Yet another electrical system error - ARB6 software in action?

[KK34]

Appreciate you all sharing your experiences here. II just got the red circle last night on my 2020 Turbo - it got towed in this morning and I am currently waiting for more info on what they find. When I called the SA about the drop off I told her that I had heard that module replacement would be a weeks-to-months type of timeline. She responded that the times are better than they had been, but that it probably still was a multi-week issue.

Sorry to hear that
From my own observations-
The diagnostic procedure seems like it can go quickly or take a few days. Seems anecdotally like waiting on parts is biggest variable. The repairs (if it goes correctly the first time) were about a week with testing procedures. There is all sorts of waiting time involved with the sealing goo curing, leak validation, charge / maintain / discharge / maintain / repeat testing tasks, etc. Without knowing how quickly your dealership will get the parts makes guessing difficult. Sub-2 months would be the bar IMO.
Best of luck, and hopefully you see the fast side of the bell curve!

Appreciate that - picked up the loaner a few hours ago and they were at least able to get me into an electric Macan. SA didnt yet have all the details, but told me that they discussed needing to order "modules" so it is more than one bad one. She said I should plan on 6-8 weeks.

Mine had the yellow electrical error come up last week. No issues driving the car - all appeared well. Went to Porsche today. Has a single cell fault reporting aging apparently. Cell 19. Needs to be replaced.

I have been quoted 2 weeks. It is a 30 hour repair . Presumably at a cost to someone of £7-10k.

My car is 3.5 years old. I have an extended warranty and also the roadside assist. (I know the battery is 8 years warranty). Having driven in, they have sorted me an e Macan this afternoon as the car is deemed undriveable. Not sure if they would have done this if I hadn’t had the roadside assist. It is OK and will be fine for a couple of weeks although it is clearly a base model. But as always, they were very helpful in Tewkesbury.

2mo 17d. She's home again.
2 modules and some bus bars.
I will lose my mind if the error comes back at this point

I empathize. It’s a serious disruption to be without the car for long periods of time over these issues.

My tolerance for driving loaners I don’t like is low.

Intresting that they already started calling it aging
If you were out of the initial 8 year warranty, that would have ment you paying out of pocket - even though this is not aging, but manufacturing defect

Warranties only cover failures due to manufacturing or design defects, typically never aging or wear. After warranty neither are covered.

All parts have an MTBF curve, typically a normal distribution (a.k.a. bell curve). Warranties for expensive parts typically cover the early part of that curve, so most people can expect their parts to live beyond warranty coverage. Hypothetical example, say the failure curve for the whole battery is a perfectly normal distribution and warranty covers -1 sigma (16% of batteries fail during the 8 year warranty), then 84% batteries last more than 8 years, but only 2.5% last more than 16 years.

Problem is that 99% of these “aging” defect are actually manufacturing defects; which should have been fixed via hardware replacement as soon as the defects where known and the recalls made public.

Instead, porsche choose to develop a software that calls it “aging”, which coincidently is the exact language to make these manufacturing defects not covered by the extended warranty anymore, even if you choose to extend warranty beyond those initial 8 years.

It’s just that for now, no car is beyond those initial 8 years. But the fact that they are already calling it aging in services, and not just the software, is quite a clear tell.

It has been hypothesized several times on the forum that this is porsche clearly avoiding responsibility and passing down costs for manufacturing defects to the costumers.

Spot on.
It's the sort of practice you expect from some backstreet 2nd hand car dealer.

IMO Porsche seem to be in a race to the bottom with how badly they can treat Taycan customers.

Calling battery manufacturing defects 'ageing' to avoid future expensive warranty claims is a new low.

Straight to red on start up for me each time. The first time I had it towed in. That took 2.5hrs, and by the time the tow truck arrived the error was gone. Dealer didn't see any issues. A week or so later it came back. A Left it for 35 minutes and it cleared itself and I drove home. It started to become more frequent, and after a few weeks it finally appeared and didn't clear for two days straight. Towed it to the dealer and that started the first module swaps. Similar story the second time, but shorter overall timeframe. Error appeared, cleared 15min later. Dealer cleared the history or something like that. A week later it came back. Then disappeared. At that point I had the next service on the books. Had it a time or two in-between while waiting to take it in. They found issues with balancing that necessitated the additional two modules to be changed.
Long story short, never saw a yellow warning. It went straight to red. And it was always at start up. I'm guessing it does some sort of balancing / diagnostics while stored for some amount of time and that might trigger seeing it. No idea why it was clearing after that on/off/on cycling though.

My car is now in the shop for pretty much the same thing: RED "electrical system error" / always at start / sometimes clearing quickly, sometimes not / always returning. We will see what the dealer says (but they are backlogged...)

I'm sorry to hear that . See if they can at least get the tests run (of they haven't already) to determine the parts to order. That took a while for me. Hoping they get you taken care of quickly.
