Many at
Fred's TDI Page. TDIClub.com. VW TDI Enthusiast Community have tried this.
The only positive is a slight top end gain.
One (don't remember who) drives long enough to eliminate the warm up issue.
Why are you wanting to delete it ? Intake/intercooler restriction/crud ?
Changing the PCV to vent into a can instead of the intake will nearly eliminate the intake crud. With no oil to stick to the EGR soot just goes right through.
YMMV
