My model year 1990 is when MB put the M104.980 engine in 300CE, I had a 1989 300CE with M103, which I don't remember where its egr is located.
I was trying to remove the EGR valve to test but unable to, it is mounted on the rear exhaust manifold and the is no room to remove the rear nut with not more than 1 inch clearance. I think it can be done only with special tool.
As the picture shows, the wrench when going over the nut is already touching the engine block, no room, not 1 cm to wiggle.
