This communication, identified by NHTSA ID 11009251, serves as a guide for technicians and highlights several distinct problems that owners might experience.

Important Warnings for Owners and Technicians

Audi advises all personnel to "Please contact Audi Helpline before attempting repair" for any of the issues outlined in this list. Additionally, a significant change in diagnostic procedures is noted: "As of 6/7/2024 worksheets will no longer be used as a stadard practice. Worksheets will only be required if listed in the topic details."

Common Technical Issues Overview

This analysis list covers a range of problems from engine-related diagnostic trouble codes (DTCs) to infotainment system glitches and inoperative controls. Each issue is detailed with its associated models, model years, and initial diagnostic or action steps.

Gas Cap Seal Deformed (DTC P045600)

Owners of certain Audi A4, A5, and Q5 models from 2023-2024 may encounter a diagnostic trouble code P045600, indicating a "very small Leak" in the evaporative emissions system. This often points to a deformed gas cap seal. If you experience an "Audi P045600 gas cap" issue, the recommended action is to check the gas cap to see if its seal is visibly deformed. Technicians are instructed to open a Technical Assistance Center (TAC) case and provide the requested information for further guidance.

O2 Sensor P013B00 Fault

For 2023-2024 Audi A5 and Q5 vehicles, a common issue involves the O2 sensor, specifically DTC P013B00. This code signifies a "Sensor Bank1-Sensor2 Slow Response - Lean to Rich" condition. Before any repair work, it is crucial to verify the presence of DTC P013B00. Technicians are advised to contact the TAC for further instructions, as an onsite repair might be necessary.

MIB3 Infotainment Stuck on Loading User Information

2024 Audi A3 and Q3 owners might experience their MIB3 infotainment system getting stuck during startup. The primary symptom is the screen being stuck at the "loading user information" screen during bootup, with no user interaction possible during this time. Notably, the backup camera typically works normally despite this issue. If these criteria are met, technicians should contact the TAC for potential data logger installation to diagnose the problem further.

Inoperative Roof Panel Buttons

Owners of 2022-2024 Audi Q4 e-tron models may find their roof panel buttons inoperative. This can manifest as "Dome light buttons unresponsive or come on with no input" and "Sunroof buttons are unresponsive (typically in addition to dome light)." For this specific issue, the analysis list directs technicians to "See worksheet for instructions," indicating that a more detailed repair procedure is available in a separate document.
