There are threads on how to bypass or remove the EGR. I have mine bypassed for "testing" until I get a blocking kit for "testing".

13 VW JSW 2.0 TDI 193K, Tuned with DPF and EGR Delete.

91 W124 300D Turbo replaced, Pressure W/G actuator installed. 210K

90 Dodge D250 5.9 Cummins/5 speed. 400K

So I should cap both the line going to that bolt (is there a name for it???) and the one going to the egr?

I'm still trying to figure this out...

You can plug all the lines connected to the EGR. Then follow those to the black box, remove those. Any vac lines going to the driver side connections can also be plugged off.

I believe you. I do. And I will. But I still can't bring myself to do it until I know why they are there in the first place and why I want to bypass it all. I guess I should know but I don't. Thanks for the knowledge.

Emission controls for the EGR.

Removing them will get you a cleaner engine, better running quailty, better MPG and slightly more power.

Yes, it is designed to reduce pollution by redirecting exhaust gasses to be re-burned. Internal combustion engines like relatively cool oxygen rich air to burn instead of hot carbon monoxide.
