Sat 29 Mar 2014 08:23. Citroen Xsara Picasso - battery light stays on - elekie&a/c doctor. The black plastic surround just unclips and pulls forward (no screws).The digital display is held to the dash by 2 torx screws.Take these out and this will allow the display to tilt forward.You can then remove the bulb and holder.
Warning light stays on fixed along with an audible alert means that one or more tyres are under-inflated. Check or change the affected tyre. When coming to a stop, avoid sharp steering or harsh braking. Warning lights + service light both illuminate when a fault has been detected with the system. Warning light will flash for around 1 minute basically what the light is measuring is resistance in the bulb filamentnormally one of the lights is dimmer than the other side. one way of checking this is removing the rear light cluster and you should see either a smokey bulb or one that looks like its got a mirror finish, that is the one that needs replacing, same applies to the front
