I've been dealing with mine recently CAPA engine.
There is a motor driven valve which controls the flow of exhaust gas and a solenoid/vacuum pusher that controls the path of the gas through the cooler (or not).
They are a lot of work to get out but you can get to the front of the EGR valve a bit easier and get some carb cleaner into it.
You need to take off the inlet piping, which will mean taking off the high pressure fuel lines from the pump and a few other bits and pieces, then you can undo the braided EGR pipe and clean the valve from the front and from the top by removing the plastic cover containing the motor and pot connections.
Removing the entire valve and the cooler it quite a bit more involved.
