I was having problems with my dpf.. was doing regen at the wrong times. High revs at idle, smells strong deisiel fumes.. cannot accelerate sometimes until at 3000rpm. Coil light come on occasionally but it's never gone into limp mode. I ham a dpf delete and remap and I'm still getting the same issues.. is it possible for the light to come on still.. could his delete map not work?? Its not showing any error codes. Could something else be wrong? Its 2007 seat leon tdi fr
