EGR valves...... who has theirs blanked off? Had mine blanked off on my 2010 Citroen Dispatch 1.6 HDI. Had a new one on in October and it failed again last month!! Everything I've ever read about these wee blighters is only negative & when you understand what they do that's no surprise. My van has smoked under acceleration since I bought it, not unknown for Diesels I know but this was excessive IMO. Anyhow, had the EGR blanked off last week & the van is like a whole different beast! Better pull away, smoother power, slightly improved MPG & No smoke- I can't even force it to smoke!! It seems a common modification to make so I just wondered if anyone here had done it?
