@lukine you should just get them to downgrade the onboard charger software. I had this and it works flawless now. I'm sure in the future they make have a version that doesn't break charging, but it was just not worth it at this point. the Super Chargers here are 70c a kw/w so charging at home is something that needs to be available all the time. at these charger rates at the electrify canada (up until recently) you would have been better off with a petro car (when you take into account operating costs and capital cost vs opportunity cost of that money in the market).

This downgrade for only the onboard charger was the only thing that 'fixed' the charger issues for me. I had the charger patter alerts you showed until the downgrade (not the whole car, just the charger software).
I have an appointment to bring the car in next Thursday. Not sure if they allow customer to request what to do with the vehicle. But I can mention it to them. Thanks!

You can absolutely do this. I had a problem with the HUD fading out in the sun sometimes. I found the workshop document that detailed this, and, on the second attempt, gave them the specific document number which they then ran through to fix my problem. The first time they simply turned up the brightness of the HUD.

Being specific with document IDs is better than "just rollback the update" is helpful to get them the correct procedure - they're busy, and the notes often don't make it to the shop floor. The document number for the rollback process is ATI #2604, and the PDF for this can be seen here: https://dot.report/bulletins/MC-11032391-0001.pdf

They should. All you have to do is explain to them at that you can't charge at home on AC, post software installs, DC charging still works fine.

If memory Serves me correct this is the service notice:
PRMS Ticket 4031750
Programming Code Level F8G2X Resolves
WSJ0 Campaign 93133540 1.29 ATI 2604

I provided those numbers, and a confirmation the symptoms, and they didn't offer any resistance at all to the programing work;

I would be shocked if your dealer wasn't aware of this and didn't want to do this downgrade. They are hesitant and only want to do it on confirmed cases, because there are other fixes in the software that will be removed. They actually need those fixes, so there will be an update to at some point... but there is no indication of when. Point is you have to be able to charge, so they will downgrade, and then do the new upgrade when its ready.

Final update: i ended up getting an attorney and filed a dispute with Porsche and they eventually bought the car back. I can’t provide more details than that. If i were you all still having this issue, I’d get a lemon law attorney and file a dispute.

So is Porsche sending out this update, or do I have to contact my dealership? And then, is it going to be a crapshoot if my particular dealership will even understand whether this fix that some of you are getting is something that they are capable of doing? So far, Livermore Porsche has not been able to solve my home charging problem. (I am in the boat of it used to work with the new update, and then abruptly stopped a month or two after)…
Well, for those interested, as an update, after taking the Macan in on April 17, we finally got it back yesterday from the dealership! They had initially tried to apply the ATI #2604 roll-back and completely bricked the computer. It was non-operational for weeks! Porsche instructed them to replace the entire computer system and retry the update. After several attempts, it is finally back and can charge at home. What an absolute nightmare.

On the bright side, my loaner was a Macan GTS, which was super fun while I had it 😁

@SeaMonkey80 is the final state you ended up in is a Macan with the 'roll back' for the on-board charger? or is there a newer update to 283.13 that fixes the charger issues without the roll back. I ask, because I'm headed back in for more newer updates than available in 283.13 (story below if anyone wants details). So was wondering if you have updated onboard charger software as part of your last visit.

I dropped off mine this morning, as I am having another new (troubling) problem. I had used the DC charger, outside air temp was only 18c - but after charging, as soon as I stopped, and removed the DC charger (350kw) - the dash LCD went dark, and would not show anything except for warning lights - meaning, if you power cycled the car, no instrument display, but the self-test dash warning lights process still worked. it took about 1.5 hours but the instrument cluster started to work again. I took it the dealer so they could capture the codes. I did in fact take a video of the issue too.

There were no codes stored, other than the 'normal' communications issues they see on the bus they said.

I had to pull over, and grabbed q quick lunch, about 10 min on my drive to the dealer. locked the car, but could see it from where I was sitting. Just before returning the car, the hazards flashed similar (if not exactly like) when the door looks are locking/unlocking (I have prox detection on but was nowhere near close enough). I thought this was part of whatever was going on.

On returning the car, it was function normal again.

The dealer while trying to read codes, did say there was a new software update for the instrument cluster and maybe other ones, but asked I come back when they could work on the car for 2 days (today).

They were not sure if there was an onboard charger update yet but said they would check and update all systems.

@Flying4Fun, this was the roll back that they performed under Bulletin #2604. My Macan 4S had already been updated to 28.13, so there are no newer updates past this one. What the roll back does is bring the High-voltage control box back to software level 0346 (vs software level 0449 under 28.13), while leaving all other components updated correctly. In my case, the dealership screwed up the process and fried the whole system, bricking the car. They had to replace the entire computer, redo the software update, and then roll back that one component to get it back to me so that it can now charge at home.

Your situation sounds horrible, and I hope they can fix it. I asked the techs at my dealership if there were any other updates/recalls available when they returned the car, and they said their system wasn't showing any. Either they didn't apply the 28.13 update correctly to your vehicle the first time, or my dealership was lying about there being new updates available. 🤷🏻‍♂️

@SeaMonkey80 Thank you for the feedback/confirmation. I feel like its possible there is a little from Colum A , and some from Colum B and C - when it comes to what is really going on with the fixability of this/my car.

I will let it play out and hope there is a true fix soon. In Canada, we don't have a lemon law, so options are 'limited'. My confidence in the 'safety' of this software stack is shaken. having systems turn themself off on a car that is drive by wire is concerning to me. I asked the dealership to explain to my how the car protects steering and braking systems - right now when the car goes into park it locks the steering (normal of course) but with everything going on, I am concerned that one day that switch will false positive into 'parked' state and lock the steering when moving. losing power steering is one thing, having its rotation lock is another...

I have filed a safty complaint with the transport safty board for this current cluster issue, provided video etc. Transport Canada has been good in the past with the investigations (and actions) - so if there is a 'fire' where I see this 'smoke' I hope they can use their power to force a solution.

I imagine a vast majority of owners don't have much for problems, and I might be the exception... for a Car that is so enjoyable otherwise.... its equally concerning in these other aspects.

the dash LCD went dark
I've had this happen - only once so far. The HUD continued to work, so the car was drivable. Here's the photo I sent to my service advisor showing the complete lack of dials. The 'Park' text goes away when you put it in Drive. Note the PCM screen still works. This was not after a DC charge, as the EA site was full - I had planned to charge here, so pre-conditioned before this stop.

That is exactly the condition of my screens and systems (I don't have a HUD). The back of the cluster screen was pretty hot, but outside air temp was only 18c - and not even in the sun was in a shadow.

I also used pre-cond before charging. For the entire 30 min charge I was in the car doing emails, and no issues with the display until I got out, removed the DC charger and 10 seconds later was back in the car to a screen in that condition.

The dealer says there is newer software for the cluster than what was included in 28.13 - I will have my car back Tuesday probably (it's a long weekend here and they are also replacing my windshield which requires it to sit for 2 days apparently also).

This was the first occurrence for me also. But interesting to see that others have seen this also.

So many gremlins to chase in this care. I still have the audio system not working, XM radio, FM/AM, Bluetooth etc - but the cars voice command and feedback can still play audio over the speakers... so many gremlins.....

I know this thread is about the charger software, so to keep on topic, they are going to let me know if there is a fix to this also (proper not rolling back one). I'll advise next week if they are able to capture some proof of a updated fix.
