Macan EV 4S will not start. Battery at 70% full

Curious if you tried a soft reset by holding the volume knob down until screens go black and reboot. That would be an easier fix to attempt, similar to what Teslas need from time to time.

No - but I didnt know this was a 'thing' either. Which volume knob? The one on the steering wheel or the one in centre console?

Good to hear you got sorted for now, someone needs to do a video to show where this connector is - although not sure I'd be comfortable with all those sparks.

its the one I have circled in red here if you ever need to do it...

Center console is my understanding though still waiting for mine. Perhaps someone else can confirm.

Yes, it's the centre console volume knob.
If you press for a couple of seconds, it asks you if you want to turn that screen off.
But if you continue to keep it pressed (around 20 seconds, I think), it turns everything off then restarts. It's a soft reset, which is needed sometimes to clear some bugs (not all).

Just like your phone, that sometimes you need to restart!

A footnote to this story … I driove the car today and its the first time I have seen the spoiler visible in the rear view mirror. I had assumed (for past 3 months!) that it only raised slightly and hence I couldnt see it. It seems it was never actually working at all, and the ’reboot’ got that going too. I wonder what else has been fixed… or broken … as a result of the power cycle…

I take that back - its stopped doing it again!

Are there two levels of extension for the rear spoiler? When I extended it manually it said it had reached the intermediate point on the display…

CORRECTION: I searched a little further in the forums and found that the sunroof being open changes the level of the spoiler - and extends it higher, making it more visible in the rear view mirror. As this morning was the first day of sun in Manchester, UK since I took delivery on 31st December, it was coincidental with my power-related issues yesterday!

Thanks will need to try sunroof and bigger spoiler

So does soft reset using the volume button mean that all your settings are saved?

How about the hard battery terminal removal reset - does this remove all your settings, phone connections etc?

I dont know about the soft reset with volume button, as haven’t tried that yet.

The recovery driver said that I may have to reset some settings following the 12v lead removal and initially it seemed my wing mirrors didnt retract when I locked the doors yesterday.

I awoke early this morning expecting (and rather looking forward to) having to configure the user profiles again… and absolutely nothing had been lost as far as I can tell. So, it seems like a non-destructive reset thus far.

What a coincidence! I too noticed for the first time, my raised rear spoiler through my rear view mirror and didn't know about the link with the sunroof, as I too had the sunroof fully open on Saturday afternoon, in Manchester. Nor did I know about the soft reset either, which I used this morning to reset my android mobile not connecting.

Over my 6 month ownership and 8K miles, I have had something similar happen twice. On both occasions I exited the car, allowed it to lock itself, then walked back to it a minute later, allowed it to unlock itself, and everything was back to normal.

Ok... here's the update and its good news.

The Porsche Assist engineer (actually an AA recovery person here in the UK) visited my house to look at it. His face dropped when he saw it was an EV and he started to mumble about how difficult it will be to lift the car and get it onto a transporter, etc... etc..

Before doing that he checked his knowledge base and there was a similar case so he tried the suggested action (the equivalent of the Microsoft CTL+ALT+DEL I suggested at the start of this thread) and it worked !

What he did - and I think there is reference to it in one the comments just above this - was disconnect the earth under the panel in the right hand side of the Frunk and kept it disconnected in his hand for 4-5 minutes then reconnected it ... sparks and all. I guess this is what you guys are saying about the 12V battery above.

He also commented that he knows of a few owners of other (non-Porsche) vehicles who carry a 16mm socket in their car specifically for this purpose and it tends to resolve many of these computer-related issues. That all said, I'm not sure I'd want other family members having to do this out in the wild, at night, etc.

Thanks to everyone for the advice. The seat sensors one had me convinced for a while but it just needed the reboot.

Apparently , its may've reset many of my settings to default and I need to go and set them up again. but I can live with that. Who knows... it might even have fixed my mysterious passenger window issues too...

The case in the notes he looked up might have been mine. That’s exactly what the AA man did to mine when it wouldn’t start. I now also carry a wrench (spanner) with me just in case. Never needed it but you never know. Car is in for an investigation of other electrical faults next week so will see if it needs any updates. One running issue is intermittent iPhone wireless connectivity which I would love to get solved cos it nearly always seems to happen to my wife’s phone rather than mine and I’m the one who has to try to resolve it.
