Default effect of grinding EGR valve in diesels

Since black smoke was coming from the exhaust of my diesel verna, i went to the dealer to get it fixed.

First they drained out all the fuel and put in fresh diesel suspecting that the diesel was adulterated. However the smoke did not go away. Next they ground a few mm from the EGR valve. Apparently this increases the ratio of fresh air v/s exhaust air coming into the diesel engine. This solved the problem of excessive smoke.

Googling for effect of doing so, I found that this will
- result in higher engine temperature
- more N02 emission
- may affect life of catalytic converter

Anyone did this to their diesels? did it cause any adverse effects?
