The hardest part on removing egr is the cat but once you got the car up in the air (on axel stands or ramps) it's not to bad looks worse than it is

Maybe the easiest for you would to pull egr pipe off and blank it off as a quick fix

Ive put a blanking plate inbetween the egr valve and the pipe to the exhaust manifold but it made no difference.

Looks like it's time to take egr off and give it a good clean

if the egr is blanked off, then its been disabled, so in theory taking it off and cleaning it is not going to make any difference???

could be wrong tho....
