It's been discussed before if blocking your EGR would cause problems with Aircare. I just passed aircare with my non-existant EGR Delica and no problems at all... good to know. Here's 2 way to block your EGR. (you can try other ways by blocking the vacuum lines but I'm not convinced of the results).
You can either use a thin metal plate shaped like the gasket but without the hole in the middle. Thickness should be about 1/16", just replace the original gasket with the new blocking plate.
The other way is more work but I like it better. You completely remove the EGR and block both openings. The one on the intake manifold can be blocked with a 1/2" or 3/4" plate of aluminum (you'll need shorter metric bolts to replace the original longer ones) and the bottom one on the engine block can be blocked with a steel plate of the same width as the original bracket (I think 1/2" as well). Just make sure your gasket on the engine block is still good... You can re-use the original bolts for that one.
That's the way I've done it on my white van, it's more work but then you don't have extra parts just taking place... On my low roof I've simply blocked it. Both ways will work the same.
And here's a picture taken by Fexlboi that shows the elbows leading to the intake manifold. That pictures is a good enough reason for me to ditch that EGR! I'd rather have a cleaner engine by removing the EGR than looking at that picture!
