Ignition system sounds probable on vhicle when everything gets warmed up. High pitched hum could be bad tire or worse bearing.

Testimonial: "Thank You for your response. The huming sound is present on idle from start-up,tires have just been replaced, would fuel pump be suspect?"

Hi. This is more of a fuel filter issue than a pump issue although, a bad fuel filter will eventually destroy a fuel pump. When the filter is restricted or clogged, this will tend to work the pump harder than normal. this will over heat the pump, therefore, shortening its life span. I recommend replacing the fuel pump and filter and, adding a fuel additive like techtron fuel injector cleaner/water remover as well.
Please rate and have a great day:)

I would start with a fuel line psi test. then have your fuel acumulator.
check this out and see if it helps. It sounds like you are priming the psi up when cranking then it can go. but when you let it sit the pressure drops and has to build up again. I a not a VW person myself but love tinkering, so let me know how it goes.
