2022-2023 Audi MIL on DTC P240700 Evap Leak

Symptoms of the Audi P240700 Evap Leak

Owners of affected 2022-2023 Audi vehicles may notice their Malfunction Indicator Lamp (MIL), commonly known as the Check Engine Light, is illuminated on the dashboard. This is the primary symptom associated with the Audi P240700 Evap leak condition.

Understanding DTC P240700

When the MIL illuminates, a diagnostic trouble code (DTC) is typically stored in the vehicle's engine control module. For this particular issue, the DTC recorded is P240700. This code specifically indicates an "Evap emission control system leakage diagnosis pump current fluctuating." The code will be stored as Passive/Static in the Engine control module, identified as -J623- (address word 001). It's important that no other relevant entries are present in the event memory for this TSB to apply.

Important Warnings for Owners

Audi has provided crucial guidance regarding this issue. A permanent solution for the Audi P240700 Evap leak is expected to be available by the end of the third 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. Replacing parts prematurely will not fix the underlying issue and may result in unnecessary costs.
