Spoiler deployment woes
Gents, I've tried everything and my spoiler won't deploy on my 15 CGTS.
LED on the spoiler button does not illuminate at all, completely dead, tried the following:
Replaced the spoiler fuse
Replaced the spoiler motor behind the bumper
Replaced the button/switch console
Any ideas? is there a relay for this thing? Cheers

adding features such as Sport Chrono, PSE, or PASM, to a car that didn't have them from the factory, yes

Not enough information. When did it stop working? Was work done on the car immediately prior to the failure? If so, was the work done anywhere along the electrical path of the spoiler system?
Did you apply 12v to the new motor to verify it functioning?
If it were me, I would start with the electrical schematic and work backwards from the motor to find where you have power/signal loss or perhaps from the switch. With the schematic, you should be able to find some test points to check for continuity. If work was done involving pulling interior panels, I would look for an uncoupled connector.

I did not check for basic 12V functionality, I'll try that on the old one and report back, seeing as the replacement motor is installed in the car currently.

Not sure what fuse you replaced, but the only fuse shown in the circuit drawings is for the power to the Center Console Button Module. It's in the Left Front Fuse Box, Row C #1, 15A. It powers some other important stuff so likely a non-issue.
There are no relays in the circuit. The spoiler Extend and Retract functions are controlled by the Rear Body Control Module. All wiring from the Spoiler Drive is routed to the rear BCM.
The CAN network handles comms between the Center Console Button Module and other associated modules that have inputs to the spoiler function.
Here's the text from the Porsche Service Manual regarding programming when replacing the switch module.
