Update of Service Information

Condition
The customer reports one or more of the following issues:
•
The PCM continually and sporadically reboots. Sometimes, the screen freezes beforehand and

disallows inputs for a time, though audio playback continues. At other times, the screen may shut

off and restart suddenly, without warning.
•
Porsche Innodrive does not function. The issue is also sporadic and may continue even after a key
cycle.
The workshop confirms the customer complaint.
Technical Background
These failures are due to the PCM’s memory allocation. The PCM exceeds the allowed allocation for its navigation
system and overruns the computer memory, subsequently crashing the whole system. An upgrade of PCM software
to version 2865 or higher will permanently solve the issue.
This fault is associated with vehicles that have Cluster 26 PCM software. Check the VAL to ensure this level of
software is present before proceeding.

A note about ‘Cluster XX’ PCM software:
Often Porsche will refer to modern PCM software by its first two characters. These characters identify the family,
or cluster, of that software release. For example, Porsche may refer to PCM software version 2865 as cluster 28
(sometimes designated as CL28). The same would apply to software version 2893 and 2812. All are cluster 28 or
CL28. Software 3B05 is cluster 3B or CL3B.

Service Information

For Cayenne (MY19-21 9YA/B), and Macan II (MY19-21 95B), software version 2865 is only available when installing a new PCM at hardware version 058/059.
For 911 (MY20-21 992), only software version 2872 will solve the issue. This software version is only available with
PCM hardware version 061.
After taking a VAL, confirm the HW version to determine applicability and order a new PCM with the latest supersession if necessary. (The new parts have software version 2865 or higher built in from the factory.)
