There may be a nuance here. It is rare that manufactures continue updating older module software after a hardware change as most of the time the new features require the updated hardware. Neither BMW nor Tesla does that unless it is a safety recall. Just about all manufactures update software...

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.

If the GTS is a 2026 model, and your 4S is a 2025, the hardware is a bit different and Porsche has no plans to port it to older hardware.

I've read of a few here. It is common for one module to fail update the first time but it usually takes on the second try. Sounds like yours is not taking on the second or third try. From what I've read here, once they figure it out there are no further problems with the car. There are a...

I use the built in Nav when I use the Porsche ROADS app integration for suggested routes, scenic or otherwise. In my area there are several shared driver generated routes that are interesting for a Sunday drive. Anyway I found it easy to use and I notice it is way better at indicating the...

As stated here and in other manufactures forums, there are Tesla owners (fanboys) that don't know what they don't know that think the world of Tesla software, but others that understand it is dangerous crap covered with marketing BS. Their support forums are full of issues. Technocrat owners...

I'm just satisfying my curiosity at this point, but another data point, if there is any interest. Line voltage had been varying, mostly between 246VAC and 247 VAC. Once in awhile dropping below 246. The VAC stayed pretty close to 246.5 between the time I plugged in and the EVSC contractors...

Just to note that this setting does not change the voltage the car sees nor does it regulate current. This flips a switch that tells the car the max allowable current. Its up to the car to regulate the current it draws. The only thing the Grizzl-E does is monitor current and disconnects the car...

Thinking there may be a vender sticker on the OBC I tried to look up a parts book photo but all I see is generic stuff. Wow, $20,000+ for a drive unit..

Wonder if the before update behavior is the same. :)

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.

The voltage drop over a cable run varies with the current being drawn. No current, the voltage will be the same at both ends. I dunno how much current the Macan draws during voltage checks, I wouldn't expect much.

Just as a data point, Today I saw 246-247 VAC at the panel (123VAC+ per leg via an accurate DVOM) and was able to top off the charge just fine (Porsche brand wall charger set to 48 amp and split phase). Last I checked many months ago, I was seeing 210-220 VAC and I made an incorrect assumption...

Yeah, didn't want to go into details, but when I think backport engineering I'm including big money and risk for all the testing and certifications, more bug fixes. Its just the way I think as a system architect/lead engineer that routinely explained to business or marketing managers the impact...

Thanks for the clarification, from earlier posts I was under the impression that some grids were out of spec and it would be hard to argue lemon law for that.

Backporting is a common software term that probably only someone familiar with the nuts and bolts of development has heard. It is actually a industry standard, as it can cost big money to backport. Not an easy business decision. It is like moving from hardware that uses ARM processors to...

Is Porsche legally required to operate on out of spec grids? If not, then what is the basis for any legal or lemon law action (the car is not broken)? Asking for a more disciplined/precise German friend :)... One may have to direct legal action at the service provider, I wouldn't expect any...

Christmas tree doesn't seem to be noted here, or is rare. https://www.macanevowners.com/forum/threads/vr28-13-software-update.24409/

There is another thread about problems with home charging after the Macan software update. Seems the updates make the Macan more sensitive to overvoltage. Line voltage can vary from time to time...

Just to be more complete: So called 240 V Real world USA has a lower limit slightly below 220 V. Much of the population actually gets 110V per leg nominal, 220 line to line. Where others here report about 9.5 kW charging rate, I get 9.1 kW due to the lower voltage. Isn't there also a...
