Egr worked splendidly and managed to kill the motor at idle during the test. The gasket was indeed the problem. Thank you for saving me from a stupid purchase!
The DT egr cutout in the flange looks huge. No way does it need to be ground like 4crawlers LCE header. I probably didn't even need to cut the gasket but I did for good measure anyway.
