IF I had a registered copy of VAG-COM (not the freeware version), I could reduce the EGR but not eliminate it. Judging from the actual MAF values without EGR and what VAG-COM allows you to reduce, all you can do is cut the factory flow by about 40%, 270mg/stroke to 370mg/stroke, and full flow (no EGR) measures about 480mg/stroke. US spec'd EGR flow at idle is truly excessive and ridiculous.
A tuner may be able to reduce that value more so you don't get the CEL, but I don't need a tune and my vehicle is staying factory stock for all outward appearances. A tuner cannot technically remove the EGR either, the vehicle owner/operator must take responsibility for that.
