I have a vauxhall zafira life 1.6 57 plate, the abs light is currently on, the fault developed whist my partner screeched my car out of the street in the snow very abruptly, wheel spinning hte car in my opinion quite violently, the light styed on for about a week then went off, staying off ranging from a few minutes to days, I hd the breakdiscs and pads checked and front pads changed, the light went off after having the pads changed only yo cme back on in th last few days and stay on again, on the odd occasion whilst breaking at very low speeds the abs has kicked any ideas if this is a mjor problem or a faulty sensor
