This TSB, which supersedes previous bulletin 24-84, provides crucial guidance for technicians and owners regarding this specific fault code.

The TSB clarifies that while the DTC U112100 may appear, it does not indicate a functional problem with the vehicle's suspension system.

For the Audi e-tron GT U112100 fault, Audi has determined that no repair is necessary.

Symptoms

Owners of affected vehicles will typically experience no noticeable symptoms related to this DTC. The TSB explicitly states, "No customer concerns," indicating that the presence of the U112100 code does not lead to any observable issues or changes in the vehicle's performance or handling. The suspension system continues to function as intended.

Fault Codes / DTCs

The specific diagnostic trouble code addressed by TSB 43 24 95 2067283/5 is U112100, which is logged in the J775 suspension control unit (diagnostic address 0074). This DTC is associated with a "Data bus missing message" and can appear with various symptom codes:
