Hi all. 2010 l322 range rover tdv8 3.6 with 95000 miles. Last couple of days, a few miles in "ping" charging fault message + red battery symbol +red triangle. A few minutes later, warning lights disappear. Another few minutes "pings" again, same messages/lights. Couple minutes more warnings disappear and don't return for rest of journey. Same today. About 5 miles in "ping". I timed it this time. Warnings stayed on 9 minutes then cleared. 1 minute later, they are back. 3 minutes after that they've cleared again and stay clear for next 40 miles, A road and motorway cruising at 70mph.
Battery showing 12.4v with engine off. Just over 14v with engine idling at about 800rpm.No appreciable increase in voltage with higher revs.
I appreciate many comments suggesting demise of alternator at this age/mileage, but the way the fault presents, early on, then disappears has me scratching my head. Any thoughts?

How old is the battery?
Does it charge from a mains charger and hold it?

Have the battery tested. 12.4v is a little low and these machines rely heavily on a good battery.
As said a possible faulty alternator also as this will take the battery down with it

Never had any starting problems and sits for days in between using. Just bought a ctek battery conditioner which is now connected at all times on driveway

Bosch battery on when I bought it 18 months ago. I've neve had to put it on charge and it fires up every time, even after sitting for days. Just had a quick look underneath. Can even see an earth strap and barely see front of alternator, let alone aknnections at rear. A while ago I began suffering from claustrophobic vertigo, which makes me feel ill lying under car. Very frustrating and hs curbed any mechanic ing which requires that position!
Local lady specialist thinks alternator is most likely cause, but I am going to affix additional engine earth strap somewhere up top and see if fault goes away. Don't you live intermittent faults!!
