61 35 179 Replacing and installing (replacing) the solar rain/light sensor and condensation sensor

IMPORTANT: Read and comply with notes on PROTECTION AGAINST ELECTROSTATIC DAMAGE (ESD PROTECTION) .

Necessary preliminary tasks:

Remove INTERIOR MIRROR

Removal:

Disconnect connector (1).

Unlock the rain/light/solar and condensation sensor (2) from the metal spring (3).

To do so, compress the metal spring (3) from both sides, insert a screwdriver (4) from the side and lift the latch mechanism.

IMPORTANT:

Risk of damage.

After loosening lock, wait approx. 30 min. at 20°C for silicone surface to relax.

Pull the rain/light/solar and condensation sensor (1) slowly from holder (2) in direction of arrow.

NOTE: When replacing the windscreen, only remount the rain/light/solar and condensation sensor (1) after disassembly of the windscreen.
Pull off the rain/light/solar and condensation sensor (1) slowly while observing from outside the release of the silicone surface.
The silicone surface must evenly loosen from the windscreen, if applicable, pull off slower.

IMPORTANT:

Risk of damage.

The silicone-coated surface (1) and the printed circuit board (2) on the rain/light/solar and condensation sensor must not be touched or damaged.

When replacing the windscreen, immediately install the rain/light/solar and condensation sensor into the new windscreen following removal.

IMPORTANT:

Risk of damage.

The surface (1) on the windscreen must not be touched or damaged.

The separating oil of the rain/light/solar and condensation sensor might have left easily removable residues in the area (1).

This is not considered a damage of the rain/light/solar and condensation sensor.

Remove all residues of the separating oil inside and outside the area (1).

Installation note:

Connect connector (1) only after the rain/light/solar and condensation sensor has been locked.

Press on the rain/light/solar and condensation sensor (2) at the metal spring (3) in a centered position.

To lock, consecutively press down both sheet metal tabs (4) on each side.

Connect connector (1) with the rain/light/solar and condensation sensor (2).
