Thought I'd pass on some info for those thinking of replacing the EGR bypass with a kit. I removed replaced mine a couple of weeks ago in my D2 (2004). Whilst the change is not dramatic, it is certainly an improvement and worth doing IMHO. Its not so much that you have a lot more grunt at take off (which you don't), but that the whole thing is much smoother and responsive with much less turbo lag. Takeoffs now are much easier, especially on hills.

Going on hols for a couple of weeks - happy New Year to all my fellow Disco lovers.

Cheers
