A696 - hall sensor, open circuit, closing movement, rear-end module
That is from the rear hallsensor with the red wire on the right coupling fastener. In most cases there are traces of rust as the housings will crack over years. Can be replaced with a cheaper one from an E88.
A692 - Microswitch, rear-end module closed, right
This is one of the two microswitches I recommend to replace after 10 years due to their aging. They are positioned on the top of the coupling fasteners on both side of the trunk lid.
