Symptoms
Owners of 2012-2024 Audi vehicles may experience a specific issue where the driver information system (DIS) displays the message: "The washer solvent level warning is on". This warning appears despite the washer solvent reservoir being full. Crucially, there is no actual functional restriction in the windshield washer system, meaning the wipers and washer fluid still operate correctly. This false Audi washer solvent level warning can be frustrating for vehicle owners.
Technical Background
The root cause of this false warning lies with the sensitivity of the washer solvent level sensor, designated G33. This sensor's operation is highly dependent on the type, concentration, and presence of additives in the washer solvent currently in the tank. If the solvent's composition is incorrect or if additives contaminate the sensor, its sensitivity can be reduced. This leads to inaccurate readings and the persistent low-level warning, even when the reservoir is full. The sensor relies on the precise composition of the solvent to provide an accurate message on the solvent level.
Important Warnings
Audi has issued a critical note regarding this issue: "It is not necessary to replace the windshield washer solvent level sensor when the cause of failure is contaminated sensor probes or incorrect washer solvent solution. Warranty claims for replacement of washer solvent level sensors that are found to not be faulty will not be reimbursed." This emphasizes that proper diagnosis and cleaning are the primary solutions, and unnecessary sensor replacements will not be covered under warranty.
Revision History
This Technical Service Bulletin, identified as 92 23 33 2038151/13, was issued on February 6, 2023. It supersedes Technical Service Bulletin Group 92 number 22-30, which was dated July 14, 2022. The bulletin has undergone several revisions:
- Revision 13: Updated Labor Operations within the Warranty section.
- Revision 12 (July 14, 2022): Revised the header to include Model Year 2022 - 2024 vehicles and updated the Warranty section to include Q4 e-tron and Audi e-tron GT models.
- Revision 11 (December 20, 2019): Revised the Required Parts and Tools section, specifically updating the quantity information.
Repair Procedure Summary
Addressing the Audi washer solvent level warning involves cleaning the G33 sensor and ensuring the correct washer fluid concentration. The procedure varies slightly depending on the vehicle model:
- For most Audi vehicles (excluding A3 Sedan, A3 Cabriolet, and Q4 e-tron): The washer fluid reservoir must be emptied. The level sensor is then removed, and its probes are cleaned using all-purpose cleaner D 009 401 04 (as shown in Figure 1, which depicts the cleaner product) or, as an alternative, isopropyl alcohol. After thorough cleaning, the sensor is reinstalled.
- For Audi A3 Sedan, A3 Cabriolet, and Q4 e-tron: In these models, the washer solvent level sensor is not easily removable. Technicians must remove the entire reservoir and its filler neck to gain access to the sensor probes (Figure 2 illustrates the sensor probes as viewed through the tank opening). A cleaning brush with a rigid, long stem (approximately 10 inches) is recommended. This brush should be saturated with all-purpose cleaner D 009 401 04 or isopropyl alcohol (Figure 3 shows the application of cleaner to a hummingbird feeder cleaning brush, which serves as an example of a suitable tool). The sensor probes are then thoroughly cleaned (Figure 4 demonstrates the cleaning process).
After cleaning, the reservoir must be refilled with the correct type and concentration of windshield washer fluid. Audi recommends using fluids from the Audi Top Service Supplies and Touch Up Paint eStore with a 35% pre-mix, which are suitable for temperatures down to -22° F and are free of rain repellents. For colder climates requiring protection below this temperature, Audi Windshield Washer Fluid Concentrate ZAW 096 311 B (Figure 5 shows the product bottle) can be used and mixed according to specific guidelines.
To ensure proper concentration, a T10007A refractometer (Figure 6 depicts the refractometer tool) is used. A drop of washer fluid is placed on the refractometer's glass. When viewing the refractometer, a light-dark border can be clearly recognized. Using the scale on the right (Figure 7 shows the scale view), the concentration of the solvent is adjusted to accommodate current weather conditions.
Concentration Guidelines
When using Windshield Washer Fluid Concentrate ZAW 096 311 B, the following mixing ratios with water are recommended to achieve specific freeze protection levels:
| Freeze protection | Windshield Washer Fluid Concentrate ZAW 096 311 B | Water |
|---|---|---|
| -16 °C (3° F) | 1 part | 3 parts |
| -30 °C (-22° F) | 1 part | 2 parts |
| -32 °C (-25° F) | 1 part | 1.5 parts |
Required Tools or Parts
To address the Audi washer solvent level warning and similar issues, specific parts and tools are required:
