TDi fuel pump whine?

    Have a weird one that I need to investigate, but wanted to see if anyone else has encountered it first -

    Loud (very loud) whining noise when driving, sounds a bit like a wet finger running around the rim of a wine glass. Does not change with engine or wheel speed, starts after about 20 minutes and can continue for the whole journey. Pitch does not change at all, but it does stop completely with the lightest touch on the brake pedal, which makes me think it's the fuel pump under the rear bench (Audi A6 2003 AWX). Before I pull the whole unit out to replace the pump, does this sound like the most likely cause? Cheers.

    I have come across that before in an 08 passat tdi. Changed fuel pump under the back seat. Problem solved
