I had it a couple times in the past, no idea why, but I used my Cobb tuner to reset it.

Yellow warnings mean safe to drive but need to look into it. Red warnings mean do not drive

I had this fault show up while trying to teach my son to drive it (6 speed manual). He was over-revving a bit and having trouble engaging the clutch and was stalling it.

Once the fault showed up. I took over and drove us home. I noticed no difference in how it drove, no smell of burning clutch, nothing at all. I was able to clear it with my Durametric and it hasn't come back.

Something as simple as the gas cap not being tight enough after fill up can cause this generic warning. The only way to know for sure exactly what caused it is the read the code with a diagnostic tool

Is that the only warning or are you getting others as well. If you have others, it could be a faulty coil. When that happens, you get Auto Start/Stop fail as well as PSM fault and the engine runs like crap.

You can take it to your local auto parts store and they will usually scan the codes for free. If you get the codes, we can maybe provide more info.

It is a catch-all warning for a myriad of things. Drive cautiously if yellow. If it goes away after driving just mention it at the next service. If it persists, take it in so they can read the deeper codes.

Happened to mine and it turned out to be a total failure (factory called it a premature failure of a critical internal component) of the PDK (at about 45k miles). With my PCA discount, it ended up only costing $13,000 to have fixed. Good luck.

So a PDK failure only gave you a single yellow check engine light – warning indicating that it was still safe to drive the car? Seems a little odd if so

Yep. Very odd. In a nutshell:
  • Made a quick local visit trip, 20 min each way. On the way home got the ECU error and "possible to drive on" message.
  • Next morning drove around the neighborhood to check it out and everything was fine.
  • Next day went on errand. Error message came on again. On leaving, it wouldn't go into reverse. Luckily I was on a slope so backed up but it would only go into 1st. Called my indy (a Porsche Certified mechanic I've used for almost 20 years). He said bring it in. Drove on side roads at near redline.
  • He kept it almost a week, and said he and no one he knows has any idea what it is. So flatbedded to the dealer.
  • A week later they called and said I needed a new PDK (which aren't built as replacement parts) so they would get it remanufactured. I suspect they shipped it to Germany for the rebuild because it took a month. Porsche America and the dealer would do nothing to help with cost (I did get a PCA member discount), even though the car only had about 45k miles because it was just out of the warranty period.
  • I sold the car as quickly as I could with a replacement PDK.
I've had Porsches for over 40 years. This was the last.

Interesting. There is a sticky thread at the top of the Rennlist forum from a guy that was in a similar situation and he tore the tranny down and repaired it. Bottom line is the fact that Porsche claims that the simplest of things on the PDK is unrepairable and must be replaced is nonsense. They will make that claim for something as simple as a bad solenoid or small leak from a gasket that can easily be replaced.

There is another guy that was also told he needed a replacement and it was just a nasty electrical plug connection to something that he repaired himself. Its an interesting read over there and his post and pictures at least start to tear down the walls that Porsche has had around this claimed mysterious, magical unfixable item.

Interesting to see the Rennlist article. I'm going to forward the link to all the shops around the country - some claim to be Porsche transmission specialists, to see what they say. Most all the guys I talked to said the biggest problem was that Porsche would not sell parts. A432 at Rennlist somehow found parts. I'm even more dissapointed in Porsche, the dealer and factory, and all the "specialist" guys. Looks like I could have saved $$$$. Last August when I had the issue, the first place I looked was Rennlist, having been a paid member for years.
