A high pitched whine like that indicates a bad bearing. Water pump, power steering pump, accessory belt slipping, alternator bearing, or in the worst case scenerio, Transmission pump.

check the altenator berrings, also check condition of air pump it may be going out,don;t forget the water pump berrings

HIGH PITCH WHINNING NOISE IS FAULTY TRANSMISSION OIL PUMP.HAVE THE TRANSMISSION FLUID PRESSURE CHECK AT A TRANSMISSION SHOP.IF TRANSMISSION OIL PUMP TOO WEAK OR MALFUNCTION.YOUR TRANSMISSION WONT HAVE ENOUGH OIL PRESSURE FOR FORWARD GEAR , REVERSE GEAR, BAND OR SHIFT VALVES IN VALVE BODY.NOTHING WILL WORK TRANSMISSION.OIL PUMP LIKE HYDRALIC PUMP KEEPS EVERY THING WORKING..

This could be anything from the pump in the transmission to the alternator bearings/bushings to the power steering pump. Could be an idler pulley bearing, but I doubt it.
Hint: If the noise is very high-pitched, check the alternator. If it is a lower, medium-high-pitch sound that changes some when you turn the wheels, check the power steering pump. If it is almost like a moan or a "Whooo" sound, that's the transmission pump.

That means the fanbelt on the alternator is not tight enough or needs to be changed, if the belt on powersteering goes via A/C than it might be too tight on the powersteering pulley.

try checking the tension on all the belts(fan/water pump, power steering, alternator). If loose, they'll whine.

need to change a new pump.

does the noise and light occour at the same time ? another cause of a high pitched noise can be slipping drive belts, alternator,powersteering etc so check them for tightness, condition etc, does the noise happen when car staionary and just rev the engine ? if so i would say it is the drive belt/s, go back to the VW dealer re the ABS light and get them to check the OBD as should be done as part of the service , hope this helps
