Ewing you tried contacting via PM but your inbox is full so heres is my advice.

The valve is probably just jamed up with black carbon and yes they cane be a devil to remove.

Firstly WD40 is no good at softening the carbon - get yourself a can of carb cleaner - preferably one with a extension tube.

You'l need to remove the stop damper valve on the end of the inlket manifold and if you feel inside you'll find a connecting port which leads down to the EGR valve. If you can squirt some carb cleaner into the port and some around the outer edges of the valve hopefully that should help soften its grip.
Don't try to force the valve outwards as it likely to break - using a small punch or such try and tap it back and forth in a circular motion constantly applying carb cleaner. It took me two hours before I got the valve on my prevous LAG II to move so be patient.
