Or the "deep" reboot part of the update did. So frustrating!
yeah I'm betting on the "deep reboot" that was part of the PCM update campaign…but it's fixed now and car is back online.
That's good to hear. I had so much of this with my early MY21 Taycan – but so far my MY23 Taycan has been rock solid in this (and every other) way. So much so, not sure I ever want to change it!
Same with me on 2020 Turbo, has happened at least three times requiring shop visit of a week or more. Once it was four weeks….
Most likely it was a "deep reboot", though technically could be some software version in your car out of sync with the cloud (cloud updated, your car hasn't for a while) or even some part of the car OTA updated while the other one didn't. Given Porsche software experience I would not be surprised if they only test on recent versions of stuff, never testing all possible mix-and-match firmware versions which could result in customers cars, especially older cars. I worked with a number of car manufacturers on OTA, and some of them are not willing to only update only to a known, tested combination of firmwares - part of it they try to minimize the amount of data transfer required for an OTA, and time to apply it, and chances of successful application. Some also strongly believe the different firmwares are 100% independent, which practically is rarely the case in today's complex systems. Another argument was "if customer applies updates regularly, they are not going to have very mismatched firmwares", which might be true until there is customer who doesn't apply updates for a while, car is parked out of internet reach for a while (or modem hangs), or some ECU update keeps on failing while the rest of the ECUs keep on updating. Tesla does OTA best, and their OTA's approach has been been (almost)all-or-nothing, meaning if you cannot update some part, you don't update any parts. This led to a trick some people used to block Tesla OTA, unplug one of the seat motor controllers - this makes every OTA attempt fail because the motor controller cannot be reached/updated.
New to all of this, the car, Porsche in general, so pardon my question:
I don’t think so!
If app not connecting to car, or no LTE/datacomm, these links may be helpful reading as background:
I know this is an older post. I have the same not LTE connection (2 lines with slash thru them). I pulled the fuse in Row A Slot 11 (LHD 2021 Taycan) and left it out for an hour. Put it back in. No change in the LTE connection or the App.
