Hmmm ... is this particular device/capability something that should "simply" be removed? Would removal void the warranty on those cars under warranty? Would removal increase insurance costs?
Sure, there would be less security, but perhaps this is offset by more reliability, especially given Porsche's uncaring response both in parts and loaner cars?

Not sure if this document was posted, but maybe some can glean more info from it. It looks to be different than the one posted above.

Well you seem to believe there is no correlation. Please explain what is failing that's immobilizing these cars. Is it the VTS module? Seems there's a crossover of systems and the VTS module is part and parcel of this. Is the VTS module in every car? People who have posted here with the issue said they are not subscribers to CC and CC+ and never have been. The 718Forum.com has multiple reports now and they too are not subscribers to the services. So what exactly is happening?

Correct. There is currently no data present that supports any sort of correlation. What you're specifically responding to and asking, I believe, is correlation between the optional module update TSB issued late last year. There is no correlation between that and these module failures. If there were, the update would not be optional.
Yes. That's the whole purpose of this thread.
Yes, the VTS system is part of the immobilizer system, as mentioned numerous times in this thread.
I do not believe so. It is standard equipment in the 991.2, but within this thread it is mentioned that it may be an option in the 991.1, hence my very first post in this thread theorizing that it could be coded out.
This is unrelated. Just because the module happens to deal with cell service doesn't mean that the only way it can fail is losing cell service. Chafing wires, voltage spike frying chips, getting wet or being in a humid environment for too long corroding connections.. could be any number of very standard, very common electrical failures.
The VTS module is part of the immobilizer system.
If the VTS module electrically malfunctions or, per an earlier TSB, has a software fault that erroneously triggers anti-theft in response to certain vibrations, the immobilizer system assumes theft is happening and activates.
Again, this is because the VTS module is part of the immobilizer system.
The same thing would happen if you violently ripped it out of the car -- your car wouldn't start because the car can't talk to it, and because your car can't talk to it, it assumes theft is happening.
This has nothing to do with the availability cell service -- for example, people who park underground or live in mountainous regions or river valleys don't have this issue. This has nothing to do with being subscribed to car connect, as evidenced by people experiencing module failure who are not subscribed to car connect.

So it's all just coincidence that these failures, which we've never seen reported here and for which these TSBs have recently been released, are occurring now with the sunsetting of 3G? That is your position?

I guess we'll all find out soon enough if the 3G sunset is due to complete nationwide in June.
A failure like this would be a massive face palm and embarrassment for Porsche.
It's really hard to believe it would be designed this way, so I doubt it's just unavailability of 3G cell service, but unavailability of 3G + something else... maybe?

These failures are unrelated to the earlier TSB for 2010 and 2011 models with a software bug that interprets certain vibrations as theft.
The sunsetting of 3G is unrelated, and also hasn't actually happened yet.
My position is that there is no data correlating these things and that it is completely unreasonable to think that a lack of 3G signal causes this module to brick the car.

A touchy module malfunctioning at the start of the driving season? More common than you might think. Look at ten year old BMWs. Simply disconnecting and reconnecting the battery or hooking up certain scan tools carries the risk of frying the forward body control module on a bunch of models between something like 2004 and 2015, it's a whole hilarious thing.

The module will not inhibit drive if it does not have a signal, the problem described here is when the module does not communicate with the rest of the car.
While Porsche makes some ridiculous mistakes you can park on an underground garage and get out of it (luckily).
