Audi entushiast buying first Porsche Taycan Turbo - used and need advice/help

[OakGreen]

Dear Taycan forum members.

I own an Audi S6 Avant and Audi R8 V10. But nevertheless from the first time I saw a Porsche Taycan I had an eye on it.
Now when the market is depreciating maybe the right time to grab one of the used one.
I was looking at one used Porsche Taycan Cross Turismo Turbo at my local Porsche dealer. The car is 01/2022, with 35.000 km.

The car is very similar to one of the press cars at the unveil (Neptun blue, with a kind of blue leather-less interior). It is equipped with Porsche Surface Coated Brakes (PSCB).
Because I am not familiar with those types of brakes (on S6 are just steel discs, and on the R8 carbon-ceramic), and because of that I would like to ask you if those brake discs on that particular car are worn out and will soon need the replacement? And also the pads?
Pictures attached.

Thank you all in advance for your help. I wish you all a safe drive.

PSCBs are theoretically a "lifetime" part. It should have the long term wear characteristics of ceramic brakes but at about 40% the cost of ceramics, so approximately 80,000-100,000 miles.

That said, there has been reports of cars that were tracked on PSCBs which has excessive wear on the rotors. Once the coating is below a certain measure, it needs replaced. Visually you cannot gauge wear, I'm not aware of any wear indicators on the rotors. Best manner would be to have a Porsche dealer advise on the approximate wear.

PSCBs rotors are a lifetime part and the difference from Steel rotors is that the Steel rotor is coated with tungsten carbide resulting in no brake dust, longer lasting pad life, but technically no significant superiority over steel kind in performance. As, an example my PSCB rotors are in perfect condition on a 50k Cayenne Turbo. However, since the brakes are used very rarely and lightly on Taycans, we have seen what you are showing in your pictures which looks like the coating has chipped and should be a warranty issue for replacement. Taycan maintenance schedule only calls for brake pads to be replaced at a 6-year mark due to age (mileage does not matter) but no mention of replacing rotors. My guess is that Porsche never tested these brakes in Taycan like application since it takes 4 years of hardly using them to see the chipping to occur.

Therefore, I would not buy this used Taycan without having your rotors replaced.

Dear,

thank you very much for your prompt response, and your insight.

I would like to ask if someone here managed to replace the rotors in particular state under warranty? Or the Porsche didn’t want to replace them?

is there any other thing/part that I should be particularly concerned about?

Nevertheless the car is still under warranty.
Again thank you and best regards.

You need to inspect the underside of the car, more specific the battery protection plate. If there is a dent in it (more than 3mm deep), Porsche will refuse warranty until the battery is replaced. You'll find a case here on the forum.

You can ask about a warranty repair, but rotors traditionally have been a "wear" part not covered under warranty. The service advisor will need to get a special approval from management and Porsche and have it assessed as a manufacturing defect.
