2021-2024 Audi SFD Diagnostic Work Requirements TSB

Audi has released Technical Service Bulletin (TSB) 2069282/1 to inform technicians and owners about the critical requirements for performing diagnostic work on certain 2021-2024 Audi models. This bulletin specifically addresses the need for proper SFD (Vehicle Diagnostics Protection) privileges when servicing vehicles, particularly when dealing with control module coding, adaptation, or part replacement. Understanding these requirements is crucial to ensure proper repairs and avoid potential issues, especially concerning Audi S3 SFD diagnostic work.

What is SFD (Vehicle Diagnostics Protection)?

SFD, or Vehicle Diagnostics Protection, is a security feature implemented in newer Audi vehicles built on the MQB and MEB platforms. This system is designed to safeguard the vehicle's electronic control units (ECUs) against unauthorized or malicious software manipulation. It ensures that only authorized personnel with the correct credentials can perform sensitive diagnostic and programming tasks.

When SFD Privileges are Necessary

According to TSB 2069282/1, SFD privileges are required whenever service involves:

• Performing control module coding.
• Adapting control modules.
• Adjusting basic settings within control modules.
• Replacing parts that necessitate a replacement test plan.

This applies to SFD-enabled vehicles, including the Audi A3 (8Y), Q3 (F3 since MY2021), and Q4 (F4) models. For any of these tasks, technicians must be logged into their ODIS account with the appropriate SFD privileges.

Critical Warnings for Service and Parts

Audi emphasizes a significant warning regarding SFD-enabled vehicles. It states that working on such a vehicle without being logged into an ODIS account, or without sufficient SFD privileges, carries severe risks. Specifically, it may:

• Prevent the completion of necessary test plans.
• Cause new parts to "irrevocably become unusable due to it being locked against manipulation" when running a replacement test plan.
• Lead to warranty claims for parts rendered unusable due to insufficient SFD account privileges being denied.

This means that improper procedures can result in costly damage and voided warranties, highlighting the importance of correct Audi S3 SFD diagnostic work protocols.

What Technicians Must Do

To avoid these issues, technicians performing diagnostic work on affected Audi models must ensure they are logged into their ODIS account and possess the correct SFD privileges. If an ODIS account lacks these necessary privileges, the local IT support should be contacted immediately to resolve the issue before proceeding with any service.

This TSB, 2069282/1, is informational and does not apply to any Audi warranty directly. However, adhering to its guidelines is crucial for proper vehicle maintenance and to prevent complications with parts and warranty coverage.
