Hi. I have a 54 plate focus tdci. Been getting poor mpg (around 42) for some time. Having done some searching on here its possible my inlet manifold/egr is clogged. Unlike the Mondeo on the focus these are a complete unit and cant be seperated so cleaning may be quite awkward. Has anyone done this on a focus tdci and if so any pointers as to equipment needed or techniques to make the job easier will be greatly appreciated.
