"Jumping on it" is a good idea every once in a while as long as the engine is fully warmed up. It might help a little, but not much. The reason why is because it burns up and blows out the exhaust side but it doesn't do anything for the gummed up intake side.
The EGR is partially open except when at full throttle, at full throttle it closes, but it also closes when the car is off, so the EGR moves plenty when you shut it off.
I think vacuum lines is possible. There might be a vaccum leak or a bad egr solenoid or bad egr valve which causes the "EGR system exceeded".
