I'm a little confused about your post but I will tell you what I know about keeping or deleting the egr.
if you keep it you need the valve, sensor, and the vacuum hoses that run to both. You also need to connect the egr tube to the valve.
If you delete it you only need to take off the egr tube and plug both holes on each end, cap the hose off on the sensor, keep the hose on the valve. This way is the way to do it without buying a performance chip. It WILL throw a CE code but it doesn't hurt anything.
If you do get a performance chip for it, you take off the egr tube and cap both ends, take off the sensor and hose completely and leave the sensor harness just sitting there, take off the valve and get a delete plate that screws into the two bolt hole locations, plug the hose off at the little tree it goes to on the firewall.
Hope this helps you out some.
