Had a config issue with solar panels and leisure batteries which I believe has confused the control panel (negative from solar panels was wired to rear leisure battery negative, not chassis earth).
Have located and fixed this, but control panel now thinks leisure batteries are flat (I am guessing as a result) and says “Battery flat. Charge now!”, and won’t let us access other panel functions to operate fridge, roof etc.
Trouble is that:
1. They’re not - they’re full
2. Running engine and putting on hookup doesn’t budge the warning (presumably because no charging is actually happening, because batteries are full)
3. Ignition on/off, driving it etc doesn’t help
We are on holiday so my idea is to leave it overnight with no load or charge on batteries, to see if the computer picks up that it has two perfectly fine batteries and recalibrate
But if it doesn’t, all I can think of is a hard reset. I am presuming disconnecting main van battery positive will do it, but is there an easier way? I have tried pulling fuses 5-8 and another fuse that @Loz kindly suggested, but no joy.
Any suggestions hugely welcomed, it is kinda spoiling our fun, and we have already had it in with VW who held it for two days, did a “software update”, but no joy (it worked when we got it back from them, but same think - I do think the root cause was the solar, now fixed).
