Default 992.1 ACC fault code U112100

I have the classic fault with ACC
ACC not available
Driving permitted
Inspection necessary

I've turned the car off and on, driven 60 miles, left it overnight, disconnected the battery for 30 mins but no luck. PIWIS is showing ACC BOSCH AU65X 002 - U112100 - FAULT TIMEOUT_VZE 01

Any ideas?

I believe it may be a wiring issue, does anyone have info on the sensor/camera connector and wiring layout behind the bumper?

You can ignore the "Cut existing lines", that's for a retrofit. The connector type is L72A8 (part number 4FO-972-708).
