ABS light

Hi chaps my abs light has just come on. is this a common fault? what to look for first? also sometime she runs a bit limpy on tick over and when you rev the car it revs nice and smooth but as soon as the revs drop from 2000rpm to about 900rpm it is lumpy any ideas? it is a 1997 bmw 2.5 diesel

common one faulty alternator causes many abs lights to illuminate.

What type of R/R have you got ?
