Unusual software issues

[Rembo20]

Picked up our long-awaited 4S Cross Turismo at the very end of October 2023 after a 20 month wait (car left factory in March...). All fine apart from the car being unable to connect to server with red SOS light, so no Porsche Connect/My Porsche remote access - we did query this on handover, but were told it usually sorts itself out after a few days, and by that point we were desperate to take delivery.

Two trips to the dealer later, we collected car on Friday and were told they've replaced the 'Porsche Connect module'. Light turned green and remote access working. However, there are now a host of issues with the PCM which we didn't notice til we returned home:

• No drive modes - we have Sport Chrono and nothing happens when turning the knob on the steering wheel. In the PCM the option is greyed out and it says 'functionality not available'
• No comfort /keyless entry
• No Apple Car Play - the option simply doesn't exist in the menu, but phone does still connect wirelessly
• Matrix lights not functional
• No maps or navigation - says we have to purchase through the store
• No traffic sign recognition
• Electric sport sound not working
• And perhaps the weirdest one - Sports exhaust system is an option in the 'Drive' menu (although greyed out/not clickable)

All very odd. Not sure whether they did the WPN8 update. You'd hope they'd do it at the same time as replacing the module, but the recall notice is still active on My Porsche. Either way, seems unlikely the update would have this effect.

Having waited so long for the car it's frustrating that we are going back to the dealer for the third time in the space of just over a month. Went into the purchase with eyes wide open after reading posts on this forum for the past couple years, but it's still painful. Fingers crossed it's all sorted ASAP and that's it til the 2-year service...(!)

Anyone else had any of these problems after a dealer visit for PCM-related issues?

Wouah, strange issues indeed. Have you tried to reset the PCM with the 2 fingers method?

I'm sorry your car is having these problems.
Before I took delivery of my Taycan a couple years ago, I read a post by @W1NGE who advised:
When taking delivery, do not drive the car away from the dealership before verifying that the SOS light is green and your MyPorsche app has remote access to the car.
It's still important advice for people buying Taycans.

Yep, no luck

Indeed. Was on my list of things to check at handover but had a PPF appointment straight after, so decided to fix the issue later. You live and you learn.

There is complexity for dealers in setting up proper data comm services for Taycans before delivery, which is probably why Porsche issued a TSB about it recently.
Dealers have had practice with this in last two years, so fewer posts about problems with this in the forum recently.

Have they put in a Panamera PCM controller? ?
Sounds like they haven’t coded it correctly (ie set all the factory options that are on the car - like sports crono).
