Unplug EGR valve

So I found out that it was my EGR valve that went instead of the EGR cooler...(yes, im new to diesels)

I have read some things on the internet about people unplugging their EGR valves...

Will this hurt the EGR cooler/system/engine in any way other than a CEL???

it helps, this is not a fix but this does help I wish I knew about this when I first got the truck, would have helped mpg, temps, longevity. mpg gain is minute, unnoticeable

I've had mine unplugged for 30,000 miles on my 2003... no check engine light. Apparently the newer trucks will turn on the check engine light if you do this.

1991 Volkswagen Jetta 1.6TD ECOdiesel -- 423,000 miles
2003 Ford F-350 6.0 -- 131,000 miles
1987 Mercedes-Benz 300SDL -- 307,500 miles

2000 Volkswagen New Beetle TDI (RIP)
1987 Mercedes-Benz 190D 2.5 Turbo (sold)

It won't hurt it!!!
My EGR valve has been unplugged for the last 2 years and the only drawback is the CEL staying on.
