4yr service inspection & information about PSCB

[M_Taycan_Turbo]

Today my Taycan Turbo MY2021 had its 4 year service inspection.
MJ2021 / 40.000km on the clock
As the break fluid exchange was already done during the break recall two month ago, the service costs were reasonable.

South Germany - PZ Ulm
Total gross costs: 650,- €

Coming to the downside! I was shown pictures of the break discs and was told that the discs are heavily worn. All discs are showing spots. They don’t see a reason to exchange the discs now but I was highly recommend to exchange the discs at the latest during the scheduled brake pad exchange in two years (6 year service inspection).
As I know the issue with this particular break (PSCB) in general, I just asked why he obviously wants to make his problem to my problem, as this brake obviously has a major flaw, not only on tycan (I also known that the Porsche Approved insurance is not considering to cover any costs in regards to that). So I asked what he can offer me. Of course he had no answer to this question and replied that he also thinks this break should not be ordered or even sold by Porsche.

Overall my car has no flaws so far an I love to drive it! I just renewed the Porsche approved for two more years and planned to keep it as I don‘t want do go back to ice, but the break topic now gets me thinking. Charging around 15k EUR for break discs at 60k km, on a car which in 95% uses the regen for breaking is an absolute joke! Considering that I never pushed the break hard, nor has this car ever seen a track makes it even a higher joke.

I just checked the spare part prices online for the original PSCB break. 4 Break discs (front and rear axle) total gross costs ~3.800 €. Reasonable compare to the costs at the Porsche dealer but of course still expensive compared to the steel discs.
I haven’t found pads for the PSCB. Could someone share the part number please?

whats is your take on that? Anyone else with the same issue at the moment?

This is some great Intel as many of us will be facing something similar.

My expectation was that discs will last well into 100k miles or even forever because the pads are only replaced at 6 years due to age and not wear. The pads usually wear first but certainly not carbide coated discs. I would like to see if any other owners experience carbide disc wear which is actually carbide coat chipping.

My only other comparison point is PSCBs on our 5 year old and 50k miles 2020 Cayenne Turbo with discs looking flawless to me, but I will get the pad measurement and disc inspection this week at 50k service and share the outcome. May be the chipping occurs to rare use since the wear pattern on the Taycan is not mirror like all over like on the Cayenne.

That sounds like bullshit to me.

My car has almos twice your km, and1 extra year of life; and porsche has never said anything about the discs. And I brought up the discussion myself, having had some squeaking / squealing problems.

I also think in some places they are subject to warranty of 6 years or 72.000 miles; whichever comes first.

They are basically telling you to replace them as soon as they are out of warranty. Kind of bullshit

I had my Cayenne Turbo PSCBs checked today and they looked flawless at 5 years and 50k miles. I think any chipping of the carbide coat on the Taycans should be handled under warranty or good will. I would not pay for rotor replacements if they start chipping as it is a manufacturing defect and clearly not a wear item. My other takeaway from your experience is that if PSCBs are prone to chipping from little use, we all need to be making as much use of them as possible by hard stopping when regen is disabled (morning drive after a period of non use). The only thing that is replaced per manual is pads at 6 years, to say it again, for age reasons and not for wear.

Glad to hear that your Cayenne Turbos PSCBs looked flawless!
I agree that the Taycan PSCB issue should be handled by Porsche under warranty. Unfortunately Porsche has another opinion. At least that’s what my local Porsche dealer says.
I agree to everything you said. I am not planning to change the rotors but if at one point the chipping gets worse, the side effects will also get worse and the only way to get rid of it is to exchange the rotors. Only time will tell in my case.
Absolutely ridiculous to think about exchanging the rotors on a car which uses the rotors only 10%. If you do the math, in my case after 6 years and 60k km, the car used the rotors around 6k km, 54k km done by regen. And the rotors of your cayenne, which is more or less the same weight used the rotors 100% and breaks are flawless.

You know what, I do not mind asking my dealer what they would do if I told them my Taycan PSCBs are chipping. Would you please share pictures as I am sure everyone here would benefit from seeing what's going on. I have incredible relationship with my dealer as they go above and beyond for me every time. I sense your dealer might not be credible so I would call Porsche corporate office and ask them about it as this cannot be an isolated issue and chances are there is a TSB on that with info on how to handle it. I know there is a TSB on the PSCBs on squeaking and my dealer handled it under the TSB although it is not completely gone but below the dB threshold for further work.

As the major spots are on the inside of the rotors, I will ask my dealer to provide me all the pictures they took during the service/inspection last Monday. In addition I will take some additional shots from the front of the rotors. I will post all the pictures tomorrow. Feel free to show them to your dealer. I am curious about your dealers opinion.
I appreciate your support!

Some first pictures of one rotor from the front side. As side, I will upload more tomorrow.

The pictures will help a lot. This looks major with coating clearly chipped. I looked at mine and while Cayenne's look like a mirror, Taycan's look similar with grey belt and spyder web looking squares but not chipped. I suspect the squares get worse and then chip along those lines. I will ask the dealer if these spyder lines even supposed to be there.

I assume any warranty will not cover this because this is a wear and tear item and not a manufacturing defect. I would have to believe someone else on the forum had to deal with this.

 

[M_Taycan_Turbo]

Correct! This is not under warranty or covered by Porsche Approved. See also workshop manual attached.

 

[SergeyIndy]

I think that is your answer then and the answer for everyone, as my dealer would most likely follow the same procedure and deny any kind of replacement under factory warranty. I have the same square patterns so in time the coating will chip away along those pattern lines as you are showing. The next best thing is to ask for replacement under good will. I have done it for other vehicles when I was out of warranty and had a high cost component fail. There is a form that the dealer would complete and submit and it may be approved or denied. Mine were always approved. They typically approved one major and one minor per vehicle.

That is exactly the way I am aiming for. I was already in touch with the sales guy who sold the car to me back then. I had a first phone call with him (this dealer is 200km away from my hometown) and shared pictures and details with him. He will go back to his service department and will most likely come back to me with no good news, but as you said I will then aim for replacement under good will so that he shall fill out the form and send it to the Porsche headquarters. That’s all I can do for now. If it gets declined, I will just drive it and will find out what happens. I don’t have any safety concerns so far.

I agree with your plan. This is what I would do. I will speak to my dealer about it as I promised as report if they recommend handling it any differently.
