PDK warning message

It's quite interesting that starting 2017, I am seeing more and more PDK issues reported ALL OVER. It sure looks like PDK lifespan is around 7-8yrs or so. Not a great sign! I wonder if PDK was updated in 991 or 991.2, and specially for GT-cars, and if those have less issues or not (won't know for a few years)?!
Generally it looks like the MORE we put electronics into our cars, the lesser the reliability and lifespan, I think 997 would be on of the last Porsches that could last for decades and mended easily, possibly 991... BUT any of the newer cars are so dependent on their electronics, they will be incredibly prone to issue moving forward, specially if Software updates are not provided for cars beyond a certain time.

I also think.. An interesting point and I'd love to hear too..
I know too many people that their PDK has failed. Around 80-100 km.
A lot of problems that start with "smoothing" or slow shifting of the gears.
The Solution: replacement of the PDK or, renovation (VERY expensive)
This is worrying because I also think of upgrading to PDK (or 997.2 / 991.1 manual) in the future [Today I'm with TIPTRONIC S 997 (only in manual mode and sports
).]
I know that the gt3 991 PDK is different. Hardware and software.

One major problem is that you can't service it, so the issue maybe a sensor inside PDK that cannot be changed without taking the whole thing apart, resulting in tens of thousands of repair... again points to my earlier point of added electronics making Porsche 911 not much of a long-term car, as it used to be from first gen till now!

LOL... really? Zero? Just look around this forum and 6speed to see dozens of reports. It was maybe close to zero in the first 5yrs of use, essentially when new, however, starting the 6th year they've begun to develop all sorts of issues or complete failure. Race-proven? If so, WHY not used in Cup cars?

I have seen no widespread reports. Keep in mind there were 97,082 first gen PDK equipped Porsches from 2009-2012 (North America Only). So even if you say there are "Dozens", that's still 0.0001%, or effectively "0"
The PDK is extremely robust and race proven. It was developed and raced in group B rally cars in the 1980's. The most reliable DCT to date. By a large margin. There are plenty of cup series and race series with PDK equipped Porsches.

It is not the same PDK transmission system. Similar technology.
And the majority with sequential transaxle.

PDKs are robust. Failures are almost non-existant. But, like anything mechanical.....things could break.

That's the irony here. The mechanical part of the PDK does seem robust. What seems less robust are the various electronic components that are part of the transmission. My failure and as far as I remember, every other failure I've read about here and elsewhere have been electronics related one way or the other.

AGAIN, then WHY it's NOT used in their Cup cars? Go drink your PDK coolaid, it's 100% clear that it's starting to have major failures and issues from 2016 onwards and its just gonna get worse! PDK may even be as robust as you claim but ONE failed temp sensor could render the whole transmission unusable... so there!

By the way, although the racing is not the same transmission system. Still, at the races the most important thing is to be fast, after that reliability. In contrast, in normal use, the reliability of the gear system is more important.

Your entire argument on PDK reliability is based on it's absence in Cup Cars? It's not in Cup Cars for servicing and gear change accessibility. Nothing to do with robustness or reliability. PDK IS in the Porsche 918, GT3, GT3 RS and GT2 RS... Cup cars have less power and EXTREMELY shorter service intervals than the aforementioned. Isn't it past your bedtime junior

That's my thought too. Especially as I turned off the engine, waited about one minute and then started it up again and then drove two miles to get back home. If the transmission was really running hot the message should have recurred but it did not.

I remember my dad and other old-timers back in the day yacking about their new Cadilac or whatever...... (hey! I am now their age... I guess.... ooof...)
When one showed off their fancy auto-tuning radio with seek, a very mechanical, motorized feature, or their auto-ride leveling system... you would hear the air pump run to fill some bag in the shocks.... the other would say something like: "What is that going to cost when it breaks?"
Hmmm......
