Fuel Economy at Idle 2.7l TDV6

I was idling for 15 minutes yesterday and the average fuel consumption stayed on 12.0L/100 and did not move.

EUREKA!!! Perpetual Motion. Throw out the Hiclones.
In my experience based on a few cars, it catches up once the car starts to move again.
If you have been a fair way and it is an average , it may not use enough to go down to the next graduation.
Fuel economy at idle is by definition INFINITE.

Then Again at idle in the instantaneous fuel consumption show 99.9L/100 so I feel it is not particularly accurate.

This is going on litres used and Ks travelled, not from the trip computer.

With the camper on, 14.9l/100k.

Baz,is yours 2.7?

My D2 definitely got better fuel economy than the D4,both around town & on a run

Oh,and at idle:angel:

But it does have more go,is more quieter& comfortable,is bigger & heavier,and will probably depreciate quicker...........

Lol, 99.9 is as close to infinite as the car can show... I'd love if the remaining range dropped to 0 accordingly.

That aside, it must depend on how (and how often) its calculating the average - obviously not based on a time period, more likely some kind of 5 or 10 km rolling average? Or as someone said just overall average since resetting the trip computer.

Yeh Stuart the computer is a little odd

At a stopped idle the instantaneous fuel usage is 99.9L/100km but if you are rolling along at idle the instantaneous fuel usage is 0.0L/100km. Only when the accelerator is depressed will it move off 0.0 when moving.

That aside my average fuel usage around town is 11.8-12L/100km and about 8.5-9 on the highway

It's odd that it shows any consumption /100km when stationary. Previous VAG vehicles I've owned show litres/hour when not moving. That might be a useful readout for on the move as well if it was selectable.
