the light would only show if it was a euro4 engine.
Now you say this, but every few hundred miles the check engine light on my Mondeo ST 2.2 TDCI is coming on and the error code is inadequate EGR flow. (Previous owner put a blanking plate in)
There is NO electrical connector to my EGR, just a vacuum actuator and I should know as it has come out completely for cleaning.
here we go again! no seriously,check your hoses etc.better mpg & less smoke??? Im averaging 50 odd mpg right now with a new egr replaced,& NO smoke. Have you done a diagnostics on your car with the likes of PCMscan etc? Hows your MAF/MAP sensors? Up until a few days ago, my EGR went up,& was getting 41mpg average,and smoking like hell!. Bought new EGR(my cars is a Euro4),installed it,& my cars returning 50 odd average & 47.4 around town. and voila,car is pulling like a train,& no smoke whatsoever.took a wee video of it earlier today,but photobucket quality is crap. shows 53.9/54mpg & 60odd miles driven at 75/80mph.(had to slow down to let my passenger behind me take the video ahem).By the time I got home it was at 55mpg bang on.
If your car is smoking,theneither a sensor is boogered,or injector could be on way out etc. My point: there's a reason your car's smoking etc. get to the bottom of that problem(NOT EGR),then you wont have to blank it.trust me. Im 100% right even though some on here like to think its prudent to blank em.All that smoke' is,is unburnt fuel because there isnt enough combination of the right things to burn it efficiently.just noticed you've already blanked it.unfortunate cos now your car's not burning efficiently & you aint gonna know why. If i were you,get it diagnosed to see whats not right.
I take it,you blanked it because of smoke???
