Background
I bought a 2020 CPO last month with the CPO+1 warranty (https://rennlist.com/forums/cayenne-...nightmare.html)
Within a week of owning it, got it with a check engine light on the dash w/ no other errors. Bought a OBD scanner and it showed "P02990 Turbocharger / Super Charger 'A' " error.
Finally secured an appointment with loaner and had the car fixed after 16 days at the dealer.

The warranty paperwork they had me signed showed ~ $6.5k worth of repair including labor. (see attached).

Question for the experience Cayenne Owners: How often does this coolant / water pump failure with coolant into vacuum system issue occur through the lifetime of a 9Y0 cayenne? I have no idea if the previous owner experienced this or not through the first 71k miles as I got the car at 71k. How soon should I expect to see the problem again? Trying to assess whether I should unload this car as soon as it approaches my 3yr CPO+1 warranty expiration date in 2027. Really don't to shell out $65k for this down the line.
Any input is greatly appreciated. Thank you!

 

Wow.. my 2019 Cayenne S with 103,500 miles, which I paid $120K for it, is only worth $35K now..

Last Porsche for me..

There are many other options now that make more business, performance, and pleasure sense....

I am beginning to believe what several people have mentioned, which is Porsche knows that their business profits will be severely impacted over the next years, and Porsche is making sure they will maintain profits for many years with ultra-expensive repairs, labor, and parts costs..

All people buying recent Porsche vehicles with expensive proprietary designed parts and with flawed designed parts that produce serious collateral damage when they fail, will have their vehicles become worthless as soon as they lose their warranties..

Like some Mercedes models(W163/MLs), at one point in time, these Porsche vehicles will be driven exclusively by mechanics who will be the only ones who can repair them cheap enough to keep and own them.

 

I apologize, i meant to type $6.5k, not $65k. Nevertheless, still super expensive

 

Man, I thought it was a total engine meltdown.. Still, I stand for some of my comments, since the repair for these broken water pumps can run $10,000+ if the water enters the engine components through the designed association of the vacuum system..

 

Which model or brand has the loss less ?

After the warranty , you can have the Porsche repaired in any workshop for significantly less cost

 

Sorry to hear.

These water pumps are garbage.

Should cost $4k at an Indy and ~$2.5k and a weekend of time DIY.

Car in the OP is a MY20 .1 S with 71k miles.

 

Thanks. If this occurred after CPO warranty, I’ll definitely look into the Indy route.
Have you had yours replaced yet? If yes, how many times to date?

 

It will only be less for labor and if you have a competent Porsche mechanic in your area.

For other luxury brands, going to the dealer is not a ripoff and the normal and recommended way to go..

 

I was mistaken, I just saw the latest current value of my 2019 Cayenne S with 103,500 miles vehicle, and it is not $35,000 but only $31,000..

Pretty steep discount for a $120,000 vehicle bought new, in excellent condition, and with so many options in it..

 

No pump replacement yet. I have ~2 years of CPO warranty remaining. Unlikely I will not achieve the 100k mile mark in the next 2 years.

When CPO is almost done I will decide whether to preemptively replace the pump or to dump it and move on.

 

PCSS does not specify fascia or bumper removal for V6 water pump replacement. Neither does it specify cooling pack (radiator, condenser) loosening.

Big(ish) jobs to access the V6 water pump are belt removal (not that big of a job), intake pipes removal and coolant crossover pipe removal.

 

Major parts prices from Porsche Atlanta Perimeter, whom I have found to be one of the more competitive dealers selling parts online.

Part numbers are from the invoice posted above. I did not include screws or seals, assume $200 in total for these.

$266 water pump
$255 thermostat
$93 coolant valve
$85 coolant pipe
$467 vacuum line --> this is a complex system of vacuum tubes
$60 vacuum reservoir
$527 vacuum pump
$372 control box --> this is a turbo wastegate acutator. Why was this replaced?
$82 vacuum line
$200 screws and seals

$2400 total parts purchased retail. Allow for 10% contingency so a DIY project <$3000 with a weekend of time is the lower estimate for this job.

Deduct $1000 for vacuum pump and lines if the water pump is replaced proactively before it fails and takes the vacuum pump with it.

 

^^^ Nice work pricing out the invoice @chassis .

But, hey; next time we can all save chassis time and trouble pricing out warranty invoices. Your dealer has two invoices. The one you sign and the “copy” that they give you — they are two different documents.

The one you sign has all the prices listed. They use this to bill Porsche (or the aftermarket warranty company). The copy you receive has a column full of N/C’s.

Ask for a copy of the invoice with the prices. Posting that copy will be more useful to the forum.

Nevertheless, thanks to c-dubmobile for posting the invoice. Very helpful even without prices!😀

 

Just took my 2020 CPO base in for annual service. I don't know why I do this but I change my oil at half cycles but take it at the service interval for them to give it a once over. Well, I'm glad I did.

69kmi and the water pump is leaking. Thankfully under warranty but "excited" to see how much this repair would have been out of pocket.

I asked the advisor, is this normal or abnormal. "Normal, about this mileage". Good god. I would hope that Porsche would fix the design. 70k miles is too soon for a part like the water pump to fail.

 

hopefully we won’t see this prob for another 70k miles, long after the CPO warranty 🙏
