I just had a follow-up thought regarding removal of the egr valve. Since my re-manufactured MB engine is under warranty for 50,000 miles or 48 mos., will I be voiding the warranty by removing the egr valve? Would I be better off leaving it plugged as is, and if any warranty problems unsue, just unplug the vacumn line before having the MB dealer service it for a warranty prooblem?
