Help Please - Signum 1.9 cdti 120bhp

**T111mts** · 16th February 2013, 22:06

Hello,

1st fault was no power under 2000 revs.

cleaned EGR valve - improved slightly
unplugged EGR valve and improved even more (At least it drives now)

However, I still have very little power under 2000 revs and my MPG is terrible (20mpg on motorway runs)

I have checked the pipes and they don't seem split?
What other pipes should I check?

Could it be DPF?

Please help!!!????

Thanks for post.

checked both links and they relate to EGR valve.

I don't think it's just the EGR, as when I have unplugged it the car still has no power under 2000 revs.

I have completely stripped the EGR and it still runs like poop!

does any one have any other ideas?????

Also, how would the car run without the EGR plugged in?
