Got a message this morning I’m not sure about. It said low cranking voltage 8V.
See pic.
However the van starts on and the leisure battery is still at 12.8v

Dont worry too much about the bit in tests as they are more specific to a standard alternator system and not so much the stop/start system in the T6.



out of interest whats your daily readouts look like now things have settled down?

Here's my starter and Aux readout for a day slot.

Nothing to worry about, voltage can dip to around 9v on first start on a cold day due to the strain on the starter.

You can disable those alerts in the settings menu..

Thanks, strange thing is it happened at 8am On Saturday morning. Not exactly a cold day. I started the van to see, it started immediately not like the battery was low. I got the same message at 8am on Sunday but not this morning. Both messages were when I was parked at CamperJam.
