Guys. My abs light is on. Iíve completely overhauled the car inc new brakes all round inc pipes etc. One pipe all the way to the ABS unit. Had to replace two ABS sensors too. Iíve not used it on the road since. The MOT is next week, I assume with this light on it will fail. I have removed the cover on the ABS unit under the bonnet, seems to have a permanent feed but no power upon ignition? The relays donít make a sound upon ignition either. VCDS cannot communicate with the ABS controller either. Can I assume the ABS ecu under the rear seat is dead? Any other ideas?
