Piwi diagnostic program for Porche Taykan

[carlos vilarinho]

Just to be clear, my concern was for your house wiring, socket and a plug, your can can deal with 195V AC no problem. But, if the voltage drop is due to a loose connection in your socket, it could over time damage/melt it - something you would not not noticed in the past because nothing was drawing 16A for 12hrs straight.

Yes, I understand, but that being the case, there is no problem...

Hi Shug ,hope you are well. I wanted to share an update on the diagnostics I intend to perform on my car.

I am still waiting for the 12V battery charger to arrive, I am considering continuing the diagnostic process in the meantime. My goal is to:

Run diagnostics to identify existing issues.

Temporarily clear fault codes to see what issues persist.

However, I am aware of the potential risks of running diagnostics without a fully charged battery, such as inaccurate results or power issues. Before proceeding, I will ensure that the battery has sufficient charge by checking the voltage and minimizing power usage during the process.

I have no idea how long it might take to diagnose the car's errors and erase them, hence my request for information and opinion.

If you have any additional advice or suggestions, I would greatly appreciate your input!

Hi Carlos,

No problem to run the initial diagnostics routine that I gave you without the charger, just be careful to monitor the battery voltage on your dashboard and you will also see it displayed on PIWIS.

With the charger, set it to 14.5V offline before you connect to the 12V battery and it will keep the voltage where it needs to be.

Without the battery charger you should see 13.5V, whitex can maybe confirm what he saw on his car, but do not let the battery voltage drop below 12.5V.

such is a bit absorbed asking.... but more or less how much time is needed from the beginning of the error diagnosis to the end... more or less 1 hour...2...

Sometimes PIWIS seems to get lost doing what it does, you just have to be patient while it completes the routines.

The initial finding of errors should be complete in 10 minutes, the routine to delete the errors can take a while.

The fun begins when you have to work on the errors.

Being able to screenshot the errors to post on here means you will need the Wifi to be on. I know you have seen warnings about this, I never had any issues with the internet being connected, but you will have to make your own mind up about that.

Yes, I saw the warnings, but I have no problem connecting to the internet... I think that first, considering the entire situation after checking the electrical wires and fuses of the car, I want to diagnose the errors, turn them off and see what errors remain and then we will see each situation individually. It could be just errors in one sector or they could be errors in different parts, so let's look at each case individually. For example, I have ABS lights and missing brake pads. It could even be the brake pads that should have been changed by now... The windshield doesn't work. I've already changed the rain sensor and the glass gel and it still doesn't work, but in any case the previous errors haven't been erased... For example, I was able to see in the PCM that the 12V battery was changed about 1,500 km ago, but the cabin filter, brake fluid, etc. were never changed... They could have changed the battery and it's not good. I'm going to do the diagnostics, turn it off and see what happens. ,then we discussed point by point how to solve it…?

 

[Shug]

Carlos,

The effect of missing brake pads may be significant.

Certainly ABS would not work without them.

I would get them replaced ASAP so that you are not chasing ghosts trying solve problems that are already understood.

Shug, yes, I completely agree with you and I also think that the best way forward is to diagnose the situation before making any final decisions. This approach will allow me to better understand the situation and act with more clarity and precision.


I am immensely grateful for your availability and support so far, and Thank you for your guidance and warning, i will arrange for the brake pads to be replaced as soon as possible after performing the diagnostics, to avoid complications and ensure the full functioning of the ABS system.

Once again, thank you very much for your understanding and collaboration.?

What I meant earlier with the example of brake pads and ABS was in the context of failures in a car, it is entirely possible that the errors presented are not related to a single problem, but rather to a combination of factors or even failures in different systems that end up interacting in unexpected ways.

1. Interdependence of Systems:
Modern vehicle systems, such as ABS, stability control (ESP), and sensors of various types, are all interconnected. A problem in one part (for example, a wheel sensor or a worn brake pad) can lead the system to interpret that other components are also compromised.

2. Simultaneous or Coincidental Failures:
A failure can be caused by a specific part or component, while another (unrelated) problem arises at the same time. This can give the impression that the failures are connected.

3. Cascade Effect:
A defect in one system can cause others to enter “safe mode”. For example, a faulty speed sensor can affect the ABS, traction control and even the instrument panel, generating multiple error messages.

4. Electronic Diagnostics:
Since modern cars have many electronic modules, diagnostics can sometimes point out errors that appear to be disconnected. This can be confusing, but it is common when there are problems in communication between modules.

5. Single Problem with Multiple Symptoms:
Sometimes, a single problem (such as a broken battery, faulty electronic control unit, or a poorly connected connector) can generate several error codes, giving the impression that there are several faults.

Diagnostics will certainly help us understand whether the problems are really related or if they are isolated situations.During this period I have read several comments from other owners of these cars with numerous problems of errors that suddenly appear out of nowhere, some similar to others not very different from mine.

You can also screenshot and save to a thumb drive (or save locally then copy to a thumb drive).

just a video that I would like to share here so that you can see the resistance of an electric car to water, of course it is advisable that an electric car has not been exposed to water up to the middle of the rim, but as you can see Volvo for example filled the water car??

This video reminded me of this one:


Sadly, Porsche could never dream of such durability of their battery and battery enclosure. German automakers haven't received the memo about that yet.

Taycan's are known for "red circle of death" which is caused by humidity making into the battery pack.
Taycan is also known as the car that gets tottaled for 3mm dents on the "protective" plate underneath the car, as apparently 3mm dent is enough to damage the cooling system and battery beyond repair.

So I would advise against any durability tests with your own taycan, of any kind.

In asia they do a lot of this "extreme" testing, such as drops from helicopters and being driven over by tanks.

I pressed f8 to erase all selected entries from the error memory and the program doesn't seem to have frozen, nothing... what should I do now...???????

 

[Shug]

Please describe all the steps you have taken to this point?

You can copy the list I gave you and confirm complete for each step

 

[carlos vilarinho]

Information

6.4 Press F8“ to delete fault memory entries.

6.5 Press F12“ ('Yes') in response to the
question as to whether you really want to delete all fault memory entries.

I was in the penultimate step (….press F8 to delete fault memory entries…..) But in the meantime it froze, I waited for about 40 minutes nothing changed and I removed everything, I turned off the car's ignition and now I turned everything back on again I will start from the beginning again to check the existing errors again, delete the errors and get back what is left, I hope it does not freeze again the battery value has always been at 13.5 V

 

[Shug]

The Battery at 13.5V means you should be fine.
