One problem ive noticed is, the onboard computer doesnt really give you an indication of your mpg, it gives you "the current journeys mpg which is fine but doesnt give you the average for the fuel that youve burnt on other trips from the same tankfull. Ive had new peugeots prior to "seeing the light" with VW, and the trip computer gives you choice of , current , average, and doesnt reset to zero everytime you turn off the ignition in the gti!. i kinda think our gtis are burning more then we think....
