Condition
The washer solvent level warning is on in the DIS, but the washer solvent level is correct. There is no functional
restriction in the windshield washer system.

Technical Background
The sensitivity of the washer solvent level sensor (G33) can be affected by the type, concentration, and the
presence of additives in the washer solvent currently in the tank. The operation of the level sensor relies on the
composition of the solvent to provide an accurate message on the solvent level. Incorrect concentration and the
presence of additives can contaminate the sensor and reduce its sensitivity.

Production Solution
Not applicable.

Service
If the washer solvent reservoir is full and the low solvent warning is on, proceed as follows:
1. Empty the reservoir and remove the level sensor. Clean the
sensor probes using all-purpose cleaner D 009 401 04
(Figure 1), then reinstall the level sensor.

2. Refill the reservoir with the correct type and concentration of
solvent. Windshield cleaner concentrate with anti-freeze G
052 164 M2 works best (Figure 2). This solvent can be
adjusted for freeze protection to -70° C (-94° F), prevents
washer jet contamination particularly on the “fan” type of
washer jet, and is highly effective in removing residues and
insects from the windshield.

3. The concentration and freeze point can be checked using the
T10007A refractometer (Figure 3).

4. Put a drop of washer fluid with the pipette on the glass of the
refractometer. When viewing the refractometer, a light-dark
border can be clearly recognized. Using the scale to the right
(Figure 4), adjust the concentration of the solvent to
accommodate the current weather conditions.
