@aggie57 can you scan a copy of the work order removing your name and other personal details please? The more info we have the better we can get a picture of what was done and wasn't. Thanks!

Reading your sticky though, looks like my car left the shop on that last visit with the Connect module at 0412, not 0420. Thing is though, it's has been fine since; hope this helps.

Isn’t it totally weird; my car has certainly ‘come right’ since this last visit, and the voltage fluctuations have completely disappeared as well. I literally don’t touch the car for a week and she starts first crank.

I've pointed my Porsche contact to this thread in the hopes it will shed some light onto this issue as it's untenable as it is. Is this patch only for AGM batteries or does it apply across the board to LiFePO4? From there the permutations are endless but there needs to be a solution.

So, what do I do if I take my 992 with RWS to the airport in the winter and park it....on a 5 day trip. Normal car: it will just start. These cars - perhaps not a sure thing. That is just not acceptable.
And while I had a wonderful AG battery, in the winter it had issues so I put an AGM back in and have not had those issues. I miss the cool battery...but the battery needs to work in the cool.

Got a low battery warning 2 days ago and it's been at my dealer for a week... They said the computer board on the Lithium Ion was causing issues... Need a new whole battery, 11k miles, 2020 C2S... Cost is insane.

To clarify - they want you to pay even though they've identified and acknowledged an issue with the battery?

Please find out if you had TSB #2229 and if not if they will install the update. I'm pretty sure this is not a battery issue but a BMS one. But will P own up to it?

should be covered under warranty. Mine was the same situation and I didn't pay a dime. Biggest problem was finding a new one, for which I got lucky.

Batteries are tricky issues as it can be inferred that you caused willfully or by neglect the battery to fail. As mentioned above, supply is one problem, the other just as important is the good will of the dealer/PNA. GL
