Preliminary update.
Porsche Handen have concluded their tests etc, and found that there is a problem with the control unit for charging the main battery. They could not say anything about the health of the cells or the complete battery now, but would ask the technician If he had any data. The Service Advisors at Porsche Handen have been first class. Knowledgable and helpful

Not sure whether the control unit you were told about is the e-box, which sits on top of the HV battery. Porsche issued a TSB that said: The E-box is part of the high-voltage battery scope. The E-box and high-voltage battery must only be replaced together.

Thanks for highlighting this. They did not say e-box but more like control unit ( styrenhet I think they said?)

But I will ask them. Because in that case it would be a more more serious issue. And would take more time?? Since Porsche DE is involved I hope they have full visibility of the problem. ??

I was just reminded about some crazy rumours about Taycans not liking to be recharge with less the 7.x kW power [...] But again that was scaremongering I felt at that time, but is there some issues there??

I would suggest looking for TI 2706. As I read it, there is (was?) a danger of draining the 12V battery if there is <8A current draw when charging the HV battery. The note mentions that a software fix was expected in 2021, so I would guess that there's a fairly decent chance that the uPdate sorted this out.

Thanks, I look at that but that revers to the 12 volt battery. And I dig not have any problem this Time with that. It was the main tradition battery that seende Fault. The 12 volt sorken gor some Time intill it got depleted and slut down.

I Will ask the SA however? And as you say the major Update was supports to address that issue.

It was the only mention I recall seeing of the guidance to maintain a minimum charging draw.

A quick update!

My car had been transported to the repair hub for the HV battery and work began on the 18 Sept.

The fault had been identified as
1. HV Battery Control unit defective. That control unit is under the lid of the e-control unit in this post
https://www.taycanforum.com/forum/threads/wont-start.15674/page-2#post-243315.
As I understood it that will mean that the battery needs to dropped to be able to access the unit?

2. Two battery modules were identified that needed changing.

I have not been able to see the worksheet with all details as yet , since they are only uploaded once all work is done.

Total time in repair centre was nearly 2 weeks, and the actual work was estimated as 40 -50 manhours. There are strict guidelines for the procedures to be followed and a lot of waiting time, for sealant to be cured, pressure testing of coolants, charging of module, balancing of battery etc etc.

Now the fun has started to get the car back to me. The car is in Stockholm where it broke down and we are at home at the French Riviera, 2500 km away!

The initial call from Porsche Assistance to ask me how I would like to collect the car, was a bizarre conversation.

- ”your car is now ready, when would you like it back?”
- “as soon as possible, please”
- “great, would you like us to book a taxi to bring you to the car??”
- “taxi? The car is 2500 km from where I live!”
- “oohh?”

So hopefully next week they have worked out a plan to reunite us with our car??

One massive learning from this experience though has been that the Extended Warranty from Porsche was extremely worth the money. According to the warranty terms for the HV Battery that only covers the battery! Not equipment around it.

All the repairs around the HV Battery control unit incl. dropping the battery etc had not been covered by the HV battery warranty. Probably the best spent 1300 Euros that I ever spent with Porsche to extend that warranty! I dare not estimate what the total cost of this repair would have costs?

The Porsche Centres in Stockholm have been first class with updates as and when required. Very professional in communications and explanations. I wish the same could be said about Porsche Assistance, but there is a massive potential for improvement!

Will update once car is back!

Final update about the breakdown, repor and transport.

I got a phone call from my Service Advisor yesterday afternoon with good news! The car had been delivered to my Porsche Centre and they had check it up. He said it looked amazing and very clean. And the transport only took about 1 week when they said it could take 1 month. That was very quick and efficient and very appreciated!!

He also read out a bit of the work they had done and he was surprised at the amount of time they had used. It all tallied up to about 50 hours or so. Plus then all the parts. There was a long list of parts but some of them were screws, fasteners, nut, vibration campers and a lot of sealant, plus of course 2 battery modules as well as the HV battery control unit. So quite an expensive repair even if the battery is warranted for 8 years. The control unit and some other parts would not have been covered by the 8 years warranty! And on top of this was the recovery from the underground garage that was complicated and required 4 vehicles in total. Plus of course the initial garage that performed the complete analysis and agreement with Porsche DE for the repair.

My very rough estimate of the repair plus diagnostics is as follows:

- Labour repair 50 hours @ 150 € per hour = 7500 €
- Labour diagnosis 10 hours @ 150. 1500 €
- Parts about Very rough 4000 €
-Towing to garage plus to France. 2500+€
- Our repartition plus taxis. 1000 €
PLEASE take into account that this is MY estimate only based on information given.

This is what I have estimated from the details I have received but I might be way off!!!

If you ask me was the Extended Warranty @ 1300 € worth it?? It would be a RESOUNDING YES!!

Am I very pleased and Happy now??

WELL?? Mixed feelings!

My car came back to my Porsche centre with some damage to my front unfortunately!!

Luckily enough I have full PPF film on and to my laymen eyes it looks like the PPF saved me. The damage seems only to be in the PPF and not the paint.

But now starts the fun of trying to see where this happened?
- At the first tow??
- In the first garage?
- At the second tow?
- At the second garage?
- At the final tow or reloading to France?

But the car is amazing and surprised at the battery stats.

SOH 99%+
Range 420 km.
And all cells are equal balanced!!

Very surprised at the SoH at 54000 km. But pleased with the equal charge level on module level!!

Hopefully the damage cleans up okay. Disappointing that more care wasn't taken. Enjoy your "new" Turbo – it has been a journey and a drama.

From a sustainability, maintainability and recycling perspective – it's good to hear that these batteries can be repaired out in the field at the module level.

The labour costs will have to come down though – but perhaps that will happen through third-party service centres. I'm sure a Porsche Centre flat-six engine rebuild isn't cheap either.

Alll-in-all your experience show us that these batteries are not "throw-away" and hints at a better future,

Yes it is very good that repairs to the batteries can be done. Hopefully the issues were related to a new technology at the start and has improved.

Guess the only way to get the costs down for these repairs would be to have exchange batteries available and then more of a factory environment for the repairs?

But really hoping that these problems soon will be behind us. The car is such a pleasure to drive, when all is well. I have yet to test any other EV that has the same road handling and inspiring confidence on the road. At least not from what I am wanting from a long distance cruiser!!

So literally they only warranty the pouches holding the lithium ion chemistry and nothing else? Everything around the actual battery is not covered? That is worse than when Tesla tried charging customers $1,200 each for 2 gaskets which were required to change a warrantied drive unit. So drive unit replacement was covered, but gaskets were not (and they refused to install old gaskets). Tesla backed away from doing this by the way. Perhaps Porsche has more affluent clientele so they think they can get away with it? Out of curiosity, how much of the replacement of the two bad battery modules was not covered?

Sorry, maybe I was not totally clear in my text. All of these costs were covered by my Extended Waranty (which I took out after 2 year standard warranty period. I do not know how they have split this between extended warranty and battery warranty.

My service adviser just said that the 8 year battery warranty only covered the battery repair, while the extended warranty covered all transports, our repratiation as well as the Control Unit.

In the end I did not have to pay anything at all. Very happy that I was offered Extended warranty!

Thanks for clarifying. I would be curious what the split was between extended and standard warranty cost coverage for this breakdown.

Yep, your experience def reaffirms my rationale for getting my first ever ext warranty !
