Drove the car this morning and no issues.
Went out this evening and pressed the ignition had a couple of error messages, camera fault, fuel low etc and then a very light clicking when I pressed start..
Battery is now flatter than a flat thing (7.8v) and is on charge.
However the rear lights are on as well as the rear number plate - is there any way to turn these off whilst I am charging the car or will they turn off once the battery is charged sufficiently?
Am sure I have read something about this in the past but couldn't find anything by using the search function

Car is a 4.4 TDV8 2011 L322 Autobography - a lot of bells and some of the whistles...owner with no idea!
