The washer solvent level warning is on in the driver information system (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 for all vehicles except A3 Sedan
and A3 Cabriolet, remove the level sensor. Clean the
sensor probes using all-purpose cleaner D 009 401 04
(Figure 1), then reinstall the level sensor.

For Audi A3 Sedan and A3 Cabriolet where the washer
solvent level sensor is not removable the sensor probes can
be cleaned by removing the reservoir, removing the filler
neck from the reservoir and gaining access to the sensor
probes (Figure 2).

Saturate the tip of a cleaning brush with a rigid stem and
long enough to reach the probes (approximately 10”) with
all-purpose cleaner D 009 401 04. A humming bird feeder
cleaning brush is shown in the illustration but any suitable
cleaning brush with a tip constructed of the appropriate
material will function well for this purpose (Figure 3).

4.

Thoroughly clean the sensor probes (Figure 4).

Figure 4. Cleaning the sensor probes.
5.

Refill the reservoir with the correct type and concentration
of solvent. Windshield cleaner concentrate with anti-freeze
G 052 164 M2 works best (Figure 5). 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.

Note:
Dealers in states such as California which have a restriction on windshield washer solvent VOC content can use

The concentration and freeze point can be checked using
the T10007A refractometer (Figure 6).

Figure 6. T10007A refractometer.
7.

Put a drop of washer fluid with the pipette on the glass of
the refractometer. When viewing the refractometer, a lightdark border can be clearly recognized. Using the scale to
the right (Figure 7), adjust the concentration of the solvent
to accommodate the current weather conditions.
