I've developed a problem with the ABS indicator lamp not going out on my Discovery. When cold it sometimes stays on rather than going out after setting off. Once its warmed up and I stop the engine to go into a shop for instance. then get back in and restart it goes off as it should. At no time do the brakes feel or behave anything but perfect. Is this a common fault such as a semi-choked sensor or any ideas?
