How many litres left in the tank when warning lights come on?

[Treza360]

I had my light turn on the Gateway near Boondall a few months back. Drove another 71kms across the gateway bridge through to the southside suburbs to fill up at my local servo in peak hour stop start traffic (those who have seen the roadworks and made the drive southbound in peak hour will no how bad this is) and managed to not have to run out of fuel.
It was a highly stressful journey. I put 61 litres into the .:R that evening. I have a 62L tank.
I figure that doesn't take into account any fuel that is currently in the fuel lines.
Suffice to say I think you can get a fair few kms out of the VAG cars before they run out of fuel (especially since my fuel economy isn't the greatest).

My light came on today as soon as the needle hit the red zone. I probably drove it another 15km. When I filled up it took 48L. Allow about a litre to drive the 15km, so I guess the light comes on with 8L remaining.

Yesterday I put 51 litres into my RS, and had only driven about 10 (hard) Kms after the light came on. It seemed to go out and then come back on every time I floored it (still running in).

SWMBO commented that the wagon seemed to be telling me not to waste so much fuel when we were nearly empty

My U13 Bluebird used to do that. The fuel light was controlled by a thermistor (???) an electronic gizmo with a current going through it. The fuel covered the thermistor & cooled it which kept the circuit open. When th efuel got low, the gizmo would get hot & close the circuit. If you drove with vigour then the fuel would slosh over the gizmo & the light would go on & off. If it continuously stayed on no matter what the driving style then you knew it was really low.

Golf 3's had a 55L tank with 7L in reserve
Passat B5's had a 62L tank with 9L in reserve

Considering that VW probably figured out the best compromise for this a very long time ago I'm guessing its still 7L for the MKV, all this was obtained from the owner's manual.
