The warning came on about two years ago when the old battery was failing. Last Thursday in the queue to check in to a ferry there was a lot of long waits where I turned the engine off and then restarted and it came on, and has stayed on even after four days and about 550 miles of driving. The Ctec battery monitor is generally amber, was green after a few hours on a borrowed 4 amp battery charger but turned amber again very quickly. No voltmeter here to check voltage so I think its down to a weak battery. Has anyone had the same issue, and was it the battery or a real problem with the pedestrian system? I am now in deepest France and not back until 22nd. The car still starts first time.
