2022-2024 Audi e-tron Charging Faults and Other Issues

Audi has released an on-car analysis list dated November 20, 2023, detailing various common issues affecting a wide range of its 2022-2024 models, including the Audi e-tron. This document serves as a guide for technicians to address customer complaints, from electrical malfunctions like an Audi e-tron charging fault to mechanical issues such as coolant leaks and engine noises.

Important Warnings for Owners and Technicians

Audi emphasizes that owners should contact the Audi Helpline before attempting any repair. For technicians, all topics discussed in this analysis list require associated worksheets to be filled out and attached to the TAC (Technical Assistance Center) ticket. These worksheets are crucial for proper diagnosis and can be found in Elsa2Go under Service References, by searching for "v4p."

Audi e-tron Charging Fault

One significant concern highlighted for 2019-2024 e-tron Q and e-tron SB models is the Audi e-tron charging fault. Owners may experience issues where the "Charging cable cannot be removed from the vehicle" or the "Vehicle cannot be charged, charge socket lock without function."

Diagnosis: If you encounter this Audi e-tron charging fault, technicians are instructed to consult the e-tron charging questionnaire worksheet for detailed diagnostic steps. This ensures a structured approach to identifying the root cause of the charging system malfunction.

Other Reported Issues Across Audi Models

The analysis list covers a broad spectrum of problems affecting various Audi models from 2022-2024. These issues are categorized below for clarity.

Engine and Powertrain Concerns

• Coolant System Issues:
  • Low Coolant Warning: For 2020-2021 Audi Q3 models, customers may report a "Coolant warning Lamp" despite the coolant level appearing full in the reservoir. Technicians should verify the reservoir level and note that this issue may not relate to TSB 2061918.
  • Coolant Leaks: A "Coolant leak from expansion tank" is noted for 2023 Audi A4 models, requiring photo documentation of the leak source. Additionally, "Coolant pump leaking" is a concern for 2021-2024 SQ5, Q7, Q8, S6, S7, S4, S5, RS5, and A8 models with 3.0L and 2.9L engines, necessitating photo and video documentation.
  • Broken Coolant Reservoir Cap: 2021-2023 Audi Q5 models may experience a "coolant reservoir cap broken," which typically requires replacement of the tank and cap.
• Catalytic Converter and Fuel Pressure:
  • Catalytic Converter Efficiency: 2019-2023 A6, A7, Q7, Q8, S4, S5 models with 3.0L engines may exhibit a "Check engine lamp is on, DTC P042000: Catalyst System, Bank1 Efficiency Below." Diagnosis involves GFF logs, fault codes, test plans, and potentially oil and fuel samples.
  • Low Fuel Pressure: 2019-2023 Audi Q3 models may experience "P008700 Low fuel pressure." This applies specifically to Q3 models within NVLW (New Vehicle Limited Warranty) and requires a completed worksheet on initial TAC contact.
• Engine Sound Generator Malfunction: 2021-2023 models with 3.0L EA839 engines may have "Abnormal/no sound from engine sound generator." Diagnosis includes video/sound recordings of the noise and sound actuator test, along with GFF logs and relevant DTCs.
• Belt Tensioner Damper Noise: For 2020-2024 A6, A7, Q7, Q8, S4, S5 models with EA839 3.0L and 2.9L engines, "noise from belt tensioner damper" may occur, specifically related to part number 06M903133AA. This issue is only applicable if no prior repairs to the starter generator/belt drive system have been performed.

Electrical and Sensor Problems

• Wheel Speed Sensor Faults: 2023-2024 Audi A3 models may report a "Wheel speed sensor Magnetic field too low," accompanied by DTCs C101AF1, C101BF1, C101CF1, and C101DF1. Specific cases are needed for these DTCs.
• Front Side Window Inoperative: 2022-2024 Audi e-tron GT models may experience a "Front side window inoperative." Technicians should investigate if a front door module function is inoperative, performing a water test and inspecting the door harness and pillar connection.
• Air Suspension Warning: For 2018-2024 Audi SQ5 models, an "Air suspension warning" with DTC P089200 may indicate a "Wire broke at air compressor V66." A broken, damaged, or loose connection at V66 (Suspension Compressor) T3DL is often the cause.

Interior Noise Concerns

• Front Door Trim Panel Noise: 2023-2024 e-tron Quattro and e-tron SB models may exhibit "Noise from Front Door Trim Panel while driving." Diagnosis involves video recording of the noise before repair and photos of the repair.
• Front Door Speaker Grill Noise: 2023-2024 Audi A5 models may also have "Noise from Front Door speaker Grill while driving," requiring similar video and photo documentation.

General Diagnosis and Repair Advice

For all these issues, the common thread is the requirement for thorough documentation and adherence to Audi's diagnostic procedures. Technicians are consistently directed to fill out specific worksheets, upload GFF logs, and provide photo/video evidence where applicable. This ensures that complex issues are properly analyzed and resolved, maintaining vehicle safety and performance.
