I have a new-to-me Sedici, 07 plate, 1.9 Multijet, Eleganza.
I seem unable to change over the units of fuel consumption from l/100km.
The owner handbook guide on how to do it just doesn't work.
I could convert it over in my head, but would be easier to see it in MPG.

Grateful for any advice!

i never got round to sorting my customers one either.

But try the advice in this thread:
