Don't have to delete anything, just make a sheet metal gasket with no hole for the exhaust to flow through. It's all there and still "working" as far as the ecu is concerned.
EGR on diesels is known for increasing tail pipe soot, decreasing fuel economy and decreasing horsepower.
With this mod you can try it and if fuel economy goes down you can easily undo it. Also I have heard of 1.9t intake manifolds becoming horribly clogged with diesel soot.

On a gasoline engine the EGR being disabled usually decreases fuel milage. It does not effect peak power because the EGR closes at around 1/2 throttle.

I don't disagree with anything you say, but removing (or modifying) working emissions equipment from motor vehicles that travel on public roads is a Federal crime in the US, and they are cracking down on it. If I did do something like that I would not post about it on a public forum, doing so could get the forum in trouble.

Now, I will say that when my Passat is not driven on a public road, the EGR is turned down to the minimum using the VAG-COM so that soot is not clogging up my intake manifold .
