Re: Agh! ABS, BAS and ESP Light On and Spoiler Won't Go Down!
Was going to buy a battery, but my son (who's an engineer suggested we check voltage) Checked battery - got 12.5V with car off (not started for 24 hours), 12.5 with ignition on and 14.5 with car running. Also compared the "car off" readings to a new battery, they were the same. We're now going to check the wheel sensor connections.
