Important Warnings for Owners and Technicians

Audi Technical Service Bulletin 43 24 84 2067283/4 contains crucial information for both vehicle owners and service technicians. If Diagnostic Trouble Code (DTC) U112100 is the only fault logged in the J775 suspension control unit (diagnostic address 0074), no repair work should be performed. Audi explicitly states that this DTC has no adverse effects on the suspension system.

Furthermore, this TSB is designated as informational only and is not applicable to any Audi Warranty claims. This means that any diagnostic time or unnecessary repairs performed solely for this code would not be covered under warranty.

Understanding the U112100 DTC

Diagnostic Trouble Code (DTC) U112100, labeled as a "Data bus missing message," is a fault code that may be stored in the J775 suspension control unit. This particular code is often accompanied by specific symptom codes such as 262222, 262256, and 262258. Unlike many DTCs that indicate a functional problem, the presence of Audi e-tron GT U112100 does not signify a malfunction that impacts vehicle operation or safety.

This code is typically discovered during routine diagnostic checks, such as pre-delivery inspection (PDI) for new vehicles or other diagnostic work performed by a technician. Owners are not expected to experience any noticeable symptoms or warnings on their dashboard related to this specific code.

What This Means for Your Audi e-tron GT

The most important takeaway from Audi TSB 43 24 84 2067283/4 is that the Audi e-tron GT U112100 DTC, when found in isolation within the J775 suspension control unit, is benign. It does not affect the performance, ride quality, or safety of your vehicle's suspension system. This TSB was issued to clarify this point for service personnel, preventing unnecessary diagnostic time and potential repairs for a non-issue.

If you own a 2022-2024 Audi e-tron GT or RS e-tron GT and a diagnostic scan reveals this specific DTC, you can be assured that it does not indicate a problem requiring attention. The vehicle's suspension system will continue to function as designed.

Next Steps for Owners

If your Audi e-tron GT has been diagnosed with the Audi e-tron GT U112100 DTC, and no other related fault codes or symptoms are present, there is no action required on your part. You do not need to seek a repair for this specific code. If a service center suggests repairs based solely on this DTC, you may reference Audi Technical Service Bulletin 43 24 84 2067283/4 to inform them of Audi's official stance that no repair is necessary.

This TSB supersedes an earlier bulletin, Group 43 number 24-79, dated January 4, 2024, indicating Audi's ongoing effort to provide clear guidance on this diagnostic code.
