Looking at the parts list drawing I would suspect that the only possibility is playing with the inner nut shown on the drawing, on the electrical connector side. Mark it's current position in relation to the axle and try loosening/tightening very slightly. Is there any end play that you can notice of the hub on the axle or any side play at the rim of the wheel?

Otherwise I would be on the phone to SRAM technical support Monday seeking their advice.
