MHEV battery.

ls there any way to check the status of the MHEV battery on the 3.0 diesel?

The last MHEV vehicle l drove (Suzuki) had a little indicator telling you what was going on with it. On the Defender it appears to be invisible. l can't find any way to even check it's working.

Although l assume a warning message will appear if it stops working for any reason.

I had it on my XC90. Interesting but of no real value. Eiger Grey MY23 D250 SE with bits. Known as Noddy.

So when the MHEV battery fails the stop/start no longer works? Bring on battery failure!!

There is actually, sort of a way to look at the battery %, at least if you have a P400 gas motor and a Gap IIDTool.. I found a setting that shoes you the "MHEV battery charge %". I think there's a couple other readings showing "desired MHEV battery charge" and something else.

Oddly my Defender seems to keep mine "charged" around 53% or so. If I floor it or drive uphill rapidly, I watch the % go down. Then it'll go up above 53% if I'm not hooning it around.
