Whine/moan noise when stopping/stopped

Hi Guys

I have an issue with the S3, when slowing down, stopping i am getting a fairly loud whine/moan from the drivers side in the engine bay ,AKS had the car lately and were going to check the alternator clutch pulley , Alex has just told me all looked ok, the noise had gone but its back and even louder this afternoon , my battery is only 30% and i am going to change it , I have read that a weak battery can put extra load on the alternator .

Anyone experienced this and found a cure ?

If you turn off the engine and coast to a stop does it do it?
Also does the type of road surface make a difference?
Have you had the geometry realigned recently?
