2026 Software Update via Dealer - What does it do exactly?

[Tblue87]

It is very clear WSJ0 = VR28.13
What @craz8 above says is true.
Update is exactly the same as released 7 months ago.
Zero 2026 features made it to 2024/2025 models.

Is this the update that is causing the home ac level 2 charging issues?

It's not like there are several updates.
VR28.13 is the last update.
VR28.11 is the previous update that was installed during PDI for my Macan as I am sure for most as well.
If you have no issues and want to play it 100% safe you may delay the update to VR28.13.
While the update is the same, as dealers do more & more updates on guinea pigs/lab rats/ customers cars they are less likely to fry a module or 2 (happened to me on a different update).

Just to add perhaps more confirmation, when I dropped of the 4S this AM to get caught up on service campaigns, the order included WSJ0 , update to version 28.13.

If you read through WSJ0 posted elsewhere here you will find install instruction revisions corresponding to pauses. Better instructions that may reduce the number of bricked modules (AKA computers). Its always been the same big software package (lots of different computers)

I would not be surprised if the PCM UI changes that bring MY2026 changes get delivered OTA. It seems the various ECU and control unit updates need to be dealer updates, but they’d probably be a dependency for the UI updates. Anyway who knows, we’ll see what happens.

My opinion is that this is what is going on. Update the core systems to 28.13, followed by a set of OTA PCM application updates to the latest UI. Info such as battery State of Health is likely not available to the UI without the 28.13 update.

I don't know how the dashboard UI is handled in Android Automotive, but all the PCM top level buttons are individual applications that can be updated OTA. The Porsche internal ones are handled slightly differently to the third-party apps, as they don't appear in the App Store, but the process to update is the same.

I've worked in hardware/software/subsystem integration for vehicles for decades. Companies do not typically have the capital to get something like a car or truck to market in time so partners and vendors are assembled to get it done. Each is different and have different software maintenance.

You would think that in an ideal project, everything is developed in house. But then then there can be issues and there is quite a bit of risk. Rivian would be dead now if it wasn't for all that Chinese capital backing them up. Tesla uses their customers for betta testers, an approach that saves money, but makes for a unpredictable and inherently flawed product.

Porsche doesn't seem to be doing anything different than large conservative companies. I'm seeing some naivety posted here for software/firmware maintenance for these kinds of integrated platforms. The subsystems may continue to evolve and improve and easiy updates. But WSJ0 appears to be a big network architecture change cut across a dozen subsystems that have to play well together.

Anyway it is not as easy as the armchair quarterbacks here seem to imply, they just don't know what they don't know.

And it does seem that 28.13 had to happen before improvements to smaller apps or subsystem can happen which very well could be OTA.

I like your optimism. OTA Updates

I stand my point from the first page, I would be very much surprised if we ever get any significant update, especially for MY24 and MY25.

my prediction no "meaningful" OTA updates (anything beyond PCM) for current generation Macan EV's - maybe with a 2028 .2 refresh - but even that I give low odds to - the next full generation of Macan EV (if there is one) will have greater OTA capabilities…

my $0.02 worth…

Makes sense, thanks

and people wonder why Porsche doesn't have OTA updates…I'm reading the first few pages of the updates instructions posted on this thread…

• you need the vehicle on a 90 amp 12V charger during the update process (1 kW power supply - seems about right to run all the on board electronics during update)
• can't and do not sit in the vehicle while it's happening
• "Destruction of control units" <----- my personal favorite line from the whole tech bulletin
• don't mess with the ignition while it's happening…
• don't do it more than once unless it fails…

I remember these sorts of update instructions for stuff I was playing with in the 1970's…

Yikes. Yes - that doesnt sound good. Interesting spot. I bet there is more good stuff. kind of like digging into the epstein files. ooof. Not pretty.

I've seen this often in highly regarded name brand products though 2010, the last I looked, mostly in the subcontracted garage developed boxes that either forget about all the things that can go wrong, or didn't care, lose a bit at a bad time it probably bricks a CPU. But we learned plenty of hard lessons in the 70s and 80s..

Second Macan is in for windshield replacement today and will also get the software update. First Macan went in for software 2 weeks ago. No issues in two weeks on first vehicle. Dealer is likely one of the largest in the world, and is very competent.

On a section of road that recently was torn up and rerouted, I was getting Innodrive errors on the new section (likely due to a gps mapping database discrepancy). That went away, I think, before the software update. If I recall this correctly, then that would seem to imply minor OTA updates to roadway data. Perhaps we all can hope minor, frequently changing data could be updated OTA (roadway data, charging locations).
