PCM Software Version Update

a standard DVD-R should have enough space to hold the update. I just completed it last month and everything works fine. FWIW the update does help stabilize the system. My bluetooth audio connection would unexplainably drop every 8-10 starts - it has yet to drop with this new update installed.

Update 4.67 for PCM 3.1 on Cayenne S 2011
Hi, Thank you all for the feedback. I burned the file to a DVD successfully. Software only updating 2 modules. Also, on boot screen it asks me to update to V2.67. It also shows screen that update was done successfully. Anyone any ideas?

Do you have a PCM 3.1? This only applies to that PCM. I believe cars before 2013 were PCM 3.0 and I don't think 4.75 will work with PCM 3.0.

Hey JSLO, my friend has a 2015 Porsche Caymen with PCM 3.1. I am trying to help troubleshoot the reboot loop issue and I attempted to clone the HDD to SSD but the process failed. I ran some diagnostics on the original Toshiba HDD and it appears as though it has failed. Do you have any recommendations on how I might get the necessary software onto the SSD? I tried downloading a software update ISO file but am not able to put that on the new SSD for some reason. Looking for any guidance you might have given your vast experience with this particular issue! Thanks

I tried this on my 2012 Cayenne Turbo. I was on V3.43. Put in the disc, it looked like it was updating, said it updated. Checked the version...still 3.43. I'm trying to find out if V3.xx can be updated to V4.xx, or am I stuck with V3.43 (the latest of the V3)

You can't jump from 3.xx to 4.xx.
