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

[rym]

Gidday folks,
Any one know much petrol is left in the tank when the warning light comes on?

The 1.8tfsi has a 55 litre tank.

Thanks!

Not nearly enough.

I'm a firm believer of filling up at 1/4 so I never have to see that fuel light or suck rubbish out of the bottom of the tank.

about 5L, easist way to check is to fill up as soon as the light comes on, subtract however much you can get in from 55L and voila!

(sorry for smartarse comment..)

Thanks Dan, what you say makes perfect sense. But, I've notice the km to empty readings are different each time... So, I thought someone may know the setting of when this is triggered.

7 litres according to my Skoda booklet.

Thanks for that!

The distance to empty is calculated on both the amount of fuel left, AND the average recent consumption. So if you have just been flogging it around town the estimate will be less for a given quantity of fuel left, but significantly more if you have been driving gently on the freeway.

Also don't rely on the distance to empty the computer tells you, it seems to go down much faster than you'd expect over the last few litres in nearly all VAG vehicles (and as previously stated, it isn't good to use the last dregs in the tank).

arnt all tank pickups in the bottom of the tank.So it wouldnt matter if the tank was full or empty,its always sucking from the bottom?

Not nearly enough.

As a follow up on this.

Managed to travel approx 20km on 0km on display last week (not out of want i can tell u)
When i did fianlly find a servo, managed to get 51L in the tank, so there is a fair buffer it would appear...

No, the pickup is attached to the float thingy and moves up & down with the pivot arm. They pull the fuel from about 50-75mm below the top of the fuel level.

I have the sender units out of my current Golf (9 & previous 2 cars (Subaru & Nissan & was surprised at how clean the tanks were. No visible rust, dirt, water or other contaminants.

In the Soob I always ran it to the warning light because there was still 15 litres left.
In the Golf, some idiot previous owner has hooked the low fuel circuitry into the brake warning light on the dash - it drives me insane so I fill up straight away when it comes on - unfortunately that means the tank has an effective capacity of 40L (550km).
