K3ogh_sti

Just got my 2005 sti back on the road after 2 years as it needed a underside refresh, new callipers suspension etc, my abs light is coming on at a certain speed then going off when I restart the car and coming back on at speed, when the light is on and I'm turning at low speeds I'm getting a clunking noise from in and around the front wheels, any ideas what the clunking noise could be? Doesn't do it when the light is off? could this just be down to the car has been sat for a while?

Really frustrating as I've just put a lot of money into sorting the underside out ffs

Cheers
