Due to aging the plastic clips holding the LED cover become fragile and break off.
This lets the moisture to enter the LED casing. If not fixed the LED will burn out and can even cause [[door control module]] damage.
The moisture can be dried out using a heat gun and the broken clip can be fixed using a paper clip (see below).

Function prerequisites:

The light reaching the surface of the mirror is reflected to a greater
or lesser extent depending on the magnitude of the control
voltage. The control voltage is regulated by the interior rearview
mirror unit (A67) (master) and the overhead control panel control module (N70).
Two discrete leads are connected to the left front door control module (N69/1)
for this purpose (vehicles with right-hand steering: right front door control module ((N69/2)).
Regulation is accomplished depending on the ambient light and
the light reaching the mirror. These two variables are measured by
the ambient light sensor (A67h2) in the interior rearview mirror
housing (rear) and the automatic dimming interior rearview
mirror sensor (A67h1) in the mirror glass in the interior rearview
mirror unit.
If one of the interior lights is switched on or the CAN message
"Reverse gear engaged" is received from the electronic ignition/
starter switch control module (N73), the exterior rearview mirror
as well as interior rearview mirror become brighter.

  • Term.15R or 15 ON

The left and right exterior mirrors can be electrically adjusted via the switches in the switch train for exterior mirror adjustment with fold in/out function (S50/1) in the front left door control module (N69/1) (RHS vehicle: Front right door control module (N69/2)). The following settings are possible:

  • Horizontal mirror glass adjustment
  • Vertical mirror glass adjustment
  • Mirror housing folding-in (garage position) and folding-out (driving position)

The adjustments are carried out by the motors in the left electrically adjustable and heated exterior mirror (M21/1) and the right electrically adjustable and heated exterior mirror (M21/2). The motors are actuated via the front left door control module (N69/1) and the front right door control module (N69/2).

The memory function (special equipment) can be used to call up stored mirror settings. Setting the parking position of the exterior mirror on the front passenger's side enables the driver to check the distance of the relevant rear wheel from the edge of the curb when reversing into a parking space.

Exterior rearview mirror adjustment switch

The switches for adjusting the exterior rearview mirrors are located in a separate assembly in the exterior mirror adjustment switch with mirror fold-in/out (S50/1) on the left front door control module (N69/1) (vehicles with right-hand steering : right front door control module (N69/2)).

Left front door control module (N69/1) (left-hand steering)

  • S50/1 - Exterior mirror adjustment switch with mirror fold-in/fold-out feature
  • S50/1s1 - Exterior mirror adjustment up/down switch
  • S50/1s2 - Exterior mirror adjustment left/right switch
  • S50/1s3 - Exterior mirror changeover switch to left mirror

  3. Adjustment button

Exterior rearview mirror adjustment motor

The motors for adjusting the mirror glass and housing are located in the left electrically adjustable and heated exterior rearview mirror (M21/1)/right electrically adjustable and heated exterior rearview mirror (M21/2).

  • M21/1 - Left electrically adjustable and heated exterior rearview mirror
  • M21/1m1 - Vertical mirror adjustment motor (up/down)
  • M21/1m2 - Horizontal mirror adjustment motor (in/out)
  • M21/1m3 - Mirror fold-in motor
  • M21/2 - Right electrically adjustable and heated exterior rearview mirror
  • M21/2m1 - Vertical mirror adjustment motor (up/down)
  • M21/2m2 - Horizontal mirror adjustment motor (in/out)
  • M21/2m3 - Mirror fold-in motor

The left exterior rearview mirror glass can be adjusted vertically and horizontally with the vertical mirror adjustment motor (up/down) (M21/1m1) and horizontal mirror adjustment motor (in/out) (M21/1m2) in the left electrically adjustable and heated exterior rearview mirror (M21/1). The right exterior rearview mirror glass can be adjusted vertically and horizontally with the vertical mirror adjustment motor (up/down) (M21/2m1) and horizontal mirror adjustment motor (in/out) (M21/2m2) in the right electrically adjustable and heated exterior rearview mirror (M21/2). The housing of the left/right exterior rearview mirror can be folded in (garage position) and out (driving position) with the mirror fold-in motors (M21/1m3)/(M21/2m3).

The motors are DC motors. Two potentiometers each are located on the motor shafts (M21/1m1)/(M21/2m1) and (M21/1m2)/(M21/2m2) for position recognition. The motors for outside rearview mirror (with fold-in/out feature) (M21/1m3)/(M21/2m3) are not equipped with a position recognition feature.

The motors turn to the left or right depending on the polarity of the actuating voltage. Actuation is accomplished by the left front door control module (N69/1)/right front door control module (N69/2).

Exterior rearview mirror position measurement function

A potentiometer for measuring the position is located on each of the shafts for the vertical mirror adjustment motors (up/down) (M21/1m1)/(M21/2m1) and horizontal mirror adjustment motors (in/out) (M21/1m2)/(M21/2m2) in the left and right exterior mirrors.

Fold in left/right exterior mirror function

The left and right exterior mirror housings can be electrically folded in and out. Via the switches in the switch train for exterior mirror adjustment with fold in/out function (S50/1) in the front left door control module (N69/1) (RHS vehicle: Front right door control module (N69/2) ), the left/right exterior mirror housing can be moved to the garage position (mirror housings folded in) or the driving position (mirror housings folded out). The switch statuses of the switches for folding the exterior mirror in (S50/1s4) and the switches for folding the exterior mirror out (S50/1s5) are read in by the front left [[door control module]] (N69/1) (RHS vehicle: Front right door control module (N69/2)) inserted and placed onto the CAN as a message for the door control module on the front passenger's side.

The front left door control module (N69/1) and the front right door control module (N69/2) then actuate the motor for folding the mirror in (M21/1m3) and the motor for folding the mirror in (M21/2m3) in the left and right exterior mirror housings.

Up to 31.05.01 the fold in exterior mirror switch (S50/1s4) or the fold out exterior mirror switch (S50/1s5) must be actuated until the mirror housings are in the desired position.

As of 01.06.01 the fold in exterior mirror switch (S50/1s4) or the fold out exterior mirror switch (S50/1s5) merely have to be touched, and the mirror housings are automatically moved to the desired position.

Heating left/right exterior rearview mirrors function

  • 1 - CAN-message: outside temperature
  • 2 - CAN-message: dew point
  • 3 - CAN-message: "Generator running (C.61)"
  • B14 - Outside temperature sensor
  • B31/1 - A/C multifunction sensor
  • G2 - Generator
  • K40/6 - Left front fuse and relay module
  • K40/7 - Right front fuse and relay module
  • M21/1r1 - Left mirror heater
  • M21/2r1 - Right mirror heater
  • N10/6 - Left front SAM control module
  • N10/7 - Right front SAM control module
  • N22 - A/C pushbutton control module
  • N69/1 - Left front door control module
  • N69/2 - Right front door control module

Function prerequisites:

  • Voltage not too low or too high
  • C.61 ON

The left mirror heater (M21/1r1) in the left electrically adjustable and heated exterior rearview mirror (M21/1) and the right mirror heater (M21/1r1) in the right electrically adjustable and heated exterior rearview mirror (M21/2) consist of a heater resistor connected in series with a PTC resistor. The heater resistor is located on the rear of the mirror glass to which it is permanently bonded. The power supply and regulated switching on and switching off of the heater resistors is accomplished by the left front door control module (N69/1)/right front door control module (N69/2). The mirror heater is controlled in relation to the outside air temperature (CAN message from the left front SAM control module (N10/6)) and the dew point (CAN message from automatic A/C pushbutton control module (N22)).

Automatic dimming feature for exterior rearview mirror on driver's side function

For vehicles with option code 249 - INSIDE AND OUTSIDE MIRROR AUTOMATIC DIMMING the exterior rearview mirror on driver's side (M21/1) can be dimmed electro-chromatically.

The inside rearview mirror (A67) in combination with the overhead control panel control module (N70) serves as master for dimming the electrically adjustable and heated left outside mirror (M21/1).

  • 1 - CAN-message: "Shift lever position"
  • 2 - CAN-message: "Reverse gear engaged"
  • A67 - Interior rearview mirror unit
  • M21/1 - Left electrically adjustable and heated exterior rearview mirror
  • M21/2 - Right electrically adjustable and heated exterior rearview mirror
  • N15/5 - Electronic shift lever module control module
  • N70 - Overhead control panel control module
  • N73 - Electronic ignition/starter switch control module

Function prerequisites:

  • Voltage not too low or too high
  • C.15R or C.15 ON

The light reaching the surface of the mirror is reflected to a greater or lesser extent depending on the magnitude of the control voltage. The control voltage is regulated by the interior rearview mirror unit (A67) (master) and the overhead control panel control module (N70). Two discrete leads are connected to the left front door control module (N69/1) for this purpose (vehicles with right-hand steering: right front door control module ((N69/2)).

Regulation is accomplished depending on the ambient light and the light reaching the mirror. These two variables are measured by the ambient light sensor (A67h2) in the interior rearview mirror housing (rear) and the automatic dimming interior rearview mirror sensor (A67h1) in the mirror glass in the interior rearview mirror unit.

If one of the interior lights is switched on or the CAN message "Reverse gear engaged" is received from the electronic ignition/ starter switch control module (N73), the exterior rearview mirror as well as interior rearview mirror become brighter.
