Upgraded PCM 3.1 Hard Drive to SSD

dan_189,
After removing the HDD, the PCM booted up and I had the same functionality, only this time the CD player would load and start to read the disk but would not display or play the tracks. The rebooting every few minutes remained the same. I got identical results with the cloned SSD inserted in the PCM. When I reinserted the damaged HDD, I regained the use of the cd player.

I think that if you're getting constant rebooting then the issue might be more sinister than the hard drive. Thoughts @kari ?
Also I'd extract the ISO to a USB if your car has a USB drive - it's more reliable in my opinion.
Sounds like your PCM might have an internal electrical issue.

Agree with dan_189, many of the cases where the unit reboots just after the logo is displayed have hardware or firmware problems. But if the unit is rebooting after 3-4 minutes, then there is a good possibility this is HDD based. Many embedded systems or RTOS based devices (real time operating systems) are programmed to restart on detection of any anomaly that its not setup to handle. No way to know without trying to run the update disk. The update disk reloads all the firmware (OS components, drivers etc) except for some core data specific to the unit like licenses etc and it also loads the data in the HDD (Except maps). So, even if there is filesystem corruption at the firmware level, a reinstall using the update disk should resolve it. Or atleast we will know where the corruption is. But there is the possibility of a hardware/FPGA issue if the problem persists despite running the update disk..

dan_189 and kari,
Thanks for your inputs - I will attempt to do the update in the next few days.
One point of interest, that may or may not be relevant, is that this problem first revealed itself the first time I started the car after the expiration of my Porsche Car Connect Service. I received a notice from Vodafone that my Car Connect 5 year Service Contract was about to expire and would be turned off if I did not renew.
I did not renew and the next time I used the car, I checked my Porsche Car Connect App and found that it was no longer active and the car location and other details were no longer available. Then when I started the car the navi failed to load the maps and I also lost the jukebox. The "rebooting" cycle also started happening.
Perhaps it was a coincidence that my problems started at that point in time! In the prior 5 years there had been zero problems with the car.
The other observation of note is that the regular "rebooting" is more akin to a power cycling of the PCM and is not accompanied by a display of the Porsche logo, which I do get occasionally on startup. It seems that the power is briefly disconnected and reconnected every 5 minutes or so and the PCM audio always resets to FM preset 1, with the volume set at a fixed level.
It almost seems that the PCM is trying and failing to load data from the HDD and keeps repeating the attempt every few minutes. Since the overnight battery drain also seemed higher than usual, I turned off the ignition, sat in the car for 20 minutes, and could hear a double extended click sound from the PCM every 5 minutes even with the car shut off and the PCM display blank.
I strongly suspect that the power is recycling to the PCM all the time, even with the car not in use. I have currently pulled the PCM fuse and have the battery on trickle charge until this issue is resolved.
Perhaps these observations will throw some light on the problem and hopefully the firmware update will improve the situation. Unfortunately, I studied mechanical engineering and my electronics diagnostic skills are very poor.

Anyway, the more you explain the problem, the more I suspect file or filesystem corruption on the HDD and this is not resolved by just plugging a cloned SSD in. You will have to run the update DVD after burning the disk using the iso image from the earlier link. If its just file corruption or filesystem corruption within the firmware, the update should be sufficient to get back full functionality (except navigation as any file corruption of the navigation files requries a reinstall of the maps - you dont have to buy a new license key unless you are upgrading maps, but you will need the dealer to reinstall the maps that you already have a license for if you want them back). If during the upgrade you get a 'Emergency update' screen, then you will have to read the rest of the thread on the emergency update that I shared. There was a similar case where the update failed due to filesystem corruption that had to be resolved before the update could complete...

Kari can you shed some light on the maps for me please? What does the verification of the map code? My car only has a GPS signal and I don't have a sim card in it. I have seen the upgrade process where you enter a map code via PIWIS2 and then load the maps via disks. What validates the map code?
I'd like to upgrade to the latest 2018 maps - was the whole reason for upgrading the HD + software in the first place. I have a PIWIS2 so don;t need to pay the dealer to load the maps but i'm curious about the key validation.

XM crash
Thanks so much jslo73 ! - I was sure HD was shot, but reset PCM 3.1 as recommended and normal radio works and CD's. Ran for over an hour with no crashes. Do you know how I can get around XM crash? - I have not restored service to it yet - lost code when reset, but wanted to have solution before hooking back into service. PS I have V3.43 on my 2013 Panamera. Can I go straight to V4.76?. I also tried following a couple of links to purchase the DVD, but none seem to work (maxspeedmotorsports). If you could direct me to site to purchase it would really appreciated!

Bad news -- My PCM was working great with a new SDD that jslo helped me with this winter. Now, only a few months later, it has started re-booting again, as before!!! Briefly had a 'low battery' signal come up but it hasn't returned. This was the prelude to my first time losing the PCM. Battery was replaced then (4 months ago). HELP!!! WTF Porsche? Another odd thing I've noticed. Even if I power off the PCM, it will still reset itself after 5 minutes and turn on. Repeatably. Ideas?
Update: it was the Sirius XM thing. Thanks Jason for sending me the tutorial on resetting.

5/24/20 - JSLO rocks !
His tip to 'Reset the PCM System: Vehicle Handover' has solved the problem with my 2013 Boxster S (PCM 3.1 w/ Sirius XM).
The PCM was frequently turning on by itself (loud AM!), and so driving was quite unpleasant. Was steeling myself to try a hard drive swap when I spotted JSLO's 5/20 note shown at bottom.
Thanks, JSLO!
Next quest: I will move this related problem to another thread: During the "PCM crisis", the battery completely drained in two days, sitting in the garage. Can a gremlin PCM drain battery? Jump started it, and see "Steering Support Limited. Possible to drive on". Tried all the tips to reset the "steering angle sensor" but no luck.
Need a PIWIS reset by dealer or possible damage to the module?

Start car or just turn to "accessory"

All preset and bluetooth settings will be erased as well as saved addresses, and any music on your jukeBox, but it will stop the rebooting issue.

You still in the PCM upgrade business
Having the same problems with my PCM in my Cayenne. Ordered a SATA SSD today and will attempt to swap out. Any suggestions on where to get the PCM upgrade disk?
Thanks.
Thanks.

I am also looking for the PCM 3.1 upgrade disc. Where are these available? I think my problem is the XM thing, but I'm still wanting to replace my hard drive with a SSD unit before I have any problems...

Try here. Another member gave a link to an .iso ( PCM upgrade 4.76 file) for dl then burn to DVD.
Several members reported success. Look for that in this thread:https://rennlist.com/forums/991/1055...-common-3.html
or

Any tips for Mac OS users? I figured since Clonezilla was a GNU/Linux distro that I'd be able to make a bootable USB and just restart via EFI into Clonezilla to mirror over my PCM drive, but it doesn't want to see the USB upon boot, and after looking into it more, it seems that Mac OS doesn't seem to like Clonezilla USB drives overall.
I have access to a Windows laptop, but wanted to see if there was a way to just do this within, say, Terminal or something before moving on to that.
Edit: this is also the nerdiest thread I've seen here so far that exists at the intersection of automotive repair + tech troubleshooting. This is hitting all my geek receptors, I love it.
Edit 2: running dd in command line right now and it seems to be doing the trick. Fingers crossed.
