Project Purple - MY2026 Taycan CT4

No it happens during driving.

Seems like it's related to RAS:

I meant usage and how many miles on the clock?
So if there is an issue it won't happen at 10k miles, or would happen earlier like 3k miles.

Or it's just wishful thinking

I am not sure mileage has smth to do with it, but seems like something being faulty from factory.

If there's anyone here getting wisdom out of error-codes it's you, eh?

Well the suspension controller does not show anything at all apart from function restriction.
Also when this happens the suspension does not become stiff or stop adapting.

From what I'm seeing it's a RAS issue, which would also explain the strange things i've been feeling from the rear that I put down to tyres. I think it's not tyres but rather the RAS being defect.

Nothing you need on the first 200 km.
I'd love to see your car in the flesh.
It's a truely stunning colour nowhere near any Taycan I've seen before.

 

[RodeoDrive]

Hope that issue gets sorted for you easily - sure is annoying. At least there's the warranty and peace of mind, but still..

Just realized I drove 'your' car as a demo in summer. Cool color CT4, didn't have the nice gizmos you got e.g. PAR, though.

Offroad package and different wheels + spacers add so much IMO.
Maybe it's just me, but those are the least favorite wheels for me on the CT. I even like my winter Tequipment ones better than the 20" CT wheels.

Without the offroad package I prefer the ST looks wise. Or maybe like what @ze_shark did and paint the wheel arches body color.

Wasn't there another guy on the forum with similar/the same problem?

Might be worth while to find the details for the warranty, since it took forever for them to figure it out for the other guy from what i remember.

 

[RodeoDrive]

It is all a matter of taste, of course, but I do agree on the wheels.

For me if was this TG review that still makes me click, design wize:

- Cross Turismo design wheels
- gloss black wheel arches
- offroad design, yes
- loved the blue but was just too hard to get as a CPO so went with a crayon; had an Atacama yellow Z4 before child seats became a thing so I said this time let's go more understated

Spacers - interesting - what's the good and the bad about them?

I think he had active ride problems. For me there are no errors in the suspension controller but a fault in the RAS. I think we have a different problem.

It just looks less ugly with the 20" wheels. With the 21" you don't really need them.

See here, before and after (different wheels, but same size):

You can see how much more inside the front wheel is in the first photo. Looks ugly IMO.
On 21" you have the tyre 20mm wider and the wheel 12.7mm wider, and the offset is increased by half, so it looks good already, like you would have 7-10mm spacers built in when compared to the 20".

I love them, don't ask me why ;-)
For me it suits perfectly the "offroad" look of the CT.
For sure, I would not put them on a ST

You don't need a reason to love them just as I don't need a reason to dislike them. Porsche's have tons of customization options exactly for that reason. Something like design of the wheels is purely your preference, that's why there are plenty to choose from

Car going to dealer tomorrow. Have to take the spacers off though before that.

Dealer performed the whole active ride commissioning process, said they can't really do much else. If it pops up again they will have to make a ticket with the mothership and see.

My loaner was a J1.1 GTS on 21" Spyders, and man what a drastic difference in suspension quality. The CT with PAR is like floating on a cloud and glides over bumps seamlessly while the GTS throws it's nose up at every speed bump. When pushing it in the corners the PAR car manages to stay more neutral. Grip was better on the CT as well, but it's probably down to the tyres.

Its a RWS or PAR error?
