If it sounds like you are running over, and dragging a plastic bucket down the road, it's the ABS pump ... It should run for a short time, then stop until you have used the ABS, or it's been long enough for the pressure in the accumulator to fall below the re-pressurise threshold...
It usually does it when there is an audience, it should be coming from beneath the brake reservoirs... (One is the brake system, the other is the ABS circuit, they are completely separate, unless something has gone very wrong)
The pump is literally a bearing that gets hammered against a metal pin
