Is your car edc15 or edc16? What year is your vehicle?
EDC15 you can change the values in the EGR maps as descibed above.
If it is EDC16 you have to put the EGR hysteresis maps to Zero (which is totally different) If you just put the EGR maps to 850 or so you may get the MIL light come on (EDC16 with MAF sensor etc)
Please post your binary and I will let you know which way you need to do it. I can also do it for yor and post your file back if you want (free)
