michaelhayler17 Posted May 18, 2015 Share Posted May 18, 2015 Ive fitted an EGR plate to my car and was "aware" that an engine management light would come on. Just to make sure with those that have done it, it was this light that comes on yes? Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted May 18, 2015 Share Posted May 18, 2015 Yes, the amber engine shaped light, you need to check the resultant code to make sure it's the E.G.R.V. & nothing else. 2 Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted May 18, 2015 Share Posted May 18, 2015 Out of curiosity why did you blank it ? Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted May 18, 2015 Share Posted May 18, 2015 Better mpg & sometimes better low down torque. & if the valve fails they cost a fortune to replace Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted May 18, 2015 Share Posted May 18, 2015 Rare / unusual to blank on a petrol engine ? Quote Link to comment Share on other sites More sharing options...

MONDEO TXS 2.2 Posted May 18, 2015 Share Posted May 18, 2015 Better mpg & sometimes better low down torque. & if the valve fails they cost a fortune to replace I know of the benefits on a diesel , but on a petrol engine ? Yes, E.G.R.V.'s aren't cheap ! Quote Link to comment Share on other sites More sharing options...
michaelhayler17 Posted May 19, 2015 Author Share Posted May 19, 2015 Yes, the amber engine shaped light, you need to check the resultant code to make sure it's the E.G.R.V. & nothing else. i got P0400 exhaust gas recirculation "A" flow on the code check. Seems pretty self explanitory! Gotta get it mapped properly so it can b removed. 1 Quote Link to comment Share on other sites More sharing options...

Yes, E.G.R.V.'s aren't cheap ! so far its only felt smoother, alot less hesitation. Plus a tiny tiny bit more poke goin up hills... but nothin to shout to much about.

iantt Posted May 19, 2015 Share Posted May 19, 2015 Trouble is with blanking egr on petrol it increases combustion temperatures. Egr dont block up like on diesels. Quote Link to comment Share on other sites More sharing options...
michaelhayler17 Posted May 19, 2015 Author Share Posted May 19, 2015 Does it really? See theres so little information out there about it, it was a case of lets see what will happen. Do u know this for sure? Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted May 19, 2015 Share Posted May 19, 2015 It's a fact. Happens on diesels too, but diesels benefit. Quote Link to comment Share on other sites More sharing options...
iantt Posted May 19, 2015 Share Posted May 19, 2015 Does it really? See theres so little information out there about it, it was a case of lets see what will happen. Do u know this for sure? yep high combustion temps creates higher nox, thats why exhaust gases are introduced at part throttle, reduces the nox by cooling .sounds daft by putting hot gases in but it does cool, to understand egr valves for the non tech, just wikipedia it.

michaelhayler17 Posted May 26, 2015 Author Share Posted May 26, 2015 So in conclusion all ive really done is set my car up for a future MOT failure? So why does this benifit diesels more than petrols then? And how do they not fail there MOTs as a result? Quote Link to comment Share on other sites More sharing options...
iantt Posted May 26, 2015 Share Posted May 26, 2015 What makes you think it will fail mot, egr blanking or engine light on not a failure, as for emmisions , mot not interested in nox readings diesels suffer more due to sooty gasses being passed through egr, this sooty carbon oily muck builds up on egr valve its self either blocking shut or more likely open,.

michaelhayler17 Posted May 26, 2015 Author Share Posted May 26, 2015 So the NOx reading is not part of the emisions test? Ok that'll b fine then. So it benifits diesels more cause of the fuel they burn is dirtier than petrol and stoppin those dirty gases makes for cleaner air for combustion?

MONDEO TXS 2.2 Posted May 26, 2015 Share Posted May 26, 2015 The E.G.R.V. & D.P.F. on a diesel are only there for E.U. emissions claptrap, both devices strangle a diesel engine. Quote Link to comment Share on other sites More sharing options...
