Ive always thought that its important to keep the inlet system clean and smooth
to get the best cyl filling possible, especially on a diesel, where one is always looking for the max amount of clean cold air getting into the cylinders?
Any thoughts or advice welcome.

We only get the VAG passenger diesels here in the states but from what I have read, the clogging is most noticeable when you are trying to flow a lot of air or make a lot of power. You may not be losing much efficiency at light or part throttle driving.
Do you have any data about your mileage gains without EGR? On the VW blocking off the EGR confuses the computer and many report decreased mileage.
