Thank you all for this thread. It helped me get rid of the airbag light and passed inspections on my 2004 Cayenne Turbo.
Bought the Durametric Enthusiast version.
It showed the 1217 driver side code. Erase the code, but it came back. So, next step is to remove the seat to see what's going on.
Removed the 4 bolts for the driver seat.
Disconnected the battery "-"
Disconnected all the connectors associated with the main cable coming from the floor.
Found the black wire to the black wire and the blue wire to the blue wire were already clamped tight and nicely wrapped
