2022-2023 Audi MIL P240700 Evap Leak Detection TSB

Audi has released Technical Service Bulletin (TSB) 02 24 04 2066675/8 to address instances where the Malfunction Indicator Lamp (MIL) illuminates in various 2022-2023 Audi models equipped with gasoline engines. This TSB specifically targets vehicles that store Diagnostic Trouble Code (DTC) P240700, indicating an issue with the evap leak detection pump circuit. Owners experiencing an Audi MIL P240700 should be aware of the temporary nature of the current dealer action.

Revision History

This Technical Service Bulletin, 02 24 04 2066675/8, was issued on May 10, 2024. It supersedes a previous bulletin, Group 01 number 24-17, which was dated April 4, 2024. The bulletin has undergone several revisions, with revision 8 updating the header to include additional models, revision 7 on April 4, 2024, also updating the header, and revision 6 on November 22, 2023, for similar header updates.

Symptoms

The primary symptom owners will notice is the illumination of the Malfunction Indicator Lamp (MIL), commonly known as the check engine light. This light indicates that the vehicle's onboard diagnostic system has detected a fault.

Fault Codes / DTCs

When the MIL is illuminated, technicians will find the following Diagnostic Trouble Code (DTC) stored in the Engine control module (-J623-, address word 001):

Code	Description
P240700	Evap emission control system leakage diagnosis pump current fluctuating

This DTC is typically stored as Passive/Static, meaning the fault may not be actively occurring but was detected at some point. The TSB specifies that the event memory should not contain any other relevant entries for this specific issue.

Important Warnings for Owners

Audi explicitly states important guidelines for this condition, particularly regarding repairs. Owners should be aware that a permanent solution is currently under development and is expected to be available by the end of the second quarter of 2024, though this timeline is subject to change. Crucially, do not replace any components for this condition since it will not resolve the customer's concern. This warning prevents unnecessary repairs and costs, as current part replacements will not fix the underlying issue causing the Audi MIL P240700.

Current Status and Production Solution

Audi indicates that a production solution for the P240700 fault is currently under development. The Technical Service Bulletin will be updated once more information and a definitive solution become available. This approach highlights that the issue is recognized by the manufacturer, and a comprehensive fix is being engineered.

Service Procedure Summary

For technicians, the TSB outlines a straightforward service procedure to manage the P240700 DTC in the interim. The first step involves deleting the stored DTC P240700 from the vehicle's system. After clearing the code, the vehicle can be released back to the customer. Technicians are instructed to explain to the customer that while the MIL may be off, a permanent solution is anticipated by the end of Q2 2024. It is critical to emphasize that no component replacement should be performed for this condition. Finally, a Pending Service Solutions (PSS) record must be created in the PSS application via Access Audi or the Technical Assistance page in Elsa, ensuring proper tracking of the issue.

Warranty Information

This Technical Service Bulletin 02 24 04 2066675/8 is explicitly stated to be informational only and is not applicable to any Audi Warranty. This means that any actions taken under this bulletin, such as clearing the DTC, may not be covered under standard warranty terms. Owners should clarify any potential costs with their dealer.
