Any advice on how to remove EGR? (W211 2.2)

I've had a look at the MAP and MAF sensor for this car and I'm pleased to see everything looks ok. Well no oily deposits appears clean and dry.

I'd like to take a look at the EGR valve but after detaching the multi plug and removing the two TORX bolts I can hardly shift the thing. Best I can manage is a few degrees to the left.

Does anyone have any useful tips on getting this valve out?

Thanks.
