On-board charger replacement options @ yellow Electrical System Fault @ out of warranty?

[Murph7355]

....
If these Lithium ion batteries in the Taycan don’t last at least 10 years then the weight trade off was not worth it IMO when you factor in the 8X to 10X increase in parts/labor cost.

For who?

Porsche meet whatever their design objective is (won't have been the same as Boeing's), customer picks up the replacement cost, Porsche make a few $s more on the more expensive battery

Weight/energy density will have been the priority for Porsche. I have one on my Caterham 7. Weighs a third of a lead acid battery saving 3% of that car's total weight.

1. This is too much.

2. Porsche has extended the warranty on the OBC to 5 years, so probably you should not have paid anything. On your car it would be until 2026.

You need someone with PPN account to look up your car details via VIN.
If you have the 22kW charger then it should be covered since late April.

If you indeed have the coverage (which I suspect you do) I would ask for your money back, because it should have been covered under warranty.

I have the info from @ct14garage. I assume "Hochvolt Ladegerat" is the one? I already saw this but I assumed it was something else, not the OBC. This could be awesome news. I'll go to my dealer first thing on Monday..........

Yes as far as I know that is it, this was also confirmed by my dealer. So you should not have paid anything!

MY TURN!
This morning I woke up and noticed the car stopped charging at 74% instead of the usual 80 which is set and reached everyday.
Red light on the plug, so I disconnected but now I got the yellow electrical system fault and the car doen’t go into gear.
it so so frustrating non being able to drive to the dealer with a 74% charge…

some said disconnecting the battery could fix this? How do you do that and what risks are involved?

They're talking about the 12v battery.
You disconnect it same as any other car.
Pop the hood, have a look.

Wow… that’s a genius answer…

Disconnecting the 12v battery is a 1 in a million shot probably. Actually I don't think it's an actual option but I know the feeling of trying everything before accepting the situation. Check this video
It's not related to actually disconnecting the battery but it shows you how to get to the battery. If your 12v battery is not dead yet then ignore the jumpstart part and open the front trunk from your key (skip to 4:19 @ video). Once you reach the battery disconnect this cable:

Expect some sparks while you detach the cable (try to dettach it in 1 attempt, don't wiggle it). Leave it detached for, I don't know, 15min+ then reattach it.

WORD OF ADVICE: don't start and stop your car continuously while having the yellow electrical system error hoping "this time it will start" because during this problem the 12v battery is disconnected (or at least not being recharged) from the high voltage battery and it will deplete VERY FAST and you will end up with a completely dead car and have to jumpstart it as shown in the video to be able to turn on the car and put it on neutral to tow it. This happened to me and it was a pain in the ass

thank you so much! This is the kind of help which really brings value to this forum!
Thanks especially for the word of advice, this is something I was already doing…

also, looking at some older posts I was able to find this useful step by step description of how to disconnect the 12v battery side effects included:

UPDATE: I just got my money back ? thank you @prj for mentioning this!

I asked them why didn't they consider this warranty during the initial repair, they said the warranty info was not present then and was added only after the repair, on 29 April 2025 to be more specific. But they also didn't bother letting me know, I had to find this myself from here and ask them explicitly for my money back...

Great!
Yes my dealer said the same thing. They were advised that if the customer knows about it then refund, and if not then keep the money.

Pretty damn sleazy if you ask me.

The total cost to replace a single lamp every 3-6 months costs the city or town $5K to $10K per year per traffic light.
LED traffic lights cost less than $1000 but have zero labor costs for replacement and 90+ percent lower energy consumption.

Going by these numbers, why are traffic lights not coming as "doubles", two traffic lights in one? Imagine each traffic light actually has 2 traffic lights, 180 degrees offset only one of them active, with a motorized rotation mechanism which can rotate it 180 degrees when active light burns out. Heck, put 4 of them 90 degrees apart, that would quadruple the life of the LED traffic light at probably less than 4x the cost, yet still cheaper than a single one plus one replacement (which by your numbers is a minimum of $6K, $1K original light + $5K replacement cost + 1K replacement light).

Aka, they scam when they can, and if you tell them to stop scamming you, they stop.
Lovely premium brand, porsche

Not to mention how obvious the bullshit about not seeing the warranty is...
