it will do an absolute maximum of 330miles no matter where i drive or how i drive
Mine's a Mk6 1.4 and i have the same issue it says it should be 46mpg and i bearly get 36 if i drive economically. Which is about 330 miles ish, it's the same every week no matter how i drive... They seem to quote very highly on their fuel economy to be fair.
your light wont go away without it being taken off
I had my warning light come on after i was messing around with it putting my mates cheap temperature senser thing on it (it made it do 10.8 seconds to 60 rather than my usual 12.8) but it later brought on the warning light
I was stressing because ford wanted £85 just to look at it (i knew what i was wrong, we had done it!) luckily my beloved fiesta turned the light off itself! =) But i'm not putting that chip in it even if it does make it that much faster!!
