Mine is back again (2nd visit) they are now replacing the assistance systems control unit.... and I assume aligning software versions again. Hopefully this corrects the issue for me. It seems that many people have had good luck and no faults.

I have (currently) about 10 ignitions cycles of issues, then it its perfect for approx. another 10. I recorded video and the service department was actually impressed with the number of times it didn't work; and the different failure states. Always different, despite the same fault codes. At one time, I was able to capture about 16 different failures in the PCM.

I was original told that these were false positives, which I was able to prove to them that they were 100% not false positives because the systems reporting errors actually went offline too, such as blind spot and for me the most problematic was the headlight control system - living in the country in dark northern winter lighting - I need the headlights to work in high beam mode (only low beam would work in failure mode).

I'm hoping that the hardware has in fact gone bad, and this replacement combined with the software everyone else had such good luck with corrects this. Should have my car back in a few days, and maybe another week or two before I have any idea if the problem is sorted. but probably a month to feel confident in the repair.

I received the car last Tuesday after the update. The same problems persist......
Still the assistance systems control warning appears and music muting randomly.
I will call the on Monday to see what they will tell.

100% agree with Joev comments on Innodrive.

Although I’d add that for me it is very useful in stop and go traffic. Keeps me from rear ending the car in front.

I do use the active cruise control for stop and go. I just turn off the lane keeping so I'm not constantly fighting the steering.

Has anyone managed to get a comprehensive list of what’s changed and where from their OPC?

I saw a post where someone had detailed some of the high level changes and used an LLM/GPT to summarise the changes.

I also saw some Porsche update docs that referenced a FAQ with a link, but it requires a login to access. When I asked my OPC they said it was an internal document only and couldn’t share it.

I’m particularly interested in the below from the update narrative:

What is the issue?​

A series of updates to various control units are available for your vehicle, which brings the look, feel, and software of your Model Year 2024 or 2025 vehicle in line with current 2026 models.​

The reason I ask is that my car was in the dealer for 5 days and they had significant issues getting the update to complete. Various posts from other owners post-update appear to show different UI/UX and even menu options to what I’m seeing on my car.
I’m trying to work out whether the 5 days of failed updates at the OPC mean I’ve not actually had the update applied successfully — or at least not fully.

The only UI change I've noticed is this one in the Charging app - the buttons to open/close the charge ports (likely not visible for manual charge port cars). Any other big UI changes you might see online are for the 2026 cars that do have a different UI implementation.

Also, the Android Automotive Kernel version is updated with the new software. The new version is this, and is more definitive than looking for minor UI changes.

That's interesting... I had same update done on Nov 20th, I wonder if the version they were doing on Nov is the same as the one they are doing now? Because there is no way I would have been able to get the Android Auto Dec 5 update back on Nov 20th.... My car has been away all week getting a new Assist control module installed/programed, hopefully they do the whole software update over again to bring to current version. I am hoping to get it back in a few more days and will check this version against what's int he car. Wondering how many of my issues will remain after this current attempt.

That's December 5, 2024, a whole year earlier. Porsche software updates are not to be rushed.

Ok... I missed that date (2024), brain was calculating 2025- 1 year....

The Monday, March 10, 2025 build date is the key one for VR28-13.

Note that if you have WSJ0 update to VR28-13, there is no different possible version you may have based on when you got the software. Any different update would have a different code number and would not be WSJ0/VR28-13

I made a thread/table here with the only concrete evidence we have for now:

Important to note that VR28.13 (or KD2) is not the same software as MY26.
