Mondeo egr valve? - telecaster
Can someone tell me if there is much involved in cleaning a mondeo egr valve , engine in question is liter duratorq TD!

Reason for asking this is at a recent mot the tester really reved the hell outta it , as tho he was really trying to lower the readings....btw was just under the limit.

I can see the valve at the back of the engine and it looks a pita to get at.

Should i leave alone as car is going very well....or investigate further?
