Wow - that explains exactly why I had a problem with my 12 Volt for the last two winters before having the 12 Volt switch update recently - great to know reason.

No, it was just you and your car. Most cars were fine.

Will be dropping my Taycan for 2 campaigns: WSS6 and ASB2.

The 60k+ number includes 3 models, so don’t be fooled by it.

How long does it take for these things to show here?

992s also ... eek, hope mine starts after the winter!

Does this imply that the 12v is common across various models, I guess so?

@W1NGE, welcome back to the club!

Mine is in for the European nav issue soon and they’re doing WSS6 as well, haven’t had 12v issues but glad it’s being done reading that!

Unlikely it will show on Porsche recall site since it is not a recall. Your dealer should be able to tell you if your VIN is included in the workshop campaign.

I just had these done along with ASA2. I dropped my car off late Friday afternoon and they had it ready Tuesday afternoon.

How do I tell if my 2022 needs this WSS6?

You can call a Porsche dealership and just ask the service dept to check for you on the phone, and then schedule it right then and there if it applies.

Yeah... looks like I just missed it when I brought mine in for the tire. I'm planning on having them look at some door rattles so maybe then.
