    Hi all

    I took my car to audi to get a diagnostic check done came back as egr valve insufficient flow.
    Bought a new siemens EGR valve and I am Still getting the same fault code
    The pipe feeding the egr valve has slight oily/sooty coating on the inside which can be wiped off with your finger. No blockages in the pipe.

    What else could cause this fault?

    if it's the siemens electric valve rather than the vacuum operated i think you need to use 'adaptations' in VCDS to set it up. I could be wrong though.

    Thanks for the reply

    How do you test the egr cooler is working as there is a actuator mounted on the end of it?

    Presume you mean the EGR valve having an actuator on the end of it? - you need VCDS and use 'measuring blocks' to check it's functioning. Maybe you need to take it to a garage to get it checked / set up.

    On the end of the egr cooler there is a actuator to direct the exhaust gasses through the cooler when required.
    How do you test if it's working
