Yesterday the fuel reserve alarm came on.
Autonomy was 100 km more or less.
I have done 705 km and the average was about 15km/liter.
I have calculated to have other 5 liters in the tank.

After other 20km I filled it up.
From the reserve alarm I ran another liter, at least.
I could expect to have 3 or 4 liters in the tank.

I have filled the tank up with 47 liters!
...but the declared capacity is 48 liters...
So, three possibilities:
1) the tank is bigger, 50 liters...at least
2) the reserve alarm is not reliable
3) the liters I have payed are smaller than nominal....

So, how big is the F54 fuel tank? And the reserve alarm...is reliable? How big is the left autonomy...100km?

Had the amber warning come up on my F54 for the first time the other day as well on my way to the petrol station. Said i had 37 miles left and I was going less than 2 miles to fill up. Put in just under 48 litres which did surprise me as well.

What is the true size of the tank in the car ?

I got to say is 60 litres tank as I was trying to fill it up all the way to the cap but I couldn't fill it up all the way to the tank as I was there for a very long time at the petrol pump. I end up filling up 56 litres with one bar left on the fuel gauge before I arrived at the petrol station.

Haha you'll be fine.

FYI: I did 18 miles on "---", albeit I ran out... But you can do up to 18 miles in an Auto SD on "---".
