Earlier models had two valves, one for EGR one for turbo.
They are identical so could be swapped for diagnosis.
2011 has one only, for turbo.
DIY is simple. Just remove anything in the way and
solve the problem of accessing the lower of the two mounting nuts. I remember this being very awkward.
From my Ford dealer reciept:
Ford FO- 6G9Q 9E882 CA VALVE EXHAUST GAS RE $105 (recirculation probably)
Good luck.
