I noticed today when I looked at the CONS readout that it was reading 19L/100KM when I ususally get 11 or 12! Furthermore, I started watching it as I was driving home through stop n go traffic and whenever I was sitting idle the consumption value kept increasing by about .1 or .2 every 2-3 seconds!

When I got home I looked underneath and smelled around thinking fuel leak or something but I dont smell any hint of fuel. So I started it up again, spin around the block. Consumption went from 32L to 2L to 9 or 10L. At the end of my spin around, the CONS meter read about 10L\100KM. I then let it sit idling for about 5 minutes. When I came back it was up to 19L\100KM and was increasing again!

What is going on with this thing?
