Yep! Our previous MK1 could usually get down to empty on the gauge fine with no adverse effects (my mother has a tendency to keep driving and not even look at the gauge until I fill it up), but one day with the needle above the empty mark and low fuel light not illuminated, it died on the driveway and wouldn't restart. Turns out it had ran out of fuel, despite the gauge still showing a positive reading.
That said, for your situation I'm dubious as £47 would not fill it to the brim from empty, as it is a 55 litre tank (at least on the MK1s anyway) which would cost around £66 to fill, depending on the price. £47 would only get you around 40 litres, so even if you put 5 litres in from a jerry can that still leaves 10 litres unaccounted for.
