Such door contact switch (1; here it is dismantled) is only on back doors under a rubber nozzle (2).

At the left: in cars with illumination of a mirror for a make-up it is possible to squeeze out carefully an insert of a mirror (1) of a frame of a sun-protection peak. Then the microswitch (2) and both sofitny lamps (3 and 4) will be visible to illumination of a mirror.

The door contact switch of a lamp for illumination of salon

On forward doors in Audi A4 there are no more traditional door contact switches. Instead of them contact "is integrated into a servomotor of the central lock doors are closed".

In a different way the situation is with back doors: here in a doorway the traditional contact switch is installed. It sends a direct signal of the provision of a door to the control unit of the central lock as it does contact of forward doors. Violations in operation of this switch arise when:

  • press the pin of the switch gets jammed in directing or it is bent. Replace the switch;

  • contact surface of the switch with the fixing screw or contacts of the socket were oxidized. Remove an oxide layer with an emery paper or a sharp screw-driver.

The door contact switch is screwed on a door pillar only by one screw with a crosswise head. That to dismantle it, remove a rubber nozzle, unscrew the screw and take out the switch.
