Broken clock can be right twice a day... They are right in this - temperature errors are secondary. And 0730 points to a failed speed sensor. By not gettin the right shaft speed values on two sides of a drivetrain - car thinks that ratio is wrong, throws 0730 and goes into limp mode to protect the PDK.
Those particular sensors are not available from Porsche, and dealers will not do the repairs. But we manufacture this sensor and we can recommend the PDK repair shops if you contact us directly.
Respect your opinion Vlad as I know you have done a lot of work on this. Completely agree the ratio fault would normally indicate a speed sensor failure (and I noted this above) but I cannot wrap my head around the three overtemp faults. Why would a speed senor failure cause this? That's why I was thinking a clutch failure. Perhaps the speed sensor is fine and there really is a speed mismatch from the clutch slipping. That would heat up the clutch fluid quickly.
Regardless, speed sensor, temp sensor, or clutch it's all fixable. And fixable at far less than the hit Larry would take selling it as a roller.
Yep any and all of those repairs would be FAR less than replacement. Waiting to hear back from Larry - would love to help him get back on the road and be happy with his whip. 50+ years of PCA is no small feat.

I agree that the temp and speed sensor faults are just symptoms of the actual issue. To me it looks like a problem with the clutch or the systems ability to control it. I had very similar symptoms and codes on a 987 which was corrected by replacing the valve body (my next step would have been to replace the clutch). I'd think it would be easy to confirm reasonable readings from both the temp and speed sensors using PIWIS to rule those out. Anyway, here's the troubleshooting diagram for the P0730 code.
I appreciate all the suggestions I have received from you all.
As I have said I’m getting too old to fight.
14 years of joy and all the extras I personally put into this car allow me to look back on it with joy.
But. For me, the time has passed.
of course I welcome any bids, however, I am no longer interested in repair.
thanks again.

It saddens me to read this, but in my many years of experience I understand when a phase in life comes to an end. Good luck as you move forward wherever your road leads you.

thanks for the message, I have appreciated all the interactions I’ve had over all these years and I will miss it!

Sorry to hear the news. The PDK does present some huge costly repairs as well as Bore Scoring but still the % is low.
I'm sorry you had to deal with this and hope you shop for a 997 soon!

The question to ask here is "did the overtemp errors happened at the same time as 0730?". On paper it all looks like it's a log of things happened at the same time, but in reality those errors in PIWIS can be half a year apart

Good point. As was noted above, using the PIWIS to read the real-time speed sensor and temp sensor data could probably sort this out pretty quickly. Dealers won't do it though despite the fact the capability is built right into the tools they have.
