Hi, it has been suggested that the bulb under the ASR button switch has blown as it does not come on when ignition is on i.e. there are two bulbs and only the faint red one comes on when the sidelights etc. are on. Are these bulbs replaceable or is it a dealer job? Traction Control does work fine, the yellow alarm button works fine on the dashboard tach; in fact I'd have been b****red without it last night !
