Help! I drove the van to work today, Vauxhall Movano/ Renault Master. By lunchtime I noticed I left the headlamps running which had flattened the battery. Following several attempts to jump start from another vehicle, I felt there was enough of a charge to start but that there was an issue with the immobiliser. I decided to plug into an external battery charger. By the time I was leaving work I disconnected the charger and attempted to start. By this stage the charger was telling me it had a 60% charge. Again the same thing. It felt like there was plenty of cranking amps but that the vehicle was immobilised.
I have got a lift home now and will leave the charger plugged in for a few more hours. I hope to be able to go back to check on it then. Could there be an issue with immobiliser electronics needing a reset after a flat battery?
