Removing EGR Valve - Defender 90????

Hi all,

Ive got myself an EGR blanking plate and the steel tube bit to replace
the actual valve.

2 Questions if I may:-
1. How the hell do you get the 2 alan studs out of the
manifold, especially the lower one?? Mine seem to be VERY tight - I
really dont want to have to take the manifold off to get better access
to them.
2. Does the blue pipe (wire?) just pull off the top of the
diaphram on the EGR valve or off the sensor thing thats bolted to the
wing (the other end of the pipe)?

Any advice welcomed!

Thanks
Jon

Forgot to say its a TD5, not a 300Tdi...
