I've not heard this on Vx cars,
But I've had similar noises on other makes - caused by the oil returing to the sump after the engine is stopped (it then needs a few seconds for the pressure to build up when started)
I changed the pattern oil filter to genuine one (and an oil change) on a couple of cars, and had to change oil pressure relief valve on others.
I can't promise this is your problem, but an oil and filter change is a fairly quick and cheap thing to try.
