EGR Vacuum Regulator (EVR)

Yours is leaking. Reread section 47. The sponge filter is only there to allow the EGR to leak down when the EVR is de-energized. Your "small leakage during valve closed tests" is a little too much. You might be able to reduce it by removing the valve & tapping it to free up the solenoid at the bottom of its travel & reseat the pintle.
