Managed to get it off, had a look at it and it appears to be ok ?? valve moves freely by hand and operates ok with 12v to it.
I've had a 'search' on here and the EGR's appear to give problems, i know its kinda spring loaded to keep it shut but whats the actual fault with them ? do they just kinda jam shut or do they get jammed open ? I'm thinking they jam open as folk say to blank them off, if they jammed shut then they wouldn't need blanking off ?
Anyone shed some light ??

EGR valves on a x14 are shit mate. they get coaked up and ether jam open or shut as you said... might be with checking your lambda/hego sensor aswell, as if im right (correct me if im not peeps) you can get EGR codes if the lambda starts to go down, and it wont show any lambda codes, and it will cause the car to run crap due to it switching the mixture to lean and rich all the time.

egr valve is to keep cylinders warm as an emissions device nowt really to do with mixture the valves knackered mate probs better off biting the bullit and getting a new one if you balnk it off and the 14 or 16 you will get a map sensor fault due to the drop in pressure when valve should open. been here loads of times at work pal its a whole lot easier to buy a new one

Fitted a new EGR yesterday, for some reason it now idles at 3k revs !! Checked all vacuum pipes (replaced a few of them) but cant find any leaks or owt.
Starts and drives ok without the ECU light coming on, but still getting fault codes flashing up, see here ... http://www.corsasport.co.uk/board/viewthread.php?tid=427319
