(If you use an iPad to enter a new message, don't switch to your camera, first click save draft. Or else you'll loose all text entered which obviously happened to me)
Since the LTE icon disappeared a few days ago, I tried to solve it by rebooting the PCM.
First challenge was to figure out how to reboot. I had seen messages on the forum, but couldn't manage until today.
So let me try to explain how I did it:
Wait until all icons (more than 9 in my case) have appeared after switching on the car, for example handleiding(manual) appears after a while.
Right after startup:
(Sorry for the lousy pics, but didn't want to wait till tonight).
Menu is now complete:
Go to the first home screen on the center console by clicking on the home icon until you see the house picture and the first of the two lines below it in blue.(Like in the pic above).
Look in (almost) the top right of the screen, you should see your name there and an image that looks like the letter v. The letter v is position 1.
In the top right of the screen I see the temperature, but it is possible to have the date and/or time(?) there. Below it is a phone with a line through it from lower left to upper right. This is position 2.
Press and hold position 1 with your pointing finger and position 2 with your middle finger. The screens should go black. Stop pressing and wait about 10 seconds for the Engineering menu to appear. If nothing happens, lift your fingers and try again close to position 1 and 2. Eventually the screen will go black and you have managed to reboot into Engineering mode.
If your only intention was to reboot the PCM, reboot again to normal mode by pressing the last menu option.

Curious as I am, I clicked on the other three options too.
Activation keys:
I didn't go any further with this one.
Next is version information:
Clicking info showed a list of 27 devices:
Some interesting device names for sure!
I clicked on POWebApps and got:
I didn't explore this menu option any further.
update on the main menu showed NONE. Ok, but how about that Log button in the upper right
After clicking it I got a list of updates that have been applied to the Taycan
So my car got 3 MPR3_ER_POG46 updates, P3267, P3276 and P3397.Probably the WMA stuff. These are PCM updates, thanks ChrisK.
And two online manual updates and a few OTA(Nav?) updates.
Clicking on the P3267 showed another menu:
And clicking each option showed:
The general information for the P3276 update:
and the P3397 update:
The P3397 had "Old" for the MMX3_Patch on device summary:
There are some interesting module names in there, which might reveal which operating system and software is used in our car. I will dive deeper into this in another post.
BTW, the LTE icon never came back, so I'll go to the PC this week.
(Also connect app and myporsche website can't find the car, there are more LTE problems reported on the forum).
