L405 SOS limited function

TT7173 · May 10, 2023

Hi all, hope someone could help me please.

I have a 2017 Vouge which I didn’t start for 6 weeks, after fully charging the battery I’m getting a warning on my dash “SOS limited function only”

I believe this is to do with the secondary battery, does anyone know where the secondary battery located? I checked the right side of the boot and couldn’t find one.

Thanks a million!

Is there a warning label on/near the main battery? That might give a clue

Is that the label that says "If disconnecting this battery do not forget to also disconnect the secondary battery located in....."?

Or maybe there isn't one?
Have you checked on the manual for the car?
It could also be that your main battery is duff after so many weeks

You need to go into the boot.... pull the panel off the right hand side wall (only secured by several plugs - so pulls off easily)... behind there is a large number of fuses and the secondary battery......I had to take it to a specialist to replace the battery and then they had to reprogramme it ..... problem solved..... When they ran the diagnostic and sent oft to JLR they knew immediately what it was....mine is a 2017 vogue autobiography...
