Hello and welcome to the forum.
As far as I know the special tools needed are to remove the alternator pulley and not the alternator it's self.If you could leave a link to the tools then I can tell you if you need them or not.
If the car has been stood it is possible that moisture has got into the wiring or the earth connections somewhere,so this is where I'd start to look for your problem.Check the plug on the back of the alternator for any corrosion or greening of terminals,and also check the earths between the battery and the body/engine.
Since the AA have reset the light,has it come back on again?.
I'd rather push my Alfa than drive a BMW....
