had problem over the weekend, AA man has fitted a blank to the inlet manifold side of the EGR plumbing, the fault was 'egr valve circuit a'. to sort this out properly i am assuming a new EGr is required, but before taking out a second mortgage i would like a bit more info on the wiring and system details, does anybody have a schematic of the egr system and a wirnig diagram they could let me have a copy of.
