Assistance systems issues

[aussie1973]

Hi first post (and first EV, though had a Cayman years ago). A couple of months and 1500 miles in? All going brilliantly when suddenly I start getting assistance system issues, see photos.
any ideas greatly appreciated, I’ve forwarded to the dealer too

I randomly get these as well. Sometimes all of them freak out, sometimes just one or two. It clears after you’ve turned off the car for a while. Sometimes might take several hours or more. But always seems to go away with time. Annoying, but taking to the dealer doesn’t seem to help as it usually clears by the time they get it. All they seem to do is clear the codes. I chalk it up to typical Porsche software weakness (their Achilles heal). Same thing going on with my wife’s 2025 Cayenne hybrid.

I have periodically received these warnings as well over the past six months, however these warnings usually disappear after restarting the Macan. Unfortunately, the new software update installed last month did not resolve the issue.

As you’re in the UK, have you arranged the ‘campaign’ they have very recently released for UK cars. I was lucky, my car hasn’t had any issues at all in 3 months, but the dealer called and my car had the software campaign last week. The dealer wasn’t too sure what it covered except ‘some control units & multimedia update’. Might be worth getting if you haven’t already arranged it. It only took a few hours - I think it took longer for them to arrange and do the complimentart valet !

Same issue happened to me. Took delivery last Tuesday, on Saturday morning all the driver assist features had those same warnings. Porsche told me to shut the car off for 20 minutes to see if the errors cleared. They did.

Couple of other “helpers” beyond what is noted above. Not just stop the car and turn it off, but open the drivers door for a few seconds and then close it. And if that alone does not work, hold down on the volume button continuously until the PCM goes totally black — then re-boots and comes back on.

Those two have solved my very rare but intermittent “assistance time outs.” Hope one or both work for you.

Thanks so much for all your responses. I also contacted the dealer - they said to clean the sensors on the front!
