My Citroen Xsara 2001 is beeping every 30-60 mins or so for an unknown reason, 5-9 short beeps every time... Anyone knows what could trigger it? And there's an orange kinda flashing dashboard light above the fuel meter which I don't have a clue what it means... It's on most of the time, dimming and turning off regularly. If anyone's got a clue what those beeps / light means please reply, thanks.
