I’ve experienced the issue with no sound from the Bose speakers in my MY25 Macan 4S twice in the past two weeks and about 6 times in the past three months, despite getting the software update on January 2nd.

I’ve also had two “assistance systems limited” warnings and two “doors will not automatically lock” errors this year.

All of these seem to resolve themselves after locking the car and returning 15 minutes later but it’s still very annoying.

Im going in at the end of the month. They original wanted to replace the PCM, but I guess porsche said to replace the amplififier for my sound issues. I have had recently where one side of the stereo doesn't have audio. but more often it's been this other odd condition:
1) where, parking sensor noises, voice recognition, voice navigation prompts and systems sounds, and even blue tooth phone calls all work (I don't use car play btw)
2) BUT at the same time, Bluetooth audio, AM/FM, XM, all DO NOT work.

I had them scan the car while in this fault condition and there was not a single code in the car.

hope the amplifier replacement at the end of the month resolves the issues. I have had all the other updates including the latest SQ4 update (may 25 2026 release date) applied. Problems have been less often, but this audio issue still happens.
