2022 Audi Q8 MIL On with DTC P240700 Evap Leak

Audi has issued Technical Service Bulletin (TSB) 01 22 19 2066675/1, dated March 29, 2022, to address a specific condition affecting various 2022 Audi models equipped with a gasoline engine. This TSB focuses on instances where the Malfunction Indicator Lamp (MIL) illuminates, accompanied by a particular Diagnostic Trouble Code (DTC) related to the evaporative emission system.

This bulletin serves as an interim communication, informing technicians and owners about a known issue while a definitive repair solution is still under development. It provides crucial guidance on how to handle vehicles presenting with the specified symptoms and fault codes.

Symptoms

Owners of affected 2022 Audi vehicles may notice the following symptom:

• "MIL Light On" (Malfunction Indicator Lamp, commonly known as the Check Engine Light).

Fault Codes / DTCs

When diagnosing the issue, technicians may find the following Diagnostic Trouble Code (DTC) stored in the Engine control module, J623 (address word 001):

• P240700: Evap leak detection pump circuit

The TSB specifies that this DTC may be stored as "Passive/Static." This indicates that while the fault is present, it might not be actively occurring at the moment of diagnosis, or it has been recorded and stored in the vehicle's memory.

Diagnosis and Trigger Conditions

According to the TSB, the presence of the P240700 DTC in the Engine control module (J623) is the primary indicator for this condition. It is important that the vehicle's event memory does not contain any other relevant entries, suggesting that P240700 should be the sole or primary fault code related to the MIL illumination for this bulletin to apply. The technical background for this issue is currently listed as "Not Applicable" in the bulletin, indicating that further details on the root cause are pending.

Important Warnings for Owners

Audi has provided a critical instruction for this specific issue. Owners and technicians should be aware of the following:

• "Do not replace any components for this condition since it will not resolve the customer's concern." This means that attempting to replace parts related to the Evap leak detection pump circuit will not fix the underlying problem and is not recommended at this time. This warning prevents unnecessary repairs and costs.

What to Expect: Solution Under Development

Audi states that a permanent solution for the Audi Q8 MIL P240700 issue is currently under development. The bulletin indicates that a solution is expected to be available by the end of the 4th quarter of 2022, though this timeline is subject to change. Until then, no repairs are necessary for this specific condition.

For dealerships, the service procedure outlined in TSB 2066675/1 involves explaining the situation to the customer and creating a Pending Service Solutions (PSS) record. This record is logged in the PSS application via Access Audi or the Technical Assistance page in Elsa, allowing Audi to track affected vehicles and notify technicians when the final solution is released.
