I have a 206 1.4 HDi 2002 model. A light on the dash has come on, it looks like a side view of an engine and is orange. When the light came on there was a single beep with it. The light stays on all the time and beeps once when I start the engine. Could anyone tell me what it is, trhere are no other warning lights on and the car seems to be opeating properly. Cheers Ian
