Egr help

[dieseltech24179]

Ok so I understand how to take off the egr the posts that I read about that was good but when it came to blocking off stuff I didn't understand which holes to block. And lastly if I remove that will it kick on the engine light and my charcoal canister has been removed and idk if it was removed correctly this was already done when I bought the car. Could anyone help make sense on wat to plug up or leave unplugged on that. Any advice would be greatly appreciated thanks!!
