PCM volume not working

[leasky]

Took my 2015 991.1 GTS for a run today and noticed that the PCM wasn't performing as it should; no volume, unable to play radio or CD and turning itself off and on every minute or so.

The Sat Nav worked as it should as did the phone but no joy with radio or CD player.

Any thoughts gents?

Thanks,

Colin.

What software version do you have?

Thanks for getting back to me. I think its whatever she left the factory with as I have not updated it.

Sorry I cant be of any further help with that one.

Colin.

I think if you scroll through the the menus the PCM software version is displayed somewhere. Worth doing so that someone may be able to help you.
Best of luck with a solution,
Mick

Have you tried a full reboot and Factory reset of the PCM??

* Reboot - - Press and hold info button for appx 10 secs.

* Re-Set - Complete reboot above first. Then press Car, Option , Select Set, PCM system, , select Reset PCM, , Vehicle hand over, Select Yes, then Yes again . This will delete all of your radio saved stations and bluetooth settings and reset the PCM.

* To check software version press - source & info buttons at the same time.

The full reset should fix your problem.

My volume control on the pcm (2015, 991) is turning but the volume isn’t going up or down, does anyone have a fix? There is noise, speakers working etc, just not adjustable. I’ve done a reset but still the same issue. Thanks

The reset you mentioned, did you do this ?

Press and hold the PCM info button for approximately 10 seconds until the PCM reboots.
Immediately select the following from the PCM CAR > OPTION > Set PCM System > Reset PCM > Vehicle Handover > Yes > Yes


option 2 is a hard reset
Hard Reset. you will need to disconnect the negative battery terminal, leave for 15 mins then reconnect.
