    im pretty sure this isnt a vcds thing - its coded within the ecu programming and needs a remap to remove the function, along with a physical blanking plate - thats certainly the case with later PD cars that ive had

    On the Ross-Tech site (TDI VCDS Info) there is a coding value to change the valve duty cycle, effectively turning off the EGR. The value given doesn't work for the 2.5 V6 TDi, but go for the highest value possible.
    The login code for the AFB engine is 26242, not the value in their example.

    See Engine Adaptions Login for my inputs
