2025 Macan 4S EV - "Assistance Systems Limited" message

One of the three times this happened to me it did not clear overnight, but did spontaneously clear after about a half an hour of driving in clear weather, so my only suggestion short of going to the dealer is drive a bit first if you haven't already.

I've got about 60 miles on it...no change still. Hopefully it will clear sometime pre/during the road trip.

That's already more than I drove before mine cleared.

Tried all that on day 1 with no change unfortunately. Looks like a dealer visit is in my future.

I tried all of the soft resets and cleaning to no avail. The only thing that woked for me was to eliminate my profile, reboot and then activate everything again. No problems now for 2 months.

Does that entail anything more than entering your login and password? Does it mess up Electrify or Porsche subscriptions? Thanks!

i just had to enter my login and password. The EA and Porsche subscriptions are part of your account and they repopulated. If you have installed apps ( eg, Tidal) to the PCM they will have to be installed again along with account information. Hope it works as easily for you as it did for me. Mine crashed on the drive home from purchase and I just decided to delete the my profile in the car and start again.
