As said you can't change EGR stuff via VCDS in PD engine
you can in old VE engines
there are guides of how to code out EGR on winOLS mapping software which you can do yourself.
then again most places would do it very cheaply, if you have it remapped already why not ask them if they can map out the EGR....
you can drive it with the EGR fitted and it won't damage anything and you won't gain any power from the map, you just may get the warning light.
