Thru Fidelity it will extend from the warranty contract date. I was just quoted a Premium Care policy from them for about $4525 4/48k.

Raises hand as another failed (previous) PDK owner, the car was within its factory warranty when it occurred. The car was a 2013 Carrera S with 13k miles, no advanced warning, stopped for a coffee, got back in the car, no go. The bill to the dealership was around $11k. My dealership was easy to work with, but disclosing the problem when selling the car wasn’t a helper.

Happy to to hear things worked out for you.

Last month, my car was driving fine. No issues. When all of a sudden, I got a PDK failure warning light on my dash. No reverse. And only 2, 4, & 6 gears were available.

I happened to be near Porsche Irvine, CA when it happened, so I pulled in.

A Porsche Tech was hanging out and noticed my car. I showed him the issue and without blinking and eye said the PDK Transmission will need to be replaced.

The cost? About $20,000 to $25,000. And, this was just the beginning.

My car had just passed the 50,000 mile mark, so I was out of warranty.

If you have this error, ensure your dealer verifies the following before replacing the entire transmission.

01 Loose CV Joint(s)
02 Verify the Battery is Not Bad
03 Verify the Change Over Valve (COV) for the Transmission Fluid Cooling
04 Recalibrate the PDK System
05 Replace the PDK Control Unit & Recalibrate the System
06 Dirty or Low Transmission Fluid/Oil
07 Replace the Valve Body

Now let me set your expectations. None of this will work.

You’re most-likely going to need a full PDK Transmission replacement. And, if you did some of this work beforehand, the bill is much higher than $25,000. The Valve Body replacement is over $4,000 on its own.

HOW DID PORSCHE HANDLE MY ISSUE?

Here’s a little secret, the Porsche Service Advisor at the dealership holds all the keys. Don’t think they don’t. They make the call on who’s paying for it. Why? Because only the Porsche Service Advisor can request “goodwill” to PTECH and PCNA.

So, if you’re having a serious service issue – be very nice to your local Porsche Service Advisor at the dealership. I actually noticed a Porsche owner bringing my Service Advisor lunch!

FYI, calling PCNA and speaking to a Customer Service person does nothing.

I want to thank Victor Morillo-Delerme at Porsche Irvine for helping me through this. He fought for me and my outcome was acceptable.

Also, I must say that PCNA handled this right. They listened to my Service Advisor and took care of us. Staring down a $29,000+ service bill is not something you want to live through.

Of course, if I was under warranty – this would not be an issue.

I hope this story helps fellow Rennlisters and inspires you to at least buy a drivetrain warranty for your PDK cars.


My Details:

2014 991S PDK – $134,000 sticker. This was my fourth 911.
Never tracked. It’s a commuter car.
I used the “coasting feature” on my PDK every day. I’m no longer going to do that.
When the error happened, I had no warning. No noise. Nothing.
I feel Porsche has an issue with PDK.
I feel PCNA should put a separate warranty on PDK – maybe 5-years unlimited mileage?
This was my first PDK car.
It took Porsche Irvine about 2 days to replace the PDK transmission.
why do you think the coast feature had anything to do with the issue?

I'm not sure why an expensive PDK Transmission - where the first service is not until 120,000 miles - would suddenly and completely die.

My only thought is that using the coasting feature everyday might have something to do with it.

I may be wrong, but I'm quite taken-back that such a high-performance transmission - could just break with minor use.

The PDK "coasting feature" is actually really great. When not in Sport Mode - and in automatic mode - the transmission will enter neutral almost every time you let your foot off the gas pedal.

It may not seem like much, but when you're commuting on the 405 freeway everyday - I've been able to get over 30 mpg when in this mode.

But, I always wondered if it's safe for PDK....

Porsche Irvine is amazing. It's brand new. A sister dealership to Porsche Newport Beach.

They're service bays are awesome.

Glad it worked out for you....I had a 2012 997 GTS once and PDK developed a tiny small leak. I would never had noticed it but i was under the car cleaning the suspension, chassis and rear axels and notice a tiny oil stain. Took it to the dealer and a seal from PDK to rear housing was leaking a tiny bit. You can’t replace the gasket seal..Porsche makes you replace the whole PDK transmission!!! Dealer gave me a rash of crap because I tracked the car but after arguing for a few days PCNA did it all under warranty.

Well, sounds like I need to start saving for that Fidelity Platinum warranty I was quoted a while back.

This exact thing just happened to me about a month ago on my 2018 c2. Dealer replaced the valve body and so far no more issues. Based on what I’ve read it sounds like it’s going to happen again, just a matter of when.

without actually doing the search, does anyone know if this pdk issue is across the Porsche line? Are Macans, Panameras, Cayman's, etc all having sporadic failures?

I was just quoted $4525 4yrs/48k miles. What were you quoted? Thinking of shopping the dealers too. My factory warranty is good till 8/2019.

Same thing here. Just it back from my PDK replacement. I had CPO coverage. The service advisor told me that my out of pocket would have been $22,000 otherwise.

33k on the odometer.
