2025 Audi A5 Windshield Washer Not Working TSB

Symptoms

Owners of affected vehicles may experience that the "windshield washer does not work." This can manifest as the washer system delivering "too little" fluid, being "plugged," or exhibiting "functionality -> cannot be switched on/activated" or "functionality -> irregular" behavior. The core issue is that the windshield washer system fails to spray fluid onto the windshield when activated, hindering visibility.

Diagnosis and Trigger Conditions

The primary cause for the Audi A5 windshield washer malfunction is typically a squashed or kinked hose near the hood hinge, specifically identified as the windshield washer system hose located at the left front. This can occur due to two main reasons:

1. Overtightened Cable Tie: A cable tie may have been tightened excessively, blocking or pinching the washer hose.
2. Incorrectly Positioned Clips: The clips securing the hose may have been positioned improperly during manufacturing.

In both scenarios, the hose becomes obstructed, preventing the washer fluid from reaching the nozzles. Technicians will inspect the hose routing and clip positions at the hood hinge to identify the exact point of restriction. Figure 1 in the TSB visually illustrates a kinked hose, while Figure 2 shows the correct routing.

Important Warnings

Owners and technicians should note the following critical information regarding this repair:

• Hose Replacement: If the hose is found to be irreparably damaged or if the repair procedure cannot resolve the kink, the entire hose assembly must be replaced. The TSB states: "If a repair is not possible, the hose must be replaced completely. To do so, please replace the entire hose with clips and send it in to Audi of America."

Repair Procedure Summary

This Technical Service Bulletin 2079245/1 outlines a repair procedure that often does not require replacing the entire washer hose for the Audi A5 windshield washer system. The steps involve correcting the hose's position and condition:

1. Initial Inspection: Technicians first check the distance between the claw clip and the pine-tree clip, which should be 160mm (+5mm maximum tolerance), as depicted in Figure 3. They also verify that the claw clip is oriented at 90 degrees to the pine-tree clip to ensure correct hose positioning in the engine compartment and hood without twisting. This involves releasing both clips to check their orientation and the extrusion line on the hose for twisting.
2. Hose Kink Correction: If a kink is present in the EPDM hose, it can often be "massaged" out using heat from a hot air blower. The goal is to make it possible to bend the hose 180 degrees without it kinking again.
3. Clip Securing and Wrapping: Secure the claw clip, part number 3D0971838 E or M, with a cable tie, ensuring the hose is not squashed. Then, wrap this clip with fabric adhesive tape, part number N10591902. The pine-tree clip, part number N91144301, should also be positioned correctly and wrapped in tape. Figure 4 provides a visual guide for securing and wrapping the clips.
4. Functionality Check: After completing the repair, the technician must close the hood and check the functionality of the windshield washer system to ensure it works correctly. Figure 5 illustrates this final check.
