Piwi diagnostic program for Porche Taykan

[Scandinavian]

Sorry for your experience with buying a Taycan.

As alteady said you will not be able to just erase the fault codes. If the underlying problem has not been rectified, the message will pop up again, and rightly so.

As I understood this you bought the car in Netherlands and transported it to Polen? Did you inspect the car beforehand? And test drove it? Or unseen?

I guess this was not a Porsche dealer and no Porsche inspection beforehand either. I can understand that it might be desirable to import a car, but I would not go near anything that did not go through a manufacturers inspection. At least then you would have an appreciation of what needs doing to the car?

And the fee for a full test report can easily run to 600 or more Euros for such an inspection, but then you would get a full written report.

I am surprised if the seller did not know of a lot of theese problems already. Do you not have any chance of returning the car?

Yes, I did a test drive in Holland and the car already had a light or two on the dashboard... unfortunately I believed it was nothing special, especially because the car hadn't been crashed and there was absolutely nothing damaged on the outside, just a broken rear door panel and a broken window that had been vandalized. When the car arrived in my hands, I bought the parts that needed to be replaced and I thought it would be a good idea to go to Porsche to do a diagnosis to erase the errors that had appeared on the dashboard in the meantime. The car charges and runs without any problems... no, I have no chance of returning the car because it was sold without any warranty (unfortunately).

No, the Porsche dealership did not give me the complete diagnosis!!! I thought it would be a good idea to contact someone who works with the Piwi program and with Porsche and I scheduled an appointment for January 2nd for a second diagnosis, but this time I already asked the price... the price is around 70 euros, after the diagnosis there may be a possibility of them fixing the car for me... let's see how it goes

Everything that the Porsche service mentioned to me previously and until now were just assumptions, nothing more than that, absolutely nothing concrete, they don't have a history of the car and as I put some new plastics in the car, they refused to do any service on the car beyond the diagnosis they say they did, in fact today I was talking to a person at the dealer's Porsche service who told me that it could be that the 12 V battery could be damaged (the car starts the 13.4 battery fine) he also told me that the high voltage control charger (obc - message missing)….,maybe had to be changed and it will have to be changed by someone qualified because it requires tools to do it and that because of that the whole car could be with high voltage electricity so for someone to analyze the interior wiring it will be necessary to know for sure if there is electricity in the car , say this can be possible because a few time a go they have one Taykan happened that the car have high voltage in all the car, they have to put the main battery in service mode with piwi ,well I previously when the car arrive to me and before I put the car in Porche for diagnostic I made same changes some plastics are damages and I touched the wiring inside to the car several times and disconnected at least a few times the negative pole of the 12 V battery..take the seats out put in ….. and nothing happened, (the car is charging at least until today) because an error appeared, it also mentioned that the main battery does not show any damage…..but all this is just guesses of what will be and what could be…

No I can understand that you did not get the complete diagnosis. I guess that is not what you asked for, but I think the dealer should have offered this? Look up Porsche website and you will see that their second hand cars can have had a 111 point check.
https://www.porsche.com/central-eastern-europe/en/approvedused/porscheapproved/111pointcheck/

The link is probably just generic one and includes spark plugs and exhaust, but there is one for Taycan as well.

I understand perfectly what you mean... but as I mentioned, the dealer did not give me any concrete information about the diagnosis and did not give me the entire diagnosis. The photos of the diagnosis that I presented here previously were photos that I was allowed to take because I went to the dealership for the second time to complain that the way they proceeded with me was not the most viable way for a premium dealership like Porche representative and I said that the person who had called Porche in Porto in Portugal to ask if this was standard procedure for Porsche, which in Portugal immediately replied that it was not. In fact, he told me to file a complaint with some national consumer support institution in Poland or send a complaint to Germany to explain what had happened. When I mentioned that I had contacted another Porsche service in another country to ask if this was standard procedure, they were more friendly and I already tried to help, hence the photos of some parts of the diagnosis. The person who let me take the photos was not the same person who did the diagnosis and who gave me the invoice for payment, because the person who diagnosed me was more concerned about what had been changed or not previously in terms of plastics inside the car... anyway...

I've seen on this forum some people with the same errors as my car, but then nobody says how they fixed the errors...! For example, my front windshield wipers are not working, I changed the rain sensor gel because initially I noticed that the gel was only stuck to the glass and not to the sensor, I cleaned it with alcohol and ordered the gel and a rain sensor and just in case I changed the sensor, even so it still doesn't work, when they did the diagnosis they told me that the front windshield motor works and that maybe a broken wire or it could be the gel or the sensor that may not be in good condition, once again just assumptions...!

I didn't mention that I had put new gel and a new sensor on the glass...!!!!! It is worth mentioning that the rear windshield wipers work perfectly and that the water jets both rear and front also work normally...

Porsche will not tell you what the issue is and let you take the car - that's not how they work. If you want them to fix it, bring it to them, and they will fix it. It will probably result in a 4-20k bill. And there's that. That's how Porsche works.

For a car with so many electronics as the Taycan, I would never endevor to buy one without warranty and not extend the warranty until I am done with the car...

Good luck with fixing the car

I'm not going to take the car to Porsche anymore. I think there could be other alternatives other than Porsche so that I can fix the car. It's obvious and it's clear that they're not going to tell me anything about the car, that is, you pay for a service and they don't even give you what you're entitled to, and you still pay a lot and a lot! I'm not going to deal with the car's faults in that direction. I did what had to be done. There are more unofficial garages that work well with this type of car and with Porsche at 1/3 of the price and are very competent. You just need to find them, that's all! What surprises me is the way they've adopted it. It's not fair and everything is in the sense of meeting the customer's needs so that the customer says, OK, I want the car fixed at any price.... I'm not going to go there, I bought the car at a good price and I can fix it calmly and relaxed, I don't need it for my day to day, so... in fact, as I mentioned with Porsche it can be a simple thing or it can be something more complicated, but everything can be fixed, I have time and I'm not tied to Porsche so that the car is in good condition, even because the basis for fixing the car is the diagnosis and it's not just Porsche that has the Piwi program! In fact, as you mentioned before, the little information I got shows that this could just be something in a sector of the car that declares several errors... Chun, I really appreciate the help, comments and information, just an aside, not all official Porsche dealerships work in the same way, I think in this one that in addition to taking money, they don't give the customer the service that the customer paid for and that's not at all pleasant….

You're talking about guarantees here... I've seen in other cases that Porsche has been trying to reduce the guarantee periods on these cars more and more, in some cases cars even spend months at Porsche and the guarantee has already ended... anyway, is the Porsche guarantee worth it????... I honestly don't think so...I bought the car and it is completely paid , so now I just have to find someone who is honest and trustworthy and can fix the errors in the car at a reasonable price for both of us!
unfortunately I can't say the samefor the Porche dealership here, They weren't honest with me or how they handled the whole situation.

but Chun I have to agree with you in one statement I recognize that... they would never tell me the entire result of the diagnosis nor what the cause of the problem would be, because they know that immediately afterwards I would take the information and go somewhere else to fix the car... (it's as clear as water), anyway I'm going somewhere else to do the diagnosis and I'm going somewhere else to fix the car!

Sadly, that’s how dealership garages operate. The data gathered is likely owned by Porsche AG and has limited access, restricted to “certified technicians”. Another practical issue is that they might expose themselves to commercial abuse (as you have acknowledged) and/or potential liabilities.

Turning off the error/warning lights and sending you off isn’t going to happen — no official dealership will do it, as it’s fraudulent and/or illegal.

Proper troubleshooting must take place to discover and fix the root cause(s), and there’s a cost associated with that.

Your expectations aren’t reasonable.

You’ve got yourself a white elephant.

A. Mayor wasn't expecting them to simply turn off the lights and send me away, I was expecting a paid diagnostic service and to be given the result of the service I paid for, and to be given a minimum explanation of what would have to be done next, now in addition to commercial abuse, I pay for a service and leave with nothing, and to solve the problem I have to go to another place that is not an official Porsche in order to have costs again if I want to solve the problem!

It is not possible to turn off the warning lights without solving the problem in the car, the diagnostics are done and the errors are found but the problem is not solved, that is the problem, I do not even know which errors were erased, in fact I even think that they did not erase any errors and therefore I also do not know which errors remain because this information was not given to me when it should have been.

I am sorry but this car of yours looks like a real Dog’s Breakfast.

You see a car for sale in Netherlands at a very attractive price.
I guess with a private seller, certainly not a Porsche dealer and it does not seem to be a reputable dealer either. Not even a RTC guarantee (Round the Corner)
You test drive it and see a number of fault messages. But no explanation.
You have problem with the lining of the door and a window that has been damaged.
You do not get any history of the car at all it seems.
And you buy the car without getting it inspected by a Porsche dealer.

The car is transported to Poland and you wish the Porsche dealer to erase fault codes so that you can get the car registered in Poland. That sounds totally illegal when you have so many fault codes without addressing and fixing them. Porsche will never ever do such a thing. They may reboot the car with PIWIS to an original state, but not erase anything that remains

If you look at your screen shot you will see that you have some serious fault codes
- 12 brake electronics
- 8 suspension
- 8 high voltage battery
- 11 gateway
etc etc . In total they discovered 149 fault codes you say.

The car should have been serviced twice (every 30 k km), do you have a record of that? And was that done by a Porsche centre?

If a Porsche centre did the service, maybe they can give you some information what has been the status of the car at these stages?

Perhaps the car has been completely flooded so the electronics are fried? Or perhaps been involved in a crash, written off by insurance company and supposed to be sold for spares?

All sounds very bizarre to me.
