ANGELFIRE1 Posted February 12, 2018 Share Posted February 12, 2018 Blank it off ..emission control on diesels is a joke ..egr valve , particulate filter etc, in my experience are a licence to print money not save the planet! Aye, but it was an EU directive, so we implimented it without even a wimper. Angel1. Link to comment Share on other sites More sharing options...

My car is a 2007 1.6 hdi so its an older model do you think that the engine management light will need re programming . Link to comment Share on other sites More sharing options...

I have read that it makes more smoke, so I am glad I am not driving behind it. The newer the car, the cleaner the emissions. Link to comment Share on other sites More sharing options...
carosio Posted February 12, 2018 Share Posted February 12, 2018 Tried it on my elderly VW 1.9TDI, couldn't really tell much difference, but pressure built in the cooler pipe and caused an oil leak, so removed the plate. Never had an engine light come on, must like all the veg oil it runs on! Still on the original exhaust after 17 years. Link to comment Share on other sites More sharing options...
mafya Posted February 13, 2018 Share Posted February 13, 2018 But if the MOT rules are being made tighter, will it fail because its now non-standard and may fail its emissions test? ---------- Post added 12-02-2018 at 19:32 ---------- Completely blanking the EGR will most likely cause the EML to come on, this will now cause an MOT failure, under the new rules. ---------- Post added 12-02-2018 at 19:41 ---------- Is section 12 the relevant section, I an trying to find out what these new rules are. The link says 'draft'. https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/671818/mot-inspection-manual-for-classes-3-4-5-and-7-from-20-may-2018-draft.pdf You can blank off an egr valve without it being obvious and for the last 6 years my transit has passed its mot test no problem. Blanking the egr valve throws up the eml on some vehicles and not all of them. ---------- Post added 13-02-2018 at 06:30 ---------- Has any one any thoughts if it is worth fitting a E.G.R. valve blanking plate on 1.6 h.d.i diesel Citroen.

Guest Posted February 13, 2018 Share Posted February 13, 2018 You can blank off an egr valve without it being obvious and for the last 6 years my transit has passed its mot test no problem. Which is fine but the point being made is that the regulations are changing this year so it may not any more. Link to comment Share on other sites More sharing options...
blackydog Posted February 13, 2018 Share Posted February 13, 2018 No it won't..... Expert are you... EGR (Exhaust Gas Recirculation) valves recirculate a portion of the exhaust gas from the engine (5% to 15%) back into the combustion process. This ensures that the fuel gets completely burned while decreasing the production of harmful gases such as nitrous oxide. Link to comment Share on other sites More sharing options...
Obelix Posted February 13, 2018 Share Posted February 13, 2018 I don't know about the Citroen but I did it to the two Discovery's we have had, and it did make a noticeable difference. Both were quite old and a bit "gummed up" with years of breathing exhaust gasses. They were an idea of the EU I believe, a total waste of money. The ICE engine requires fuel and clean air, not some of an engine's exhaust gas. Angel1. Oh blame the EU for not maintaining your car hmmm...? The reason they "got better" was you stopped leaking exhaust gas through the gummed up valve when you shouldnt have. If you'd fitted it with anew valve or just cleaned the old one, then you would have seen an even better response. EGR valves are proven to reduce NO2 emissions. Imagine that. Something that has almost no cost and reduces pollution - yet you decide to turn it into an ill informed uneducated whine about the nasty lot in Brussels, who I dont think ever mandated they must be used.... But hey it's something you dont like - lets lie and blame the EU! Link to comment Share on other sites More sharing options...
alchresearch Posted February 13, 2018 Share Posted February 13, 2018 Its a very popular and easy fix. The 1.6 diesel engine in Pugs and Citroen's benefits the most, especially in curing that 1800rpm hesitation bug that plagues these engines. Sadly, a new EGR valve won't sort it. But don't do it if your car is running fine. Link to comment Share on other sites More sharing options...
