01 1.8 EGR flow malfunction? - Boggy
Had my idle control valve cleaned out today, seems to have sorted lumpy idle and stalling at junctions, but clever bluetooth diagnostic box that my friendly (and highly recommended) independent garage has invested in printed a "tool report" saying 'error code P0400 EGR flow malfunction' - now I know the EGR valves on Mondys can get a bit gummed up, but is it worth paying another hour's labour to get this cleaned out in the same way? Is it cheap to replace as a failsafe? Or shall I "see how I get on?" Any experts on EGR valves recommend a course of action? Seems to drive OK now.
