2010-2024 Audi Frameless Window Auto-Drop Inoperative TSB

Audi has issued Technical Service Bulletin (TSB) 64 24 97 2062618/4 to address a common problem affecting various models with frameless windows. Owners of 2010-2024 Audi vehicles may experience their frameless windows failing to auto-drop in freezing temperatures. This TSB supersedes an earlier bulletin, Group 64 number 23-95, dated November 10, 2023, providing updated information and solutions for this specific condition.

Symptoms

Owners may notice the following symptoms related to the Audi frameless window auto-drop function:

• Front and/or rear doors cannot be opened or closed properly in freezing weather.
• The windows are frozen to the outer window slot seals.
• The windows cannot drop when attempting to open or close the doors.
• The Audi frameless window auto-drop function is inoperative due to snow and ice build-up.

Diagnosis / Trigger Conditions

The technical background provided by Audi indicates that if snow and ice accumulate on the windows and the outer window slot seals, the mechanism designed to lower and raise the windows during door operation may not function. This blockage can occur even with the latest generation of window slot seals. The presence of snow and ice between the window and the outer window slot seals is the direct cause of the inoperative Audi frameless window auto-drop.

Important Warnings

Audi explicitly states a critical warning regarding this issue:

"Parts replacement does not solve this issue. Claims for replaced parts will be subject to review."

This means that attempting to replace window components will not resolve the problem and may lead to warranty claims being denied. The TSB is informational only and does not apply to any Audi Warranty for parts replacement.

Repair Procedure Summary

The recommended service procedure focuses on removing the ice and snow that impede the Audi frameless window auto-drop function. The steps are straightforward and can often be performed by the owner:

1. Using a plastic scraper, carefully remove any snow and ice from the windows. Refer to your vehicle's owner's manual for specific instructions on window care and cleaning.
2. If necessary, apply an Audi-approved solvent-free de-icer spray to the windows. This helps to melt any remaining snow or ice from the contact area where the outer window slot seal meets the window.
3. After clearing the ice and snow, check the operation of the doors and windows to ensure that the auto-drop function is working correctly when opening and closing the doors.

Required Tools or Parts

To address this issue, you will need:

• A plastic scraper.
• An Audi-approved solvent-free de-icer.

Owner Action

If you experience your Audi frameless window auto-drop function becoming inoperative in freezing weather, the first step is to clear any snow and ice from the windows and window seals using the methods described above. This is a maintenance item, and parts replacement is not indicated. Consult your owner's manual for further guidance on winter care for your vehicle's windows.
