My ABS seems to have developed a baffling fault - when I turn the ignition on the two lights follow the correct sequence and the 'anti lock' light goes off but when I start up the 'anti lock' comes on and stays on. Any ideas what this is about?

Fortunately this only arose 3 days after the MoT - if it had been 3 days before I would have been well cheesed off!

Could be a 'sensor not detected' type of fault where everything is ok until you start rolling. Then the ABS unit gets signal from 3 of the 4 wheel sensors and complains. Check out the ABS codes link from Tom Townsend

That's what my initial thought was but the 'fault' is detected as soon as the engine starts and the car is still stationary, not when motion is detected (or not) from each of the wheel sensors.
