2009-2026 Audi Gearbox Complaint Technical Information TSB

Audi Technical Service Bulletin (TSB) 37 24 22 2074826/1 offers crucial guidance for technicians on how to properly document and submit technical repair requests related to gearbox complaints. This TSB is not a repair procedure itself, but rather a framework to ensure that all necessary information is collected for effective diagnosis and support for various Audi models from 2009 to 2026, including the Audi e-tron. Accurate and complete data is essential for processing any technical repair query, especially concerning complex issues like Audi e-tron gearbox complaints.

This bulletin emphasizes that it contains the fundamental work steps and basic information required for providing the best possible technical support. It clarifies that a technical repair query can only be processed if all requested information is available. It also states that this article is solely for submitting technical repair queries and cannot be used as workshop findings for customer complaints or for billing purposes.

Gathering Information for Gearbox Complaints

To address gearbox complaints effectively, technicians must follow a structured approach to information gathering. This includes checking for fault codes, collecting diagnostic data, inspecting transmission fluids, and meticulously describing symptoms.

Checking for Fault Codes

One of the initial steps involves checking for any event memory entries (fault codes) within the gearbox control unit or other relevant systems such as the engine, Electronic Stability Control (ESC), or data bus diagnostic interface. If fault codes are present, technicians are instructed to work through Guided Fault Finding procedures.

Submitting Diagnostic Data

Technicians are required to send the current diagnostic log online and make all gearbox measured values available for review. This comprehensive data helps in understanding the operating conditions and parameters of the gearbox at the time of the complaint.

Inspecting Transmission Fluids

Checking the oil level and quality of the transmission fluid is a critical step. If metal swarf (small metallic particles) is visible in the fluid, technicians must take photos with a scale for reference and attach them to the Doc-IT system. Additionally, any leaks must be precisely located using methods like leak detection spray, followed by a test drive, and relevant photos uploaded to Doc-IT.

Performing a Glycol Test

For specific automatic gearboxes, a glycol test can be performed if glycol contamination is suspected in the automatic transmission fluid (ATF). Applicable gearboxes include VL300, VL381, AL420, AL600, AL651, AL551, AL552, AL952, DL501, DL382, and DQ381, corresponding to workshop designations like 01J, 0AW, 09L, 0AT, 09E, 0B6, 0BK, 0D5, 0D6, 0B5, 0CK, 0CL, 0CJ, and 0GC.
