They can choose to do so, but it's not required. The reason they do them together is because the PSCB have an "expiry date" - I believe it was 6 years? Or might have been 4?
And since normally the Taycan barely uses the brakes, then they do both the pads and the discs when the time runs out.

Either way PSCB is a disaster. Go steel or PCCB IMO.
pads not rotors - rotors do not age “out”

I had them on my 2021 base, I wasn’t thrilled to see them on this car TBH.
I recall a few scary braking incidents on the 21, and in general the exorbitant cost of the consumables is not great.

I liked the steel brakes on the 23 just fine.

Is it possible to just “downgrade” to steel brakes once this new set of PSCBs is done for?
Any coding changes needed?

no code changes required for brakes

You don't need to code anything for sure. I don't know if it's possible to downgrade to steel.
As I said, I have a few part numbers with the correct diameter and thickness, that match the PSCB on the Taycan, they are Panamera discs.
But I don't know if the offset is right and whether the hub is the same.

Need to get them side by side then I will have an answer. Right now there is no aftermarket option for steel brakes apart from also changing the calipers, which is very costly. And then warranty is dodgy - if you just fit discs from a panamera plug and play, then that sounds a lot better to me than messing around with the calipers.

To be honest I don't expect you to have issues with the PSCB unless you track the car.

I thought I read somewhere that both the pads and the rotors have to be replaced at 6 years, but I am not completely sure.

certainly not PCCB rotors every 6 years ($35k service every 6 years even porsche is not that bold) - 6 years is shelf life for some pad material and given usage and exposure to the elements new pads every 6 years is plausible - i’d reject the rotor swap if i’m only doing pads due to age and not wear

i highly doubt PCSB need replacing due to age but maybe - normal steel and PCCB do NOT need to be replaced due to age - anyone telling you different is simply running g up the bill

PCCB are considered lifetime for the car. I agree with you also that rotors don't have a shelf life.
PSCB are just a Frankenstein, maybe you have a benefit of them on an ICE car where they reduce brake dust, but on the Taycan where 99% of the normal braking is done by recuperation the brake dust argument is out the window.

No, the pads needs to be replaced every 6years, mandatory, no matter of use - for them to be allowed to "warranty" your car.
The PCSB discs do not - I have confirmed it at 2 dealers in switzerland.

Fair enough, in that case that dealer is just scamming clients when they do both.

I agree with that, and find it strange that PSCBs are a required option when you get the Mission E wheels.

I had no issues with the steel brakes on the 23, and while my wheels were black so they didn’t show much dust regardless, I really didn’t feel like I was wearing them as I did on a 911.

Interesting that PCNA recommend tyre rotation? That can not be correct? Haven’t all Taycans got a staggered wheel setup?
Secondly checking the spare tyre? Has anybody got such a thing?

yeah this is directly from PCNA - the same group that had the Taycan listed as a 9.6 kW L2 EV for 3+ years…

At least they didn't recommend checking the exhaust for leaks.

Maybe by "Tire rotation and tread inspection" they mean "once lifted off the ground, rotate the tire while inspecting the tread"? It is recommended every year, while they only recommend actually removing the wheels every 4 years to inspect the brakes. ;)
