Hello all.
So, it's a 2014, 40k on it, 3k by me. I was getting 9 or so litres per 100 km (I haven't figured out how to display in MPG.) All of a sudden, this...
I started getting awful mileage, like 12, 14 L/100k. This badness occurs while idling. If I reset, it automatically shoots to 50 L/100km. As I begin to drive, it will come down, but while stopped in traffic, drive through, etc., it rises quickly..12.1, 12.3, 12.4, and doesn't stop until I drive again. I have yet to manually calculate my mileage, (started with a full tank today), but it doesn't seem good.

I hope someone can help.
