Ive had my 2010 L320 RRS now for 6 months or so, previously Discovery so used to similar issues I might get with the RRS, I love it, it’s great! It complains now and then with suspension errors and the heating does not work anymore, I have an iCarsoft from my discovery days so I can use that.

The thing is after a longish journey a “gearbox” error showed up and then on restarting disappeared. After reading many many threads and forums I stumbled across a “poor battery” could cause many issues that I was having. After testing the battery it needs replacing and only holds just 11v. I went to find out what battery it needed and I was offered a start stop at £270 and a normal at £150, thats quite a difference considering it doesn't even have start stop. The battery that is in is start stop, but why?

Anyway I purchased the normal 019 battery which I am hoping will solve all my gremlins, including the climate control.

I can only hope I guess

Seems to me that whoever is calling batteries stop/start really means they are AGM batteries 2015 L494 SDV6 3.0 HSE Loire Blue
2006 L320 4.2 Supercharged
2009 BMW X5 M-Sport - Gone
2007 L320 2.7TDV6 SE Buckingham Blue - Gone
2011 Jaguar XFS 3.0V6 Diesel - Gone
2009 (59) L320 Facelift 3.0TDV6 HSE White Wrap - Gone
2008 BMW X5 M-Sport - Gone
2005 Audi A6 3.2V6 Quattro S-Line - Gone

As the car is 14 years old very unlikely it still has the original battery fitted and someone replaced it with a AGM type battery, as I think you may find L/R started fitting AGM type from the factory around 2011/12 on the diesel vehicles not petrol version though. Although I did fit a Varta AGM battery to mine which is also described as stop/start, although it was not necessarily a requirement for a AGM it has lasted 8 years so far.

Worth checking the alternator is ok, too.  2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed
