing to heavy smoke now the EGR has been blanked or was it likely the EGR was the main cause of this?
I'm just trying to get to the underlying problem. I know most will say to keep the blank in but I like things right. I see many other Mondeo TDCI's around that don't smoke.
