I would say that if the fault would be covered by the warranty (assuming you were past your one month not being able to claim which seems very odd to me) then its something that the dealership should/would consider correcting. Although having said that a noisy fuel pump if operating correctly might not be covered.
My car which is an '05 has alot of squeaks and rattles certainly more than the '02 focus I had before, I dont blame VW I blame the shoddy british roads, we all pay enough motoring related tax for them to keep the roads in good condition!
