I know from several UK sites that there are some EGR bypass solutions around.
I haven't really thought about doing it.
I resently had my inlate manifold changed, and saw the old one. There was close to no sod or carbon build up. And that is after 204.000km. That said, I drive a lot of highway km and I often floor it. Its almost every time I drive the needle sees 200km/h or more.
That might have something to do with it... :-)
