PCM and warning signs-

[Peter]

I have received my MACAN 4 in January and enjoying it. However I had a few issues with the PCM giving warning signs at different days. ( they disappear after stopping and locking the car for a while ) I was wondering if Porsche has an updated version to be released .
Attached are some the warnings signs :
Any one has encountered those ?

seems you need an update.

More software bugginess. Did it clear and not reoccur? Had a few weird ones early, but all have cleared and not repeated. If it persist, would get it into service to have them take a look.

Did your dealer configure the car correctly for your location?

These errors can also appear when there is a lot of moisture and / or dust on the windscreen camera and / or parking sensors and / or radar dome.

All look to be related to the headlights which are controlled by the windscreen camera.

i got similar errors 2 days after delivery... they never came back. The only time i had similar errors is when it started raining for the first time in a long time...and I assume the dust/mud on the sensors were the issue, cuz they went away after turning the car off for a minute, and never came back.

I have similar issues with PCM giving randomly some warnings like losing the speed limit signs or infotainment sticking (no radio/music, navi not working etc) and do not come back after reset (pressing down the central knob). It is only coming back to normal after switching off the car for a while.
I noticed that when connecting the car play, the system crashes after a while.
I have an appointment with the dealer on Friday

As I informed in another post I have an official confirmation that this bug will be solved in the next software update at September 2025.

Sharing that there are fixes coming 6 months out is not a confidence builder. Porsche rarely releases this info publicly.
