Sorry been away pretending to work, Yes as clutch said as its got a sensor it will bring it up. It's either a faulty EGR or faulty sensor. What makes you assume its the EGR? Also slightly off topic does anybody know the connection type on the corsa B for an OBD 2 unit?
Was talking on here and a few people suggested it was the egr valve and after reading up a bit it does seem like the likely cause of the problem. Just the EML hasnt come on thats why I was a bit confused.
As said the Port may be blocked so the valve will still open but the gasses can't escape...so the sensor won't show a problem with the EGR valve but you won't get the recirculated gasses. It could alternatively be the thermo vacume valve no working properly. I'm unsure if that has a sensor on it?
Yeh that's probably exactly it it needs a clean. Just because it's dirty the mechanism is still working (so not setting off alarm bells with the ECU) but your getting no effect from it. 1st step would be to clean it up and see how it goes. Maybe deatschtye can either confirm or dispute that theory when he sees this.
i'll agree with you mate, if its dirty then the valve can stick slightly in it's slide which makes it slow to react wether its a solenoid or a vacuum type (although vacuum types tend to stick solid). it's always a good idea to keep these lil' buggers clean because it can cause endless problems when they do go wrong and cleaning them often (say per service) can help them keep fairly reliable. a quick inspection after you've cleaned it is always a good idea too to check that it's not faulty or going to fail anytime soon.
