Has anyone tried the class action route with the constant rebooting pcm? I just sold my CD 2014 and it started this problem the day before delivery. The suit says you must be the owner of record back in May 2020. Not ideal circumstances. @ozzythething could you contact me regarding your service with the hd?

Has anyone applied for and received reimbursement for their PCM replacement or fix? If so, did you have to jump through any hoops?

So, I had my PCM 3.1 HD go on my 991.1 and since Jslo seems to have a dead account and I’m not savvy enough to do the HD copying and reinstalling myself, I was left with spending $4,000 (CAD) to replace the entire unit.
Then I saw this video from Driver 81 on YouTube, we now finally have an easy and better replacement that directly replaces the stock PCM 3.1 but with all the added features of Apple CarPlay Android etc… for literally about 1/10th the cost.
I wish this option was around when I needed to replace my PCM and I would have saved thousands of dollars. I’m NOT sponsored, don’t own the replacement head unit but from the video and from looking at their videos on YouTube it is probably the easiest solution for all of us that get stuck with a dead or constantly resetting PCM.
Knowing we have a slightly defective head unit kind of grinds my gears and Porsche is frankly not helpful at all besides looking to reach deep into our wallets.
Here’s the video link to the Erisin PCM replacement unit. I hope this saves people the huge headache and rip off from the dealership.
I hope this helps!

I’m almost tempted to just take the PCM out and replace it with this Erisin, keep the original PCM in the house for safe keeping and put it back in if I sell it. (Doubt I will sell it, only 33k km’s on it - only selling to upgrade).

Yes they got phased out in June 2013 as far as I know..
I will do an IDE repair/preventative upgrade for free (or at cost) to someone who has an IDE drive. Otherwise SATA drives are freshly restocked, anyone having the reboot issue can PM me for a freshly written SATA SSD.
Close to 100 pcm’s fixed with my repair kits![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

this is 100% the way
If without a drive your unit works but loses functionality, you can get a SSD kit from me to restore functionality.
If without a drive it still reboots, that PCM is likely toast…
also, before your HDD dies, I recommend getting an SSD upgrade as a preventative maintenance. Some of these drives are now 10+ years old and it’s not a question of if, it’s when.

aardy,
It is important that you have a good cloned disk and a good update disk. In my case, I cloned my HDD to a 120GB SSD using Clonezilla, but I suspect I did not do a good job of the cloning.. Since I could not obtain a PCM update disk from the Porsche dealer, I downloaded an ISO image from the web and burnt an update DVD.
When I tried to do the update, it put me into an Emergency Update and it was then that I appealed for help from the Forum. Jslo came to my rescue and enabled me to get a good clone and a new update disk. I noticed that this new update disk was not identical to the one I had burnt from the ISO image and contained many additional files.
Ten minutes after inserting the Update Memory Stick on the USB socket in the armrest console, I had a fully working system again, with full funcionality. I was so relieved! Before the fix, the PCM was rebooting every 4 minutes and this was draining the battery to under 12V in only 3 days. Now there is no rebooting and the battery drop is 0.05 V in 3 days. It feels good to have solved this problem during the Covid-19 shutdown and I owe a lot to the smart people on this forum. Hang in there and you'll eventually get it fixed, with the benefit of a more reliable SSD component in your PCM unit. I'm also convinced that the PCM works faster and more smoothly than before.

I'm also stuck in the Emergency Update loop trying to update from 4.73 to 4.76. I tried both a DVD and a USB stick. Can I ask where you got the new update disk from, that has different files from the ISO image that you first used (and is likely what I have been trying)? Will the one from the pcmupdate.com site work, or is it different?
Try a different USB stick - some brands don't work.
I used a SanDisk and it did but the DVD did not.
