My Carista doesn't seem to do anything. I connect it up, have a twiddle,mit appewrs to read the systems and recognise them, but whennIntry to alter any setting it tells me it can't do anything to the van. It's probably me, but it does seem a right POS.
My van had a new battery prior to sale, and I did ask about battery registration as I'd come up against this before in a Peugeot I once owned. They told me not to worry, the van will do its own adaption and within a few hundred miles will adjust charging rates etc accordingly, which to be fair it seems to have done.
