how far after the Audi A4 fuel light comes on?

[NY]

On my Peugeot 308, the warning comes on when the estimated range (from the trip computer) changes drops below 100 miles. That's plenty of time to find a garage.

On my wife's Honda CR-V, it's at about 30 miles estimated range, which is cutting it a bit fine.

Mind you, I try to fill up before the level gets low enough to trigger the warning, in case the myths are true about starting to suck up grot from the bottom of the tank when the level gets low, and in case I'm a long way from a garage when I start to run low.

It had a pickup pipe that either sucked from about 50 mm from the bottom or 10 mm from the bottom when you moved the lever.

There was a good chance the pipe would get blocked or suck water when you used it.

Cars of the Triumph Herald family only had one pipe but moving the lever on the tank which lived in the side of the boot lowered that pipe down further.

And yes you got to know when the engine stated to misfire as the carburettor bowls emptied, usually got enough warning to get to the side and move the lever rather than come to an absolute halt,though you wouldn?t want to be planning on doing that on todays roads which are a lot busier but also have far less small areas to pull into as lay-bys ,basic cafes and just bits of wasteland have been develop or blocked off.

It's funny how that 'safe' distance can change, depending on where you are, even in the UK. ;-)

Like. We were making our way back from Dunnet Head to Dornoch on her Virago 750 and my BMW R100RT when she indicated that her low fuel light had come on. Now normally / traditionally / typically that has been more than enough warning to finding a petrol station, pretty well any time of the day and day of the week, where we normally motorcycle anyway. ;-)

Long / short, 'she' finally ran out of fuel after probably 25-30 miles and siphoning 50% of what I had left over to her (I had a bigger tank as we would have filled up at the same time) in the hope we would find somewhere before we both ran out! ;-(

Luckily we did ... and that taught us to not take such things for granted, even 'only' in Scotland. ;-)
