How to fix a E.G.R Valve?

What is an E.G.R Valve for an vauxhall astra 1998
Iris, February 2009
The EGR valve is part of the emmision control system it puts some of the exhaust gases back into the engine to burn up any unburnt fuel vapour in the exhaust gases, and so they can get "sooted up" you can remove the valve and clean them with a spray carb cleaner
