Check around the EGR (the bit just to left of plenum) for signs of soot. If you see soot, its leaking, but you can just blank it off...

Soot wont give a tell tail indication for this.....its down to the valve stiking and the ECU getting in-correct position information.

Take the valve off (two torx bolts) and clean it out well (paint stripper is best).

Also check the wiring loom for damage.
