Hi Scenic 11

The whining sound could be the bearings in your alternator or the water pump or steering pump.

I used to own a 3 series BMW, a whining/humming sound developed, I asked an auto elctrician who said it was the alternator bearing.

Try putting a long screwdriver on the alternator and placing the other end of the screwdriver to your ear, it may help you to discover the source.
Currently in Dirk's garage:
Laguna 1.8 16v Expression, Isuzu Bighorn 3.1td, Yamaha xvs1100 Dragstar, and the usual stuff any one keeps that may 'one day come in handy!'
