Thanks. I'll stop trying

 

Can we do a PDK relearn with this device

 

Anyone peaked around to see if there's a way to set the default audio source at startup using ThinkDiag? Trying to avoid that FM blast while car waits to re-connect Bluetooth. Thanks!

 

This would be helpful. My car randomly turn on the radio once in a while even though I never have it on when shutting the car off.

 

That would be so good. When I still had the crappy XM trial the car would always start playing smooth jazz loudly. Now it’s blasting FM.
Sometimes you can change source to media or whatever, but a few starts later- blasting FM again.

Hell, I’d be happy to delete sources entirely from the PCM.

 

Don't know about Thinkdiag, but remember this from years ago. Reviews are mixed, some say it works, others say somebody is having a great big laugh.

 

Interesting seeing this issue with coding a .2 compared to a .1. I definitely want to do the temp gauge "fix" on my T like a friend did with his PIWIS clone on my 981 spyder. Now I wonder if it will do the temp gauge mod on a .2. Can anyone confirm it does???

 

Keep in mind there are 2 potential pdk processes that you are referring to. The reset adaptations (Relearn in Porsche svc department parlance), and a PDK calibration. The relearn just wipes all the adaptations that have been learned based on how it has been used in the past. The calibration, on the other hand, is about a 12-15 minute process where the pdk re-calibrates shift linkage lengths and clutch engagement point, etc. all things that may change over time ... particularly clutch engagement points due to friction material loss,

@Porsche_nuts posted is a supposed call to the reset adaptations procedure ... although I cannot speak to whether it actually works,

Th re calibration, if supported in the tool, will be in the PDK module under special functions and it will be labeled as calibrate or re calibration. My launch x431 supports it .. the thinkdiag may as it is a Launch device.

I have attached a process from the service manual that is called as a predecessor to PDK calibration. It has some similarity to the process that @Porsche_nuts posted:

WM 2X00IN IMPORTANT INFORMATION ON ADAPTING THE DME CONTROL UNIT > TORQUE LOSS > ONLY NECESSARY FOR VEHICLES WITH PDK

Necessary after:

Re-programming DME control unit
Replacing DME control unit
Re-programming PDK control unit

Necessary before:
Re-calibrating PDK

Information

The accelerator pedal must always be pressed after approx. 1.5 minutes since each adaptation step is limited to 5 Nm.

How?

Engine idling:
1.1. Meet preconditions:
1. 1.1.1. Engine at operating temperature.

2. 1.2. Engine idling for 3 minutes without activating loads, press accelerator pedal once after approx. 1.5 minutes during this time.
3 1.3. Engine idling for 3 minutes with air conditioning switched on, press accelerator pedal once after approx. 1.5 minutes during this time.
4 1.4. Engine idling for 3 minutes with air conditioning switched on and transmission range engaged, press accelerator pedal once after approx. 1.5 minutes during this time.

Information
Adaptation values are deleted or stored in EEPROM when ignition is switched off after control unit run-on has ended.

This depends on the run-on period of the engine compartment purge fan.

The run-on period of the engine compartment purge fan AFTER ignition is switched off depends on the engine compartment temperature.

The run-on period is as follows at the following engine compartment temperatures:
1. < 45 °C: approx. 50 seconds
2. 45... 70 °C: approx. 200 seconds
3. > 70 °C: up to 20 minutes

5. 1.5. Switch off ignition.

 

Confirmed. I did the temp fix on my .2 using Thinkdiag

 

This is good information and makes sense. Thanks for the delineation.

This implies there’s a lot more to it than just the instructions there.
People did report good results just from those steps, but it could be expectation bias.

 

This is one of the main reason I ditch the stupid PCM

 

I’m going to attempt the temp reading on my 991.1 Can someone please tell me the exact way to do it on my ThinkDiag. I did go through the tread but still not sure of all the steps.
please forgive me I’m computer illiterate.
Thanks

 

Thanks!

 

I see there's a "new version" and a "hot version" on AliExpress. Which one did you guys get? I don't want to get the wrong one. I have an android tablet too.
