Yes, the control is inside the PDK. Likely best it be checked with a PIWIS.

Try 9621

P1990 PDK Software monitoring A (or B) of signal processing unit

Possible fault causes:
- PDK control unit faulty

Fault effects:
- CAN alive counter freeze
- Engine speed limitation
- Transmission limphome indication in instrument cluster control unit

C150 DME control module, communication

Possible fault causes:
- No power supply for DME control module
- DME control module incorrectly coded
- Short circuit or open circuit in the CAN drive
- DME control module faulty (in most cases the cause is not the DME control module but incorrect coding!)

C152 PSM control module, communication

Possible fault causes:
- No power supply for PSM control module
- PSM control module incorrectly coded
- Short circuit or open circuit in the CAN drive
- PSM control module faulty (in most cases the cause is not the PSM control module but incorrect coding!)

Unless you know of some circumstance that may have affected these units (damage from accident, flooding, accidental short circuit, ... or even mice damaged wires) then you will likely need a Porsche PIWIS tester to run further diagnostics and re-programing.

Sometimes when there is a voltage spike to the system (like connecting a new battery) the programming can get "mixed up". When this happens the best thing to do is have a tech/shop with a PIWIS re-program the affected control module(s). I think it very rare to replace a DME if most everything but one or two items are not working.

As long as the majority are in the 1-3 range then it is usually considered good.

In my experience when you fix a problem that affects the "Ready" state it takes some time of driving to accumulate enough good test results to change the state. I have seen this with both O2 sensors and SAI issues.

That part does not show in the parts list so I think you are looking at a salvage yard or replacing the whole under deck lid cover. Sorry.

Hmm... i think the GT2 only has the one opening for the air filter cool air intake on the right side.

Perhaps an aftermarket spoiler?

Ok - Model and year of the car please?

Did you install a GT2 spoiler/rear lid?

Hi, thank you for the code unfortunately  it didn't unlock the radio.  I tried 4700 thru 4722.  Any chance there is an alternate code?  Thanks.

Did you use the procedure in the Lost Radio Code FAQ  to get the correct serial number (in the display)?

If not, please do so and re-submit the correct serial number.
