What is the make and spec of the battery? a cheap undersized battery could well be US after only 2 years and there's plenty to suggest it is the battery.
As others have said put a new battery on, it's easy and relatively cheap - For the extra cost I would fit an AGM even though it doesn't "need" it. No doubt others will disagree but I found putting an AGM battery on a 07 TDV8 solved all manner of seemingly random electrical niggles.

Don't believe it, stuck an agm on mine (2007 sc) lasted 6 years, none of telling it it had a new battery or anything, just swapping out lead for agm....

2006 on L322's were fitted with Lead/Calcium batteries which have charge requirements very similar to AGM & Enhanced Flooded types so it's perfectly acceptable to use them in place of a Pb/Ca battery.

Happy to be corrected on this  2012 TDV8 Vogue (L322)

It’s the charging systems which are smart, Lead Acid batteries are all dumb generally, i.e do not have an onboard BMS. “If it ain’t broke, don’t fix it” -where’s the fun in that?

Just to update this thread and not leave it open ended... I got the battery tested properly and it was shot, a new battery seems to have done the trick!
