steve67car Posted October 13, 2005 Report Posted October 13, 2005 had engine management light come on and it was shown as egr device 2 failure :lol: can anyone help enlighten me on what the hell device 2 is as i know what the egr is but device 2 has me stumped regards steve :D Quote
gregers Posted October 13, 2005 Report Posted October 13, 2005 WOT PROBLEMS ALREADY shouldve got a fockshall :lol: only kidding buddy sorry to here its playing up,cant help have no idea,but hope its not costlyregards gregers Quote

gregers Posted October 14, 2005 Report Posted October 14, 2005 mmmm how can you say that,when mines got a better star rating then yours :P :D :P :D check out auto express bout 2 weeks ago (used car survey,and the recent post here on whos mpv is better mine got a higher percentage then yours,nur nur nur nur :lol: :lol: Quote
Justice Posted October 14, 2005 Report Posted October 14, 2005 What dose the egr stand for ,Exhaust gas regulator ?I done a search on Elsawin ,Bentley manual and looked though peter russek book but the search just gave me everything relating to egr in spel;t words I need to input the full word Quote
steve67car Posted October 14, 2005 Author Report Posted October 14, 2005 exhaust gas recycle valve oh and greg wheres the zafira website for dedicated followers/drivers? :P :D :P :D :P :D :lol: :lol: :P :D :lol: :lol: Quote
steve67car Posted October 14, 2005 Author Report Posted October 14, 2005 or return valve regards steve Quote
Justice Posted October 14, 2005 Report Posted October 14, 2005 Steve ,what is the full code it is giving you Quote
Guest vr6galaxy Posted October 14, 2005 Report Posted October 14, 2005 ERG Exhaust Gas Recirculation valve, it's to do with the emmisions, a certain amount of the exhaust gas is vented back into engine to mix with the new air/fuel mix and ignited for a second time! leading to less crap being stuck out the exhaust! if you have VAGCOM you can close the valve down! this can help stop the inlet manifold gumming up! and is said to release a few BHP in the process! and reduce the amount of black smoke out of the exhaust!

steve67car Posted October 15, 2005 Author Report Posted October 15, 2005 device 2 failure hope thats a help :P for you to help me lol :D Quote
Guest marcusheawood Posted October 15, 2005 Report Posted October 15, 2005 ...so it's not to do with the emission control system then?  Nitrous Oxide is N2O, this is NOT a by-product of the combustion process, other oxides of Nitrogen are the problem! VR6Galaxy is pretty much spot on, these emission control systems do nothing for the performance or efficiency/economy of your petrol engine. Hair splitter :P Quote
Guest vr6galaxy Posted October 15, 2005 Report Posted October 15, 2005 I kept it simple :lol: to much info for some people can be a bad thing! ;) I kept the chemical analysis and the how and whys out the picture as it gets a bit difficult for some when you use big words :P Quote
steve67car Posted October 15, 2005 Author Report Posted October 15, 2005 bolx to the techi gas stuff and get back to my device 2 failure :P :P and correct me but a car does not product nitrous oxide or it would run on its own by products but thxs any how ;) :lol: Quote
gregers Posted October 15, 2005 Report Posted October 15, 2005 now that would be good 1 ltr of fuel would last a lifetimeoh did it hit a raw nerve steve :lol: ;) :P Quote
steve67car Posted October 15, 2005 Author Report Posted October 15, 2005 nah just cant stand techi bolx just to show your a smart ass ;) can be done on own with out help but on a serious not the only thing it seams to show as a fault is loss of top end other than that its fine but when the lights on its quicker? :lol: must be the nos :P Quote
Masked Marauder Posted October 16, 2005 Report Posted October 16, 2005 bolx to the techi gas stuff and get back to my device 2 failure :P :P and correct me but a car does not product nitrous oxide or it would run on its own by products but thxs any how ;) :lol: The stuff injected into car engines (along with extra fuel) is Nitrous Oxide (N20) not Nitrogen Dioxide (NO2), but a car an not run on N2O alone, you need to use extra fuel to burn along with the liberated O2 Quote
Masked Marauder Posted October 16, 2005 Report Posted October 16, 2005 Nitrous Oxide is N2O, this is NOT a by-product of the combustion process, other oxides of Nitrogen are the problem! The guy does say NOx in his blurb though. Clearly he has become confused by listening to to many street racers talking of "NOS" or "NOZ" Quote
Masked Marauder Posted October 16, 2005 Report Posted October 16, 2005 Look on the bright side though, if a car did produce N2O anyone who tried to kill themself by putting a hose from the exhaust into the car would die laughing! Quote

Guest marcusheawood Posted October 16, 2005 Report Posted October 16, 2005 Conclusion: ALWAYS be careful what you quote, someone may SOUND like they know what they're talking about when in fact all they're doing is cutting 'n' pasting someone elses mistakes! Hair commercials: 'Here comes the science part' 'I love it when they talk science' My interpretation: 'Here comes the Bullshit'  Now how in the hell would an 'Industrial Chemist' know how a car engine works?Various Nitrogen Oxides have ALWAYS been produced by internal combustion engines, it's not a new phenomenon caused by lean burn high compression multivalve engines at all! The only thing that's new are the increasingly tighter emissions regulations, which is why these engines are now used; the combustion chamber design allows for full burn (high compression) lean mixture combustion with less likelihood of 'pinking'. Do you seriously imagine that manufacturers would increase mechanical complexity (and therefore costs) unless regulation FORCED them to address these issues. This is how 'chipping' a car works by reducing EGR control and increasing fueling and ignition advance. Economy and emissions are where it's at for manufacturers of volume motoring.

steve67car Posted October 16, 2005 Author Report Posted October 16, 2005 been interesting :rolleyes: but as always some one buts in with someone elses bull/bolx and as always the real thread is pushed aside so we go from egr failure on device two too holy cow your car produces noz/nos :) so can we get back to DOES ANY ONE KNOW WHAT DEVICE TWO IS ON THE EGR many thx to all that have inputted :) many thx steve Quote
Guest vr6galaxy Posted October 16, 2005 Report Posted October 16, 2005 To my knowledge there are several main parts of the ERG system, the ERG valve, the solenoid that operates it, the pipe from the exhaust manifold, the exhaust gas cooler and the pipe to the intake manifold, then there are several sensors and vacuumme pipes that control all the above! so no! I aint got a clue what device two is :) I just answered another posters question so dont start on me as I know where you live :rolleyes: :) Quote
steve67car Posted October 16, 2005 Author Report Posted October 16, 2005 sarky b'stard :P :rolleyes: ;) thx for your two pence worth [or not in this case] lol :o :) :) Quote
