Symptoms

Owners of 2022-2023 Audi Q3, Q5, and Q7 vehicles may experience the Malfunction Indicator Lamp (MIL) illuminated on their dashboard. This is the primary symptom associated with the condition described in Technical Service Bulletin 2071770/9.

Fault Codes / DTCs

When the MIL is illuminated, a diagnostic scan of the Engine Control Module (-J623-, address word 0001) will reveal the following Diagnostic Trouble Code:

  • P2407 (P240700): "EVAP emission control system leakage diagnosis pump current fluctuating"

No other relevant event memory entries are typically logged in the engine control unit for this specific issue.

Important Warnings for High-Voltage Vehicles

For Audi Q5 PHEV models, which include high-voltage components, a critical step must be followed during the software update. To prevent potential damage to the high-voltage components, the high-voltage cable must be removed before the SVM (Software Version Management) code is entered. Charging the high-voltage battery during a software update can cause damage.

Diagnosis

The root cause of the illuminated MIL and the "Audi Q7 P240700 MIL on" condition is identified as overly sensitive On-Board Diagnostics (OBD) for the EVAP system. This sensitivity leads to the erroneous detection of a "leakage diagnosis pump current fluctuating" fault, even when no actual mechanical issue is present in the EVAP system.

Repair Procedure Summary

The permanent solution for this condition involves updating the software in the Engine Control Module (-J623-, address word 0001). This new software addresses the overly sensitive OBD diagnostics, preventing the false triggering of the P240700 DTC. The repair procedure requires following the instructions in TSB 2011732, which covers Software Version Management (SVM) operating procedures. The SVM action code 01A320 is used to perform the update.

Specific software part numbers and versions are updated depending on the model and model year:

  • Q7 2.0I MY2023: Old software part number 4M0.906.259.AB (versions 0002, 0003, 0004) is updated to new software part number 4M0.906.259.AB (version 0005).
  • Q7 2.0I MY2022: Old software part number 4M0.906.259.AE (version 0001) is updated to new software part number 4M0.906.259.AE (version 0002).
  • Q3 MY2022: Old software part number 83A.906.259.D (version 0001) is updated to new software part number 83A.906.259.D (version 0002).
  • Q3 MY2023: Old software part number 83A.906.259.F (version 0001) is updated to new software part number 83A.906.259.F (version 0002).
  • Q5 MY2022: Old software part number 80A.906.259.AB (version 0002) is updated to new software part number 80A.906.259.AB (version 0003).
  • Q5 PHEV MY2022: Old software part number 80A.906.259.AA (version 0001) is updated to new software part number 80A.906.259.AA (version 0002).
  • Q5 MY2023: Old software part number 80A.906.259.AE (versions 0002, 0003) is updated to new software part number 80A.906.259.AE (version 0004).
  • Q5 PHEV MY2023: Old software part number 80A.906.259.AD (version 0001) is updated to new software part number 80A.906.259.AD (version 0002).

Required Tools

To perform the software update, technicians will need a VAS tester with the current version of ODIS (Windows 10), specifically models VAS 6160 or VAS 6150.

Frequently Asked Questions

What does the DTC P240700 'EVAP emission control system leakage diagnosis pump current fluctuating' mean?
This diagnostic trouble code indicates that the vehicle's Engine Control Module has detected an anomaly in the current readings from the EVAP (Evaporative Emission Control System) leakage diagnosis pump. In the case of Audi models covered by TSB 2071770/9, this is often a false alarm caused by overly sensitive diagnostic software rather than a physical leak.
Which Audi models and years are affected by the P240700 MIL on issue?
This issue primarily affects 2022-2023 Audi Q3, Q5, and Q7 models, including Q5 PHEV variants. The specific software update required varies by model and model year.
How is the 'MIL on' with DTC P240700 resolved for these Audi vehicles?
The resolution involves a software update to the Engine Control Module (-J623-) using the SVM action code 01A320. This update recalibrates the OBD diagnostics to prevent the false triggering of the P240700 fault code.
Is there anything special to know for Audi Q5 PHEV owners regarding this repair?
Yes, for Q5 PHEV models, it is crucial that the high-voltage cable is removed before the SVM code is entered during the software update. This prevents potential damage to the high-voltage components from unintended battery charging during the process.
