The PDK update provides less lag/hesitation and holds gears better in sport mode. The PCM update fixes some bugs with bluetooth and music.

PDK control unit
Information:
This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles.
A shift rod movement at a shift gate that was not selected can be detected incorrectly on the affected vehicles due to a software error.
As a result, fault code “P1767 – Hydraulic multiplexer fault” can be stored in the fault memory of the PDK control unit and the PDK transmission can switch to the reduced driving programme until the ignition is switched off and on again.
To prevent this from happening, the PDK control unit on the affected vehicles will be re-programmed with an updated data record.
On vehicles with Porsche Torque Vectoring Plus (I-no. 221), the updated data record was also used to optimize the adaptation behavior of the rear-differential lock.

Go to INFO then OPTIONS. Once there, you will see System Version. Touch it and the current version will be displayed.

I asked my service advisor what the update actually did and his response was " Porsche tells us nothing, like Apple when it does updates!" LOL
