Your long battle with the abs light may have been resolved within 30 mins - 1 hr of actual physical work on your end. If a glowing ABS light frustrates you to the point where you've made the decision to never own another MB again, I'd hate to see you having a rough idle/hard start issue . If it turns out one of your sensors is toast, I may have an extra that I could send you (front sensor only).
