Hello vdub buddy :wink: the abs system is a very exspensive thing when it goes wrong, as I just found out.
First, just to let you know, get the abs codes read and that's a start, then this will tell you if there is a fault, sensor, wiring, or even the pump! this can be done at most big garages, but make sure you see them do it, as they might say it's something when it's not, as some garages (as we all know well) :lipsrsealed: can con us into spending money when it's nothing at all.
I have a fault with my abs, and found out on the readings (done at AMD in Bicester) it's the main pump, and thats exspensive £370 recon, and even when that's done, there might be a sensor gone, but if yours is a sensor on one of the wheels, exspect to pay £65 -£80 for one.
I've had to resort to leaving mine, for now and live with no abs, which isn't a problemr to me.
just disconnect it, and take the warning bulb out.
let me know how you get on, hope this has helped.
oh, has anyone got a working, ABS pump

going cheap?
