2022-2024 Audi e-tron GT U112100 Suspension DTC TSB

Important Warning for Audi Owners

Audi has issued Technical Service Bulletin 2067283/2 to address a specific diagnostic trouble code (DTC) that may appear in the J775 suspension control unit of certain e-tron GT and RS e-tron GT models. This bulletin contains a crucial instruction: "If only the DTCs described above are logged in address 0074, do not perform any repair work." This means that if your vehicle exhibits only the U112100 DTC with its associated symptom codes, there is no need for a repair, and attempting one will not resolve any underlying issue. Furthermore, Audi explicitly states that these DTCs have "no effects on the suspension system."

What's Being Addressed

This Technical Service Bulletin, identified as 43 23 71 2067283/2, concerns the presence of diagnostic trouble code U112100 within the J775 suspension control unit. This issue primarily affects 2022-2024 Audi e-tron GT and RS e-tron GT vehicles. The TSB was revised on May 19, 2023, to include additional model years, superseding a previous bulletin, Group 43 number 22-61, dated June 9, 2022.

Symptoms

Owners of affected vehicles typically do not experience any noticeable symptoms or performance issues related to this DTC. The presence of the U112100 fault code is usually discovered during routine diagnostic checks, such as a Pre-Delivery Inspection (PDI) for new vehicles, or during other diagnostic work performed by a technician. There are no customer concerns reported in relation to this specific issue.

Fault Codes / DTCs

The following diagnostic trouble code (DTC) and associated symptom codes may be logged in the J775 suspension control unit (diagnostic address 0074):

• U112100: Data bus missing message_ (active/static symptom code 262222)
• U112100: Data bus missing message_ (active/static symptom code 262256)
• U112100: Data bus missing message_ (active/static symptom code 262258)

These codes indicate a "Data bus missing message" condition, but as clarified by Audi, they do not signify a functional problem with the suspension system itself.

Diagnosis and Trigger Conditions

The U112100 DTC is typically identified through workshop findings rather than customer complaints. Technicians will find these codes logged in the J775 suspension control unit, specifically at diagnostic address 0074, during routine vehicle inspections or when performing other diagnostic procedures. The TSB emphasizes that the presence of this particular Audi e-tron GT U112100 fault does not indicate a need for repair.

What Owners Should Know

For owners of 2022-2024 Audi e-tron GT and RS e-tron GT models, it is important to understand that the U112100 diagnostic trouble code, when found in the J775 suspension control unit with the specified symptom codes (262222, 262256, 262258), is considered benign. Audi's official guidance via TSB 2067283/2 is to not perform any repair work if these are the only DTCs present. This means you should not be charged for diagnosis or repair of this specific code, as it has no functional impact on your vehicle's suspension system. This TSB is informational and does not fall under warranty for repair work.
