EU/UK: Ongoing navigation issues

[Matt-Taycan]

as i mentioned in an earlier post... i've been having all the Sat Nat related issues. Car is booked in tomorrow to have the PCM replaced (sceptical that this will make any difference)

In addition to this issue, i was awoken at 5am today by my car alarm going off, followed immediately after by a phone call from Vodaphone, informing me that my 12v battery was dead. Long story short... Porsche assist came out within the hour to jump the electronics back into life so that the frunk could be opened to access the 12v and jump that. The car then proceeded to behave in perculiar ways, turning itself off when ordinarly it wouldn't, locked itself with the key inside (had to get my spare key and manually unlock it

Charge state was at 86% when this all happened. Have now charged to 100% and left it plugged in

No idea if the PCM/Sat Nav/12V issues are related somehow. The dash is showing 12v state of charge at 13.8v but PCM still gives me 12v low battery warning

to jump the electronics back into life so that the frunk could be opened

How did they do that?

How did they do that?

Cheat sheet: How do I recover my Taycan if it dies because of the 12 volt problem
Also see videos on YouTube.

Thanks All the instructions I have seen start with "open frunk" (and there is an elaborate procedure for that). The quoted premise is different, hence my curiosity.

 

[Matt-Taycan]

How did they do that?

There's a port in the drivers side fuse panel (panel pops off next to your accelerator pedal) Its a small Red connector with a picture of the car/frunk on it. Connected to that and neutral to the bodywork. Key was then enabled and allowed the frunk to be popped

Found an image online. Pretty much sums it up

Following investigation into my sticky sat-nav by Porsche Smartmobility UK at my request - They passed it onto Porsche Germany about 2-3 weeks ago ... Just received this back from Smartmobility.....

"After further review, PAG have requested you take your vehicle into your local Porsche Centre to have the TI 65/23 (software update) performed and the PCM updated to the newest version" - Goes in on Feb 20th - all day.

They will also change the 12v battery sensor while it's in.

Will let you know how it goes. Cheers.

Too soon to tell I'm afraid. I used the navigation to go back home but it's too short of a trip.

Going for a longer, 200 km trip tomorrow though so that will tell me more. Obviously, will let you know

So after 300 km, the turn by turn satnav is behaving as it should, which I must say is so great when it works. No freezes so far and the route recalculating has been fast, which is a change (I deliberately took often other routes to trigger recalculation)

I'll keep testing and report as I go.

Had this exact update performed today including the 12V battery sensor. According to the dealership they have had success with this update in fixing the navigation. After 20km so far so good but will test further in the coming days.

Thanks Skip - thats encouraging at least...

Could you get more info about "12v battery sensor" when they change it?

If it is hardware, where is it located? Is the sensor a subcomponent of some other ecu?​

If it is software or firmware, where is it found?​

Sure Mr. T, will try to find out and come back to you - it's not for a few weeks yet.

Sure Mr. T

You had the Charge Planner on?

 

[Eltibouron]

You had the Charge Planner on?

It depends what you mean by that. PIRM is always on. However, I didn't need to charge for this trip so it didn't add a charging stop

 

[ovonrein]

I meant .../Charger Planner/Active. That feature seems to cause all the issues. Without Charge Planner, the nav seems to behave itself for most people. Probably related to the immense number of HPC in Europe. The nav can't cope.
