I recently received a notification about a software update for improving battery diagnostics that will take seven minutes install? Does anyone know exactly what this update includes? I saw a number of postings about other software updates that had negative impacts on charging. If this is the same update, I would prefer to skip it.

Thanks,

Anecdotal sample size of one, but I found that after installing the update my vehicle was cured of the "disconnects from the app after a day" syndrome. It has consistently remained in contact with the Porsche mothership, and hence my app, since the update. Beforehand it would consistently stop talking to the app service if not driven/communicated with for a day or so.

Thanks,
A couple of weeks after installing it, I got "Electrical System Error ..park.....". Made the car unusable. Took to dealer and waited 3 weeks expecting a new/rebuilt battery. Instead got an update (to the update?) that was applied and "fixed" the problem (for now anyway).

It's hard not to do these updates because you never know ....
