Reading this article online and one part which says running low on your tank can damage the fuel filter and fuel pump.
Maybe years ago when cars had metal fuel tanks there could be debris in there but now most/all cars have plastic fuel tanks so very little chance of there being debris in there. Even if there was the fuel filter would catch it, that’s it’s purpose and it certainly wouldn’t damage the filter unless there was an unprecedented amount of debris in the bottom of the tank. It shouldn’t damage the fuel pump, poor reporting or scare mongering or maybe just a slow day at the press?

I often let mine run down to 5m on the range then fill up. I'm always getting told by the other half that it will damage the car! Not personally seen any problems doing that on any car that I've owned.

Not sure about tanks having lots of debris in the bottom - the fuel filter would deal with this anyway. There is a possible issue with running HPFPs on diesels as these are self-lubricated by the diesel fuel itself - for the same reason people get worried about changing the fuel filter and not first priming the system via VCDS. Also my understanding is that a lot of modern diesels with DPFs won't do an "activated regen" when the tank fuel level is below 25%, so running around urban areas with a perpetually low fuel tank could cause DPF issues.
 
Having a low tank gives more surface area for condensation hence water in your fuel

Never had one. Only owned an A4 1.8t for 6-8mo. Thinking of lookin for another.
