If you can get that big nut on the EGR pipe off, remove the EGR, then remove the 3 screws holding the nozzle into the intake manifold. From here you can inspect the down pipe, valve and nozzle.

if you have an ohm meter, measure the coil resistance of the solenoid. If its infinites, the coil driving the valve is bad. I'd guess its 150 to 50 ohms but need to find the spec. I might be less. Next, using small gauge wires power it up and listen for a click off and on with the car off. It should throw a tiny spark. very tiny. If nothing, a good sign its burned open.

The other option is to take off the manifold. Only takes about 25 min.
Here is what your looking for. Sorry - don't know who to give credit too for pic...
