"Computer" is a misnomer. The EGR box isn't smart enough to be called a "computer." The air box has a flap with a potentiometer that tells EGR how much air the engine is sucking in. If you have EGR defeated (and even if you have not) it is unlikely to make a difference if you remove it. You cannot completely remove all of the EGR electronics because the tachometer signal runs through the electronics.

A number of W124/OM603 listers have removed the air box and replaced it with a pipe. This action alone reduces the car's weight by more than ten pounds. Whether the plumbing in the SDL is the same I do not know.
