EU/UK: Ongoing navigation issues

We are all customers. Regardless of whether we have insider information, everything being discussed in this thread is speculation.

Has anyone tried without LTE or with privacy mode enabled?

Now my LTE is broken I’m going to try the nav on my trip tomorrow (I’m also stuck on guest mode after a reset of the PCM and not able to log in) - I do the same trip often and it always crashes. Wonder if it’ll have any effect

Without LTE you have no data connection right? The nav uses that for real-time traffic and charge planning info so unless Im missing something it wouldn't test for anything?

It might not crash? Which might further show it’s a data overload from live data rather than the navigation itself

Ah, Im sure you'll find it wont crash, for me turning off charge planner is sufficient for it to navigate and not crash

From personal experience, I know that when my Taycan lost internet radio, news, weather, etc. the ability to search for POIs and charging sites in the navigation system also failed. (In my cases LTE was still shown as present.)

If the navigation problem is related to the car's online access to charging sites, my guess is that no LTE will eliminate that source of the problem.

I’ve encountered this issue with my LTE phone. My dealer promptly resolved it. I described the issue in detail about 10 pages ago. You could also try a 12V reset. It’s one of the three communication systems that had errors and is causing other issues. I remember it correctly.

It is obvious that the world's best software cannot overcome faulty hardware

How's the hardware faulty?

The main hypothesis (no, no one here can muster anything better than that at the moment) is that the hardware is running out of memory due to loading to many POIs in the screen.

If that is the indeed the case, then I can tell you: fixing this via software is actually the proper way to do it. The hardware fix, which would be throwing more memory at it, is just a bandaid on a haemorrhage.

You'd be surprised the things that can be done with VERY limited hardware resources. The problem with most consumer-grade interactive-rich software these days is that it's built upon frameworks running atop of more frameworks. So developers end up coding against multple layers of abstraction over the actual hardware.

Needless to say, there's no free lunch: abstraction layers decrease development time-to-market by simplifying software complexity at the cost of weaponising hardware resources.

So if Porsche were serious about this, rather than giving you another 128GB of RAM, they'd look into resolving the multiple memory hogs their software is claimed to have. This can and should be done. Barring that, the next obvious consequence is that the additioanl 128GB of RAM will also be exhausted by loading even more POIs in 2 years.

But let's remember: all this is based on hearsay and hypothesis. Truth is, no one knows what's the root cause of this behaviour. So any claims are baseless without official communication thereof.

They won't even look at the car until towards the end of March, and that's only for an update to 3885

A thought just occurs. The TSB for 3885 mentions very specific pathologies (three, from bad memory)which are outside those discussed in this thread. If you can explain to your OPC that you experience none of the pathologies in that TSB, they may try a PCM swap right away.

Your certainties (about everything, it seems) are entirely misplaced.

My certainties are from mobility developers at porsche cluj, university colegues of mine.

Feel free to not believe me, but don’t give me your attitude about somehow exaggerating the issue

between the 2 of us you are the one misrepresenting the situation, not me

I have my nav set to North Up and it still often freezes and crashes with charge planner enabled. It still crashes with charge planner disabled but much less often, and the left hand navigation thread that shows traffic holdups, road works etc continues to freeze.

Fortunately, the car is heading back to VWFS on Thursday so I won‘t have to worry about useless nav services or the usual Jan/Feb 12V battery issues any more…

 

[Jasper4S]

anyone here with a Skoda EV? There was a rumour couple of weeks ago Skoda EV's had the same issue. Curious if that really is the case. Because that could also suggest it is a backend thing

They might, but at this stage they’re still claiming that they’ve never known or heard of anyone else to have navigation issues so they’re going to have to figure it out bit by bit.

It's not the hardware when the MY25 cars have identical pcm hardware and 4360 does not have the problem.
It's no the hardware when people had the PCM exchanged to the identical one from MY25 and the navigation crashed right away again on the older software version.

No, it's a pure software problem, and the reason it's not being fixed is because Porsche is doing very badly financially and probably can't afford to recall all of these cars for software updates. Since they're out of warranty, they don't have to either.

However, according to reports this issue also disconnects the innodrive when it occurs, this could be dangerous, but of course all the driver assistance features come with disclaimers that they could fail at any time.

The only way that Porsche gets forced to resolve it, is if there is an actual safety notice due to the Innodrive disconnection. However, because this error mostly affects mainland Europe customers, and we don't really have a federal agency here that is dealing with these things, then the likelihood that Porsche is forced to do something is very low.

I am sure if it starts crashing like crazy in the USA, then there will be a forced recall very quickly, because in the US you have a federal agency aggregating this over the whole country.

God that's a cheery outlook @prj. If they aren't going to fix it without the law they're descending into bullshitting customers. Like others my Porsche Centre have said (only yesterday for me when I dropped the car off) Porsche are working on a solution for June.

Could be true, but why;
- did they release 3885 for minor issues. You can only get it if you complain enough.
- are they accepting costs of loaners from all Porsche Centers that are helping us right now.
- are they approving PCM replacements to check if it mitigates the issue
- did they release multiple small patches past 6 months to try to solve it
- did they introduce this bug through an OTA. A recall + visit should not be needed

you are speculating like the rest but you state it like facts. Could do more harm than needed
