From the description for the code.. could be an electrical connection to the EGR valve.. could be a circuit issue. Where I live I've had problems with mice getting under the hood.. they can chew wires and hoses. Chewed through a vacuum line for the turbo on one of my cars. It is also possible it's an erroneous code. I once got a CEL on a vehicle that indicated an issue with the automatic transmission... Problem with that: it had a manual transmission! Thankfully it was cleared and has not returned! These cars have considerable on board diagnostic capabilities, but as with the average PC.. sometimes they do also have glitches.
