Ours did something similar when the battery got really low on it. Assumed the messages were down to the low voltage. So maybe check the battery voltage? Sold - Bell a 2015 MY16 Loire Blue Autobiography 4.4 SDV8

one of the main reasons why I have this Hilta 3000 jump pack in the back of my car - only had to use it 3 times in five or six years, but it paid for itself easily many times over |

So it doesn’t give you any warning about low battery first? Just sort of gives up? 2018 P400e AB LWB |

Mine didn’t when it was really low no, it did exactly as you describe and when I checked battery voltage was low, after a charge it was absolutely fine. Worth checking IMO

Get one of THESE, and use it regularly with your new replacement battery, Range Rovers eat batteries like you eat a packet of crisps:

It should give you a warning when your battery is low to "start the engine " doing a lot of shortish runs I always use the ctek every 3-4 months to top it up. It's a 2018 battery as well, so it's soon to be replaced, once I notice its deteriorating. Regarding the low battery alarm, worth checking the DTC's and clearing them get a cheap BT scanner like Autel AP200 2018 SE SDV8 4.4 Byron Blue |

It also depends on weather or not the tech switched battery monitoring on in the CCF during the PDI stage... We often find low coolant alarm, low oil level & pressure are all switched off in the CCF menu! |

Just wanted to report that alls well and the ctek seemed to breathe life back into the old girl. Thanks again for all the helpful advice! 2018 P400e AB LWB |

Still worth getting the device I posted, it will confirm the % SOH of your battery, which I suspect will not last much longer, perhaps surprising you when most inconvenient. “If it ain’t broke, don’t fix it” -where’s the fun in that? |

I definitely will, thanks for the tip. Can I measure the battery from the terminals in the engine bay? 2018 P400e AB LWB |

Yes, no problem with that, no need to go into the boot.

I would add that the best jump-pack of all is a decent, healthy main battery in the car itself.

Should I need then install a new battery, would I need a tool to ‘tell’ the car? 2018 P400e AB LWB |
