Left Citroen C5 (2005 plate) for 3 weeks. Doors not unlocking with automatic key. No life at all in battery and when trying to turn on no action from engine. No sign that any lights left on. Also brake pedal will not push in at all.
Normally its the boot light. i light stays on in the boot, Brake pedal wont push down anyway on any car??? they have pressure in them, as for key not working possibly battery gone in fob or your key requires programming at citroen dealer

Could be dead battery, I had battery drain on my 04 c5,
if you have sat nav. the sat nav unit could be active all the time this could cause the battery to drain. remove the sat nav cd if you are not going to use the car for more thav a week.
