    Question EGR valve insufficient flow

    Guest-only advertisement. Register or Log In now!
    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?

    Given that you've got a TDI, not many people here are going to know much abotu this. Maybe some who knows a bit about the TDIs can chime in though.

    Yea. Sorry we're totally unhelpful. Audizine is mostly North Americans and we weren't blessed with any TDI Audis until very recently.
