Update- Transmission is toast. Requires new PDK. PCNA offered no good will. I will update thread when all is set and done.

Ugh... That's not the news any of us want to get. Do keep us all posted. So sorry to hear this!

Damn

I assume you have fidelity platinum? or the basic

Update till I get additional details from my SA - In my situation the Fidelity Powertrain warranty is covering PDK replacement. Hopefully this eases some people’s concerns who have the same warranty.

I bet you are relieved.

Great. Glad to hear it. What exactly was the cause? Distance sensor failure or TCU failure?

Not to be negative but I'm going to bet the transmission is fine and you have a wiring or TCU issue. They replaced that transmission 30k ago and now they are going to do it again because it's not their money (and in this case luckily it isn't yours either) but I bet you'll have to go back after this happens again.

Had to go into the transmission option to see the actual codes which were P1734, P1736 and P1738.

LOL. I hope it doesn’t have to go back for a 3rd time but who knows.

how come lightening strikes 2 times same place ? Is this a lemon, incorrect driving habits or what ?

OP what year is your 991 ?

Yeah, I would agree with above: probably simple problem: sensor needs replacing for $100, but what respectable Porsche dealership wants to replace a $100 sensor, when they can replace a $15k PDK?

Yes,

The same company that requires you to replace a windshield because of a faulty rubber gasket would definitely favor replacement a transmission over a sensor.

It’s a 2013. Your guess is as good as mine but from what I’m aware of the car hasn’t been abused.

Just a thought ….but maybe use a Durametric or Cobb Accessport to monitor your PDK oil temps. If PDK is running hot, then maybe it damaged your distance sensor both times. PDK has a gear oil cooler that works with a COV. Might be worth money to replace gear oil cooler with replacement PDK. Two bad PDK’s in same car in 30k miles each is so statistically rare that it should be connected or related. Probably same issue caused both failures as others have suggested. I do not believe in coincidence. See RelatedThread where similar problem ended up being a pinched wire causing voltage problems with PDK/controller not discovered until third alleged PDK failure in same car. Just my 2 cents. Best wishes and glad to hear warranty covering it.

Solid idea. Same failure is extremely unlikely. Maybe car has some frame damage and there is a twist that is resulting in an actual PDK failure.
