PCM version tracking (and their differences)

[prj]

I don't think they make CE and DD anymore.

CE can not be ordered, it is replaced with DD.
DD can be ordered.
DE can also be ordered.

I asked what the difference between these hardware's are, and the answer was: no idea .
My own asumption, the difference is what software they come preinstalled with (3882, 4360 and 4578)

The MY26 part number is completely different and most likely the hardware is different because Porsche says it has upgraded compute.

It is quite likely that BF, DD and DE are the same part with different software though.

So if I ask Porsche to replace my PCM (CE currently) I will get a DD or DE? Any chances I will get a unit with app center?

They won’t replace it tho’

The reason they do replacements on j1.1 right now is because they have no solution for the navigation issue.

J1.2 has 0 issues requiring a replacement.

Thanks to new hardware, the PCM system is now more responsive. As well as greater computing power, it offers additional capabilities, such as direct access to a large number of third-party apps for native use directly in the PCM.

They also say that they have OTA, and much other bullshit So I wouldn’t trust every word.

It could for sure be newer hardware, but that doesn’t automatically result in compatibility issues. It could also just be more porsche bullshit

Does not say anything about OTA in that press release.
Taycan fully supports OTA though, they just don't use it very often ...

As I said, from my experience the MY26 PCM is much snappier than MY25 while being basically exactly the same from the layout, so I don't think they optimized anything, just added more raw power.

PCM software update last week because I reported the nav/charge related crashes. Only used nav for short journeys since and it hasn’t crashed, but this is different, it was crashing after a few minutes.

PCM software 3885
Hardware H9J1035070AG
Navigation package
V03959817PJ_P1490_EU_2026.02

I’ve been using Porsche’s nav during recent trips, with over 1000 miles in the last 2 weeks including a 10hr drive 10 days ago, close to 600 miles, and no issues thankfully.
