Was told by a Porsche tech, PDK transmission is vin coded and can’t be reused in another vehicle!
The codes

That is a flat out lie, there is no other term for it.

Edit: Adding to this that the PDK as a unit is completely agnostic to the car it's in provided it's matched to the model (i.e. it's for a 997.2). So either your tech is lying to your face or he's full of it. Sounds harsh but these type of misstatements (that *always* seem to limit customer choices rather than broaden them) happen way too often.

Looks to me like the temp sensor you had replaced a while back failed again, or more likely the crimp job they did installing it failed. Either that or they misdiagnosed the problem the first time it happened and didn't fix the actual problem.

Adding here that the P730 ratio fault means the input and output speed sensors don't match. It's kind of an odd fault to see when coupled with the overtemp fault as it usually means a speed sensor failure. Hopefully it's just some sort of false fault that got triggered by the temp faults. Worst case scenario is that the clutch failed and is slipping (causing the P730 ratio fault) and all that slipping heated up the fluid to cause the overtemp faults.

Any signs of slipping before the fault was triggered?

No slippage, until the entire car was slowed to stop, then had limp, slippage till got up to speed. was asked that by the dealer techs!
this was after the trouble code came on!

Going back a ways ... There have been a bunch of PDK failures that ended up being bad coils. The 997.2 coils are pretty good but can fail, especially if the car experienced salted roadways. Arcing at the coils disrupts the sensitive ground in the car's electronics and can create sensor errors that get misdiagnosed by the computers.

A poor battery can also create chaos. Computers and sensors depend on good power supplies and that starts with the battery (and connections).

Good point. Have they tried just clearing the fault and seeing if the PDK returns to normal? It would likely fault again until the underlying problem is fixed but it would be helpful for diagnostic purposes.

I believe so!
I had mentioned the coils.

Seems like shops are getting more brazen with their dishonesty.

What is the availability and possibility of converting a PDK car to manual?

im thinking used trans, shifter, console, pedal cluster…..

what else? Some ECU for something transmission related?

Yes, and it's not just car shops as honesty is plummeting across institutions in recent years. I have to tell you I hate it as it concerns me about the world my kids will inherit.

Anyways, I think I was personally responsible for getting a thread deleted yesterday for mouthing off this subject (i.e. the importance of acknowledging truth) so I'll put a sock in it. Glad to know I'm not the only one seeing it though.

any suggestions as to what to do with the car??
So if I understand this right, your temperature sensor was replaced less than two years ago. Is the temperature sensor an internal or external component? I'm asking since as I've said many times I've had two distance sensors fail which both required full replacement of the PDK since I was told the distance sensor is an internal part and the dealers still aren't allowed to open the PDK's to replace any faulty parts. Both my replacement units came with a 2 year warranty.

So why aren't you getting any warranty coverage for your failed sensor?
