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...

According to Grizzl-E classic documentation, the basic dumb EVSE has an overcurrent monitor and throws a fault when current draw is more than set by the DIP switches. I think the feature is required to get certified and EVSEs that have that sticker would have something similar. When it throws a...

I have a 4S and recently had a 4 loaner for a day. The throttle response is similar but the 4S is more satisfying, feels more responsive and lite on its toes. The 4S has rear wheel steering and PVT. RWS makes for a more fun drive while a big help navigating narrow city streets and parking areas...

Just a reminder this this 50%/100% setting just sets the EVSE current available parameter that is sent to the car It is up to the car to pull current up to that limit. When a car busts that limit, the EVSE should shut off the charging power (open the power relay contacts).

If your service provider won't address this, I would look at so called power line regulators or conditioners and feed your EVSE with its output. I think 45 amp rated ones are available for about $500 US but require professional installation.
