when sat idling I watch the mpg on the dash slowly drop. It goes from whatever it was whilst driving e.g 47.5 and i've seen it drop as low as 20 mpg untill i pull of again and then it goes back up. It doesn't do it all the time but is fairly regular. I've had a quick search but cant find anything, can anybody enlighten me?!
cheers

It's normal. If you're sat still you're using fuel and getting no miles from what you're using so it will drop.

Its only just started doing this though, and I have owned the car for 5 years. Surely it would have done it from day 1 and happen every time I stop?!

There are two different MPG displays on the trip computer, one tells you your total MPG and the other tells you your current MPG. Are you sure you're not looking at the wrong one? Perhaps you pushed the button on the stalk by mistake and are now looking at the live one when you were always looking at the total one before?

Well on my trip computer the first MPG reading doesn't move at all barely and is always sitting around 56-60MPG, the other one doesn't come on unless you are doing over 20MPH and it changes every second depending on your speed. If you go under 20 MPH it just shows --.-MPH until you speed up, it wouldn't show a figure when sitting idle.
