Got a message today with a battery in red and ‘start engine or system will shut down in 3 minutes’ , this happened when I had left the car unlocked with the engine off, and then it was followed by ‘low battery, shutting down’ ?

I have no problems starting on a cold morning and the charge light goes out at start up and start / stop is working properly.

Any ideas gentlemen?

Get a battery conditioner.

Clear your system of unwanted Bluetooth items as hunting drains the battery if not double locked.

Double lock at all times.

If it persists Get fault codes read as faulty locks can drain a battery. FL2 MY10 TD4 GS traded in at 2 years

Thanks Bob. I was actually sat in it for more than 10 hours yesterday, starting it occasionally to keep warm, maybe that has run things down a bit and doing a lot of stopping and starting today, which is when the message came on. 64 plate TD4 SE Santorini Black

All your stop starting is doing is making your car needing a flywheel ring gear and starter motor sooner than later. I turn my off every journey. FL2 MY10 TD4 GS traded in at 2 years

It’s stopped doing it now after a decent run up the M6 and I’ve started to disable stop/ start as per Yorky Bob’s suggestion. 64 plate TD4 SE Santorini Black
