Why is my MPG so bad??? I cant understand... 70miles ish to £20 worth or diesel... What am i doing wrong???
Things ive replaced are....
Water pump & Belt Kit
I have a tunning box on it, but even without that, it was still around 70miles to £20.
What other problems could it be?? When i boot it i can here like a noise if that makes sense... like a boost leak as such..
But it passed its emissions/smoke test ok.. and i have no EML on...
