I think I have laid out my case in other threads, but I wanted to test the effects on fuel mileage, and it looks like it has a negligible effect on the ALH TDI. EGR deletion improved the fuel mileage on my Jeep Liberty CRD, and those had a high rate of EGR valve failures as well, so it made a lot of sense for that vehicle. The TDI, apparently not so much, but it will reduce intake clogging and may also improve CO and particulate emissions.
