Last night I was out playing taxi for my eldest daughter. The red "battery/alternator" red screen and audible alarm sounds three times.
The onboard diagnostic shows 10.5 volts at idle and about 13.5v when moving. When I got home I put the Ctek on and only the first thre lights went on. Left it overnight, all lights on and started healthily.
Later in the day it also started healthily. But I've just been out, it started, but not too vigourously, I only drove half a mile to the garage (it's very cold) to get some things...when I came out it only just started. When I got home, engine off and when I tried to start it...dead.
So...battery or alternator? The Ctek is on again...two lights again.
