The EGR valve is the silver object towards the front of the picture with a plug on it and a silver tube coming off the right hand side. Pretty easy to remove. Start by disconnecting the electrical plug, then remove the silver tube on the right by. Then below the EGR valve is a rubber hose, remove this if you can (use a rag to then block the hole where the hose goes to stop you dropping anything down there)
The EGR is held on with 3 star drive bolts. One at the front and two on each side, these can be fiddly to remove but not impossible. Also disconnect the dip stick tube from the side of the egr.
where the metal tube on the right was there should be a cover plate held in place by two screws, remove this and take that part out to clean it. Mine was caked in carbon. You should be now able to clean your valve up. Good luck, it didn’t work for mine and I still have the same fault so fingers crossed for you
