Symptoms
Owners of affected 2021-2023 Audi A5, S5, and RS 5 models may experience an illuminated Malfunction Indicator Lamp (MIL), commonly known as the engine warning light. This condition is often accompanied by specific diagnostic trouble codes (DTCs) stored in the vehicle's engine control module.
Fault Codes / DTCs
The following diagnostic trouble codes (DTCs) may be stored intermittently or statically in the engine control module (ECM), identified as J623 (address word 0001), when the Audi A5 engine warning light is active:
| Code | Description |
|---|---|
| P013E00 | O2 Sensor Bank 1 Sensor 2 Delayed Response - Rich to Lean |
| P013F00 | O2 Sensor Bank 1 Sensor 2 Delayed Response - Lean to Rich |
| P014A00 | O2 Sensor Bank 2 Sensor 2 Delayed Response - Rich to Lean |
| P014B00 | O2 Sensor Bank 2 Sensor 2 Delayed Response - Lean to Rich |
Technical Background
Audi has identified that these DTCs are stored without a legitimate reason. The root cause is a software issue within the engine control module related to the oxygen sensor diagnosis on new catalytic converter systems. This means the oxygen sensors themselves are not necessarily faulty, but the vehicle's software is misinterpreting their readings.
Important Warnings
Owners should be aware of the following critical information regarding this Technical Service Bulletin 01 22 17 2066257/1:
- This TSB only applies to vehicles with a mileage of less than 3,000 miles.
- If your vehicle is outside of any applicable warranty, this Technical Service Bulletin is informational only, and any repair costs may not be covered.
Repair Procedure Summary
The resolution for the Audi A5 engine warning light and associated DTCs involves a software update to the engine control module (ECM) J623. Technicians must first follow the instructions detailed in TSB 2011732, which covers Software Version Management (SVM) operating procedures. Subsequently, the ECM is updated using the specific SVM action code 01A264, along with the new software part numbers 8W0.907.551.D (for RS5 Coupe) or 8W0.907.551.G (for RS5 Sportback), both to version 0004 or higher. This update corrects the software logic for oxygen sensor diagnosis.
Required Tools
To perform the software update, technicians will need a VAS tester, specifically models VAS 6160 or VAS 6150, equipped with the current version of ODIS (Offboard Diagnostic Information System) running on Windows 10.
Warranty Information
This repair is covered under warranty for up to 48 months or 50,000 miles, whichever comes first, under Claim Type 110. For Certified Pre-Owned (CPO) vehicles, Claim Type G10 applies, requiring verification of owner status. The Service Number is 2470, and the Damage Code is 0039. Labor operations for the software update, including DTC checking, are assigned code 0151 0000, with a maximum allowance of 50 time units (TU). Diagnostic time and road tests before and after the procedure are included in the software update and have no additional allowance.
