Hey John, and anyone else around.
I just left mine plugged in for a couple of days so that it could do any balancing that it fancied, came back to it and found a totally unbalanced battery showing horrible stats!
299 GID's, SOH=82.20%, Hx=58.98%. 62,800kms (39022miles), 39 QC, 1787 l2.
So I've had it 6 months, done 8000kms (5000miles) and seem to have lost 3% battery health (although the figures do jump about somewhat).
If that were to continue then I could do another 43,000kms (27,000miles) before arriving at 66% which I think is about when the fourth bar might go to paradise. This would take me to 105,808kms (66,000miles) still well inside warranty. On the timeframe mesure, it looks like 32.25 months or 2 years 8.25 months which would take me to about the middle of May 2023... and the warranty expires end of December 2023. So that is quite tight.
Specifically I believe the battery health has to remain below 66.25% for a full month before the fourth bar will go, and given how the measurements vary I think it could be touch and go, especially if degradation slows though the winter months.
Oh, and just my two cents worth; please don't reward VW for being the biggest fattest liars in the world, on an issue that actually concerns us all directly, by buying an electric car from them. They clearly don't care about saving the world, so they should be the first to suffer the consequences!!
I am stunned on a daily basis how many brand new VWs I see driving about here (France), its not like they're any better than any other of mundane brand offerings of the moment, but nobody cares, not a jot. The caché associated with owning a VW doesn't seem to have been affected in the slightest, unbelievable. And their perceived market is upmarket educated yuppies with children or indeed grandchildren... the kind of people who are supposed to think before they act, not try to go one up on the family chevy next door. Its a sad world.
See you next month, if we're still here.
