Has anyone blanked the EGR valve? Any problems doing so? Warranty issues? (remove for service then replace?) I bought a 60k Freelander TD4 a while back and the CRAP I had to clear out of the inlet manifold was horrible. An EGR blank, a really good clean and new turbo pipes and it runs like a dream now. If I do it now on the van it will surely keep everything clean, including the turbo?
