I just got a new battery and alternator and when the car started back up I had a beep sound coming from the dash and Vcs abs and several other lights on. My brakes were also extremely weak.When I unplugged the abs module the beep stopped. The dealer just called and said I needed a new abs module, I have a stuck caliper and about 10 different codes. I asked about zero point calibration but he said he didn't want me to spend $95 for nothing. Are they ripping me off or telling the truth?
