    Hi

    I have a 2004 Audi A3 8P chassis with 83k on the clock.

    I have the following DTC error:

    1 Fault Found:
    16785 - EGR System: Insufficient Flow
    P0401 - 000 - - - Intermittent
    Freeze Frame:
    RPM: 1575 /min
    Torque: 44.0 Nm
    Speed: 55.0 km/h
    Load: 10.6 %
    Duty Cycle: 14.7 %
    Bin. Bits: 11000000
    Mass Air / Rev.: 315.0 mg/str
    Mass Air / Rev.: 535.0 mg/str


    Yesterday, I removed the EGR valve to find it was really thick with carbon therefore I gave it a good clean almost like new and put it back on again. I thought this would fix the problem, however today I have got the above DTC again. Does anyone know what else could be causing this? Or should I replace the EGR valve now as cleaning it didnt work. I have not noticed any permormance issues with the car, could this be a false alarm or faulty wiring somewhere?

    Also, can you recommend a good dealer to souce parts from (Apart from Audi..) I've been looking at Euro car parts for an EGR valve for £73. Anyone know any other good sites?

    Any advice would be appreciated.
