Does anyone know when the EGR was introduced to the VW engine.

Have had a few people say to me I should be doing something about blocking
it off to reduce damage to the motor. Had a mechanic say:
"Most modern diesels with EGR will get through the warranty period (just) before failing due to EGR. "

Does anyone have a high mileage vehicle which has the EGR.

Been some good threads re: the EGR and would seem 3 options. Block it off,
Vag com to increase air supply or the provent option.

So any chance some of our more experienced guys can give us their views
on this issue. Should we all be more concerned with these newer diesels especially regarding the EGR.

Thanks guys
Neil.
