As said above if you want you can remove that whole egr tube adapter if you remove the egr valve first... It will just slide off exactly the same way that the egr valve does. You may have the same issue with those nuts/studs as well though.
Only warning I have is that I could not buy the gasket that goes under that adapter locally. Luckily mine was in good shape so I re-used it with a little bit of copper gasket-maker. No problems yet. All other gaskest (egr tube and egr valve) were available over the counter.
It's nice to see a neighbour on the boards (maybe literally?)
We're in the same town lol.
