981vc

Hi all!

I'm in the market for a Cayenne Diesel. Besides the extended warranty coverage for the diesel components, what other aspects (specific repair jobs, lookout for rust areas, potential for failure) should I be on the lookout for?

I'm coming from a 981 Cayman and have previously driven my friends 6MT 958 Cayenne so somewhat familiar with the platform.

Thanks!

I would get the newest CD you can afford with the least amount of miles you can afford. Depending on the in-service date some still have a good amount of bumper to bumper warranty left. The 2012s are almost out of the 10 year emissions warranty (which covers a lot).

The timing chain covers will leak (covered under the diesel warranty). There is a coolant leak that occurs under the manifold (sometimes covered under warranty). Other than that, the drive train is pretty bullet proof (other than the emissions crap, which is covered if under the 10 year).

There can be some electrical gremlins, but those are not specific to the diesels.

In short, I've had two of them, when my 2013 got totaled last years, I was not considering anything else, and got a 2016.

Finding a diesel right now, may be your problem. They are trading quickly and for silly money.

Watch out for signs of timing chain / tensioner failure. Very common on Audi 3.0 Diesel engines

@Whitegalaxie Please elaborate...what are the signs? I've got a Q7 TDi with 150K miles on it...

Here is good place to start when you land on one, gives you some important dates as well as if all the diesel campaigns have been completed: https://www.porschediesellookup.com/...ReadForm&c=usa

I guess it's the usual cold start chain rattle, common on both Audi diesel and gasoline engines. If you start getting "CAM shaft bank1 timing correlation" fault codes it's serious.. lots of threads over at audizine etc.

Whitegalaxie

Exactly. There are many more of these engines in Europe and Camshaft correlation fault and rattle on startup are the first signs. Engine out repair as the timing chains are at the rear of the engine.

IMO, most important factor is the "In Service Date" because that is when the clock starts on the warranties. Just because the MY is 2016, doesn't mean the ISD was in 2016. Mine is a 2016 and the ISD is 12/2017.

There is a guy who lives in my neighborhood with 200k on his. There are many who are negative about the CD. Drive a base Cayenne and then drive the CD. And then you have the benefits of only having to stop once every 600 miles plus when on a trip. If you want a "no problem car," buy a Toyota or Lexus.

I have a 2015 CD , our second one the first a 2014 was traded after 110,000 trouble free miles. The ‘15 has 85’000 on it and the only issue is a random failure of the cruise control which is corrected by turning the engine off and back on …. A software glitch other than that no issues great ride outstanding mileage and no plans to trade it. Regular maintenance however I did flush the fluids in the transmission and transfer case ahead of schedule , just because

Wonder if my Fidelity extended warranty will cover it. Probably not, as wear items aren't covered, and a worn timing chain isn't a failure, yet.

Thank you!

We have 2 2016 Diesels and they have both been very reliable. No issues whatsoever. You'll save a ton on service if you diy your own oil change (dealer charges around $750 for oil service in my area).

Newegg

2015 90,000. No issues at all. Well I guess they did replace the turbo last moth under warrantee. That is not very common.

Timing chain cover leaks are a thing on the 2013 and 2014. Mine is dry as a bone underneath.

I plan on keeping it a long time. I no longer have a DPF, EGR or DEF system……Malone took care of that.

Runs like the wind…

I knew someone that smoked 2 packs a day for 50 years and is still alive. It happens but not very often.
