Technical Service Bulletin
Workshop findings:
• 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:

Empty the reservoir and for all vehicles except A3 Sedan, A3
Cabriolet, and Q4 e-tron, 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.

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 or isopropyl alcohol. A
hummingbird 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).

401 04 to the tip of a hummingbird feeder
cleaning brush. The cleaning brush can
alternatively be saturated with isopropyl
alcohol.

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.

Figure 5. ZAW 096 311 B 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 & TouchUp Paint eStore as an alternative. This solvent contains no water repellents and has freeze protection to -22° F.

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

Figure 6. T10007A refractometer.

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.
