2021-2022 Audi e-tron Twisted Seatbelts and Other Technical Issues

Audi has issued a comprehensive Vin-4-Pin Topic List to guide its technicians on diagnosing and reporting various technical issues across several models. This document serves as a critical reference, outlining specific symptoms, affected vehicles, and the precise information required when submitting cases to the Technical Assistance Center (TAC). It ensures that all necessary diagnostic data and evidence are collected upfront, streamlining the repair process for complex concerns like Audi e-tron twisted seatbelts.

This list is dynamic, with information frequently updated, underscoring the importance of using the latest version available through Audi's internal service portals.

Detailed Overview of Common Audi Issues

The Vin-4-Pin Topic List addresses a range of distinct issues that owners might encounter. Understanding these can help you describe symptoms accurately to your service center.

Coolant Warning Lamp Concerns

For 2020-2021 Audi Q3 models, owners might see a low coolant warning lamp illuminate in the instrument cluster, even when the coolant reservoir appears to be full. Technicians are instructed to check if the case relates to TSB 2061918 and provide photos of the reservoir level, along with the complete reservoir, connector, and a 4-inch harness section.

Active Air Shutter Malfunctions (DTC P05A000)

Owners of 2021-2022 Audi Q7 and Q8 vehicles may experience an illuminated check engine lamp with Diagnostic Trouble Code (DTC) P05A000 stored in the Engine Control Module (ECM). This DTC indicates that the "Active Grille Air Shutter 'A' Stuck." For diagnosis, technicians need to confirm the P05A000 code and provide photos of the shutter motor.

PDC Sensor Connector Problems (DTC B107B13)

Certain 2022 Audi Q3 and A6 models can suffer from loose PDC (Park Distance Control) sensor connectors. Specifically, 2022 Q3s may have a loose rear PDC sensor connector, while 2022 A6s can have loose connectors at either the front or rear bumper. This issue can lead to DTC B107B13, indicating a "Rear parking aid sensor Open circuit." Technicians are required to provide photos of the sensor connector as found and the bumper harness label, and ideally, the vehicle should be untouched prior to bumper removal for initial inspection.

Audi e-tron Twisted Seatbelts

In 2021-2022 Audi A6, A7, A8, Q8, e-tron Quattro, and e-tron Sportback models, front seatbelts have been observed to become twisted. If you own a 2021-2022 Audi e-tron and notice twisted seatbelts, your dealer will need to submit specific photographic evidence. This includes a photo of the twisted seatbelt showing both the B-pillar and seat bottom in the same frame, as well as a photo of the seatbelt deflector trim at the shoulder height adjustment.

Noise from Speaker Grills and Door Trim Panels

Owners of 2021-2022 Audi A5, e-tron quattro, and e-tron Sportback quattro models might report noise emanating from the front door loudspeaker grille or the front door trim panel, especially during music playback or while driving. Technicians are required to submit video of the noise before repair, photos of the repair, and photos of the sound settings in the MMI and the music genre/song being played.

ACC Sensor Misadjustment (DTC C110300)

For 2022 Audi Q5 vehicles, an ACC (Adaptive Cruise Control) warning may appear shortly after Pre-Delivery Inspection (PDI). This can be associated with DTC C110300, indicating a "Sensor misadjusted in DA 0013." A key condition for this diagnosis is that the vehicle must have less than 600 miles. Technicians are asked to provide photos of the bumper mold number as part of the information needed.
