2021-2025 Audi Air Suspension Malfunction Warning TSB

Owners of various 2021-2025 Audi models equipped with air suspension may encounter an "Air suspension malfunction warning in the instrument cluster." This warning is often accompanied by specific diagnostic trouble codes (DTCs) related to the air suspension system. This issue is addressed by Audi Technical Service Bulletin 2059363/6, which supersedes previous bulletin 24-85 dated April 5, 2024.

Symptoms

The primary symptom of this issue is an "Air suspension malfunction warning in the instrument cluster." This warning indicates a problem with the vehicle's air suspension system, potentially affecting ride comfort, vehicle leveling, or handling. If you experience an Audi e-tron air suspension malfunction, it is important to have your vehicle diagnosed.

Fault Codes / DTCs

When an Audi e-tron air suspension malfunction occurs, technicians will typically find one of the following diagnostic trouble codes (DTCs) stored in the suspension control module, J775 (address word 0074):

Code	Description	Symptom Code
C1260F0	Compressor control unit for adaptive suspension, no communication	262400
U112100	Data bus, missing message	262400

Diagnosis and Repair Procedure

To address the Audi e-tron air suspension malfunction, technicians should first inspect the wiring and connector contacts between the suspension control module (J775) and the compressor control module (J1135). If no issues are found with the connections, the next steps depend on the nature of the stored DTC:

• Passive/Sporadic DTC: If the DTC is passive or sporadic, it should be deleted, and the vehicle can be released.
• Active/Static DTC: If the DTC is active or static, the compressor control unit J1135 must be replaced. This replacement should follow the procedures outlined in the Elsa Repair Manual, specifically under Chassis >> Suspension, Wheels, Steering >> 43 Self Levelling Suspension >> Air Suspension >> Level Control System Compressor Electronics J1135, Removing and Installing.

This procedure, detailed in TSB 2059363/6, ensures that the root cause of the air suspension malfunction is properly identified and corrected.

Important Warnings

Owners and technicians should be aware of a critical detail regarding this repair. If the DTC C1260F0 (262400) or DTC U112100 (262400) are stored for a second time in the suspension control unit J775 as passive/sporadic, it is mandatory to replace the compressor control unit J1135. This indicates a persistent issue that clearing the code alone will not resolve.

Required Parts and Tools

For repairs involving the replacement of the compressor control unit, the following parts may be required:

• Level Control System Compressor Electronics J1135: Quantity 01 (Part number to be determined via ETKA)
• Fasteners, Bolts, Nuts, and Screws: As needed per the Repair Manual (Part numbers to be determined via ETKA/ELSA)

Warranty Information

Warranty claims for this issue are typically covered for up to 48 months or 50,000 miles. For Certified Pre-Owned (CPO) vehicles, G10 coverage applies, subject to owner verification. If the vehicle is outside of its warranty period, this Technical Service Bulletin serves as informational guidance only, and repair costs may not be covered.
