I think there it is a leak, the same message has come up again and i have noticed some black residue on the garage floor underneath the front of the car in the middle, where she is kept most of the time. Is that where the egr valve is ?
Thanks Howey no errors reported from the MAF but a change is in order.Its the MAF which reports demand so should the egr take more or less percentage of air intake it calculates the egr is either taking too much or too little
Thanks again, I do seem to remember that VCDS did mark up something about the MAF values but I passed it by. I will give the car a full scan with my registered version, and if it flags it look into the results. But I am leaning towards the MAF reporting wrong as the EGR was clean when checked as opposed to the throttle body and adapter plate. Any change will be like for like ie Bosch.The maf will report egr faults as it knows if the egr is not taking its fair share of the intake air upon different opperating conditions, in my experience when a maf is faulty it causes hesitation, values can be checked with good diagnostic kit and changing it wont hurt (so long as a quality unit is fitted) i wouldnt go changing it for the sake of it as failure appears quite low
