2024 Audi Key Adaptation Fault: Status 13 Security Denied

Owners of various 2024 Audi models, including the Audi Q7, may encounter a specific issue when attempting to adapt new or additional keys to their vehicle. This problem is detailed in Audi Technical Service Bulletin (TSB) 2071336/1, issued on September 8, 2023. The TSB addresses a key adaptation fault where the immobilizer test plan displays a 'Status: 13 / Security access denied' message.

This Audi key adaptation fault prevents proper key programming and is a known condition due to recent infrastructure upgrades to Audi's backend systems. The TSB outlines a temporary but effective solution involving a specific SVM code to bypass the security access denial.

Symptoms and Fault Codes

When attempting to adapt additional keys, technicians will observe a specific error message within the immobilizer test plan. The verbatim message displayed is:

"The parameterization on the following control module could not be performed: 0046- central module of comfort system Status: 13 / Security access denied ..."

This message may also appear with the specific diagnostic code "Status 13 / Security access denied - 7F2E33", indicating a failure in the parameterization process for the comfort system's central control module.

Important Warnings for Owners

Audi notes a critical detail for vehicles equipped with high-voltage components, such as Audi e-tron models. If a high-voltage charging cable is connected during the key adaptation process, it can lead to an interruption of the parameterization. Owners of e-tron vehicles should ensure the charging cable is disconnected before any key adaptation procedures are attempted.

Diagnosis and Trigger Conditions

The Audi key adaptation fault is specifically triggered when new or additional keys are being adapted to the vehicle. The error occurs during the immobilizer test plan, preventing the successful parameterization of the '0046- central module of comfort system'. This issue is a direct result of ongoing backend system upgrades at Audi.

Repair Procedure Summary

To resolve the 'Status: 13 / Security access denied' message and successfully adapt keys, technicians should follow a specific procedure outlined in TSB 2071336/1:

1. Restart the Immobilizer Test Plan: Begin by restarting the immobilizer test plan within the diagnostic tool.
2. Follow On-Screen Prompts: Proceed through all prompts displayed on the diagnostic screen.
3. Select SVM Code Option: When prompted to check for an SVM code, select the option labeled "2 - SVM code available".
4. Enter SVM Code: Input the specific SVM code UNECEKW2944 into the system.
5. Continue Test Plan: Resume the immobilizer test plan as normal. This SVM code allows the system to bypass the security access denial and complete the key adaptation.

This procedure is a temporary measure. Audi anticipates that once the backend system updates are fully completed, this TSB will be retired, and the normal key adaptation process will resume without the need for a special SVM code.

Required Tools

Technicians will need specific diagnostic tools to perform this procedure:

• VAS 6160/VAS 6150: This refers to the VAS tester, which must be running the current version of ODIS (Offboard Diagnostic Information System) on Windows 10.

Warranty Information

What Owners Should Do

If you own a 2024 Audi model and are experiencing issues with key adaptation, particularly if you see the 'Status: 13 / Security access denied' message, you should contact your authorized Audi service center. Inform them about the specific error message and refer to Audi TSB 2071336/1. The service center will have the necessary tools and the SVM code UNECEKW2944 to address this Audi key adaptation fault and successfully adapt your keys.
