Sorry, another EGR question

[Mat Johnson]

So there I was, chugging away reading lots of posts about this EGR valve and how turning it off helps improve MPG, and I thought "I'll have some of that". Armed with a pair of pliers and a cable tie I pop the bonnet and find..... its already done. Guess I won't be getting any increase in MPG after all.

Anyway, to my question. I've read some different opinions on how this can and cant affect the way your engine runs, but can anyone tell me if it can affect exhaust emissions? My mot isnt far off and I don't know whether its worth putting it back as it should be in case my emissions are up (if you're not burning off more of your emissions surely youre shoving out more nasty stuff), or whether we dont test for the gases that increase (I read that in one post). Could they fail it on the fact ive disconnected it?

Maybe there should be a sticky thread on this?

Over to you lot.....

bung some injector cleaner in the tank, and drive it like you stole it! never known to fail... no need to reconnect the egr for the mot either. (using veg oil also cleans up the emmisions, but dont forget to pay the tax on it...

When your fuel gauge gets near the empty mark, chuck a full bottle of Redex in the tank and drive like Chillitt says for about 15 miles then top up with diesel and you should notice less smoke and a bit more get-up-and-go.

Also. remove the black plastic tube that goes from the air filter to the turbo and give it a clean out, as theres probably oil deposits in there.

The EGR is mainly to reduce the NoX emissions, which isn't
part of the MOT test in this country anyhows.

vince do you put all of that size bottle in ??

[BUSHWHACKER]

Yup! 500mls into a near empty tank, goes like the clappers!!


p.s. when I say nearly empty, I mean just before the fuel light comes on, 'cos there's about one or two gallons left in the tank by then.

how do i find out the easy way??

Well, the sender unit is at the front of the tank, so you could run the tank quite low, and drive up a long steep hill??

My fuel light has only come on twice and each time was at that, "There has got to be a $$$$ing garage round here somewhere," moment. I was impressed with how far I went after the yellow light came on.
