No System Sounds for turn signals, assistance systems, and parking sensors

[Sparky]

I have a CT4 which was delivered about a month ago. Several days after delivery, I have no sound for the turn signals, assistance systems such as lane keeping assist and the parking sensors. The radio, phone, Apple Car Play, door locking, and even the trunk closing warning signal work fine. The level of sound for the assist systems and the parking sensors are set to medium in the PCM.

I reset the PCM and then, rebooted the PCM with no success in restoring the sounds. I wonder if there is some setting in the PCM that I am missing.

Has anyone experienced this problem? I don't see any threads on this topic.

No setting other than the one you've described.

Sounds like another software fault - boot sequence or similar. Did it per chance rectify itself after locking the car and leaving overnight?

No luck. I am not in a rush to bring it to the dealer. I'll wait until it needs a state inspection. Agree that this is software as I assume the parking sensors beeps come through the radio's speakers.

I wouldn't wait to bring it to the dealer, the sooner they are made aware, the sooner Porsche can issue a "fix" if it is software related. You may also want to insure in your Porsche connect services, that "OTA" is authorized, they will push updates to your car automatically as they modify the software.

I brought my CT4 for the DME software update. The dealer corrected the no-sound problem by pulling the fuse for the instrument panel. If it happens again, I now know what to do.
