    Caddy SDI 2.0 EGR problems with diagnostic info added..........help still needed ;-)

    Hello to all, I have a reoccuring code as shown below.

    16787 - EGR Valve [N18]
    P0403 - 000 - Malfunction
    Freeze Frame:
    RPM: 840 /min
    Torque: 68.3 Nm
    Speed: 0.0 km/h
    Load: 0.0 %
    Duty Cycle: 18.7 %
    Duty Cycle: 94.8 %
    Absolute Pres.: 877.2 mbar
    Temperature: 14.4C

    The van is lumpy on tick over, especially when cold.

    I have finally managed to get around to playing with VCDS and getting some screenshots online. Hopefully some one might be able to point me in the right direction for diagnosis of the problem.
    The EGR has been replaced with a new unit. The EGR control Solenoid N18 has been tested with a replacement and no change.
