2026 Macan Turbo - Assistance Systems Limited Error

[No_Wonk]

Anyone else experience this error on their Macan? This basically disables "Assisted Lane Change" and "Trained Parking" as far as I know, Drive Assist still works.

Service department said the solenoid for the charger port went bad and triggered this error. They didn't have the part in stock so I got the car back while I wait until they get it.

When I got the car back there error is now gone and been good for a week so far.

Is this just buggy software, or could it actually be a real issue?

This has been reported on elsewhere in the forum for all MY. Buggy software. Also GPS eventually shows an offset following these errors. Sometimes resets itself with a matter of days. No known cause as yet. I seriously doubt its root cause is related to a bad charger port solenoid.

This happens about once per week on my ‘24 Cayenne S E Hybrid. Goes away the next time the car is turned on. Just appears to be something not responding quickly enough for the initial check of all systems, not an error per se, just modern vehicles doing what they do (happened on my BMW often too, so not just a Porsche issue).

I get that like every morning for about 3 min. with Lange departure and others.

Our MY26 Macan GTS EV has a problem with the driving assist where it has never adopted speed limits despite the car recognising up coming speed limit signs.
not had any issues with any other aspects of driving assist.
My local dealer has had the car in, seen the problem and referred it to Porsche Germany as they are stumped..
I wouldn’t mind but speed limit adoption is always my first option on any car. Previous BMW iX had it and it worked flawlessly as did our PHE GLC de Mercedes.
I’m UK based

In the US we can permanently disable the speed limit speed auto change, so I've never tested this because I find it annoying that the car would slow down when the speed limit drops.

There is certainly an option to have automatic adoption of speed limits on or off.
mine doesn’t work on either setting!

haha "off" definitely works because it's not working for you.
