⚡️ Home Charging Issues after Software Update? (Tracking Thread)

[USMA81]

Just a data point: two 2024 Macan 4’s with the latest software installed about 45 days ago. Two ChargePoint level 2 chargers in two different homes in Arizona. Not experiencing any charging errors. I just checked line voltage in home: 122.4 volts at an outlet.

My car was returned today after 6 more days at the dealer. Although they said they were in touch with someone at Porsche, the only thing they accomplished was to satisfy themselves once again that everything works normally at the dealer. Their bottom line is that the only place where charging is not possible is at my home, and regardless of what parameters are in the WSJ0 update, I am the only one at this dealership with this problem and therefore it is my problem. Judging by the lack of response from Porsche when I try to contact them, it appears that the official corporate response is that each dealership should treat it as an isolated problem and a problem for which Porsche is not responsible.

Have them contact Porsche Greenwich, which is aware of multiple Macan EVs with this same problem.

Wow, they actually said that? that Porsche is not responsible for this problem? My mind is blown. Tell them to talk to dealerships in Chicago as well. I suppose this is what happens when Porsche HQ doesn't issue a bulletin notice to all dealerships to inform them of this issue. I feel like, it isn't a small thing, and it is affecting quite a few Macan owners.

So not sure what to make of this, but the past week my car has charged perfectly fine without an issue and voltage has been all over the place. Yesterday started charging at 249 and 248V.

I am a bit surprised that after consistently having an issue for a two week period I have now gotten to the point where it is charging immediately w/o any work arounds to make it happen.

I am going to avoid using departure timers for the near future just to be safe and see if the instant charging continues to work. The one other thing I may try, is to go to a fast charger over the coming few days as the last time my troubles began shortly after a fast charging session. This could mean that it is tied to battery temperature and if that is the case my issues may arise this summer.

Hopefully some of the other investigations being done for others will yield a result as at this point I am just tossing up my hands trying to find a cause and effect. I am going to cancel bringing it into the dealer as the dealer is 45 minutes from our place and they would look to hold the car for day or two.

I read your post and decided to also just try mine. Voltage reading 250 and also WORKED first try... Is it possible Porsche has pushed out an OTA update? People who have been monitoring this thread, any chance we could get some re-attempts and updates?

I thought I read here last week that Porsche was sending an engineering team and test equipment to a problematic EU over voltage location to investigate.

Yes, a team of Porsche engineers from Germany are flying over to my house for proper diagnosis of the issue. They are confirmed for a visiy next Tuesday 8 AM for a full day of diagnosis and hopefully a solution.

Fingers crossed i am sick and tired of having to waste time charging a car at a DC charger which I don't even drive...

Curious those who had the error but now it’s working, looking back was there’s difference in ambient temperatures? We’ve had. Avery warm winter in Colorado but the few times I’ve had issues it has coincided with colder temperatures

I don't think there is any relation between the temps at least in my case. My main home has the charger fitted inside a climate controlled garage so the temp is always the same ~20c (68f).

I have the same charger fitted at my other house, but it is outside. I could charge it with no issues when it was -10c (14f), also, there were voltage issues at this location. At times 1st phase was dipping below 207v even as low as 195v, 3rd phase would spike to over 260v. During these dips/spikes thecharger would stop charging and start charging once the voltage is within acceptable range 207-253v. As far as i can tell, the car does not care about the voltage, it is the charger that stops and not the car. I could increase the voltage tolerance on the charger and was able to charge even at 202v. So, from my understanding the car should or does not care about voltages at least in my case.

I would still try to use departure timers to test if it’s a freak accident that it started charging again. At least you can still use your Level 1 charger to trick it if it starts failing again.

So weird. I thought Porsche didn’t do OTA updates though. So is it possible they actually did that?

Wow! I'm going to go right out and see if my car has healed itself. Not hopeful since I try it nearly every day just to see if something's changed. Inconsistency like this is even worse that consistently bad.

Not a fluke for me, tried charging 3 times and worked first try each time. Ambient temp in the 40's

Perhaps the power line characteristics changed just enough to allow charging (or someone was running a hair dryer or large appliance). Sometimes mine connects within 15 seconds, sometimes it takes 90 and I think my line is on the hairy edge of what is acceptable to the Macan.
