    I'm trying to do the same on a Kangoo but at the moment no success. I couldn't find anyone who knows how to do it on this ecus. I'm doing some tests but by now Delphi wins me :-(
    Good luck !

    This is not an original file if you look at address 00C270 x 256 points the value is equal to 8000 decimal, this is the closing value of the maximum of egr .. therefore in this way the valve egr should already be in a position off ..

    What dtc code do you get in diagnostics? Maybe try to disable dtc, but i've never done this on these type of ecus...

    That's not true: this is an original file sure.
    The question is that this engine don't have MAF sensor, and this is the reason why the Air Mass value map is all at 8000.
    EGR disable should be done through any "Switch off" point or map, which are not easy to find in general.
