So today with a day off I took the opportunity to clear out the Mondeo's EGR valve, which as the years go by builds up a thick coating of carbon that slowly begins to affect the amount of air the engine can suck in easily. This eventually effects the fuel economy and low-down power of the engine but will never get so awful that bad things happen.

Nevertheless, following this handy guide I had it off, cleaned, and back on in just over and hour and a half all in. Check out the before and after shots I took.

A vast improvement in the cleanliness and over the next hundred miles or so the engine will adjust to it's new vast improvement in airflow.

It's a shame that the weather turned in the afternoon because I was planning on also taking the inlet manifold off and giving that an equally good clean.
