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) or,
as an alternative, isopropyl alcohol. Reinstall the level sensor.

cleaner.

2.

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).

3.

Saturate the tip of a cleaning brush with a rigid stem and long
enough to reach the probes (approximately 10”) with allpurpose cleaner D 009 401 04 or isopropyl alcohol. 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).

D 009 401 04 to the tip of a humming bird
feeder cleaning brush. The cleaning brush
can alternatively be saturated with
isopropyl alcohol.

4.

Thoroughly clean the sensor probes (Figure 4).

5.

Refill the reservoir with the correct type and concentration of
solvent. Windshield washer fluids found in the Audi Top
Service Supplies and Touch Up Paint eStore with a 35% premix are suitable for temperatures down to -30 °C (-22° F) and
contain no rain repellents. For freeze protection below this
temperature range Windshield Washer Fluid Concentrate
ZAW 096 311 B can be used and mixed according to the table
below (Figure 5). This solvent can be adjusted for freeze
protection to -32° C (-25° 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.

washer fluid concentrate.

Note:
Dealers in states such as California which have a restriction on windshield washer solvent VOC content can use
Audi Windshield Washer Fluid – 35% pre-mix – (55 gallon) available from the Audi Top Service Supplies &
Touch-Up Paint eStore as an alternative. This solvent contains no water repellents and has freeze protection to 22° F.
6.

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 light-dark
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.

refractometer.
