Is there an RS6 specific wiring diagram out there - the AllData site doesn't have one specific to this car. Have unplugged everything we think is on that fuse but it's still popping when turning the key.

Also fwiw found a shifter lockout workaround per this youtube video that works, so can at least drive the car now (basically remove trim surround at shifter, then straight down at the Front-Left of the shifter there is a white plastic bit that you can push forward to unlock the shifter lock):
