2022-2026 Audi e-tron GT ABS/ESC Warning Lamp DTCs

Important Information for Owners

Audi has released Technical Service Bulletin (TSB) 2064758/4 to address specific diagnostic trouble codes (DTCs) that may be found in the ABS control module (J104) of 2022-2026 Audi e-tron GT and RS e-tron GT vehicles. This bulletin clarifies that while these codes may appear during diagnostic scans, they are a result of normal control module communication and do not indicate a fault or require any repair. The function of the ABS/ESC system is not affected or restricted by the presence of these DTCs.

This TSB, identified as 2064758/4, supersedes previous bulletin Group 45 number 22-28 dated November 2, 2022. It is purely informational and is not applicable to any Audi Warranty claims, as no service action is necessary.

Symptoms

Owners of affected 2022-2026 Audi e-tron GT vehicles typically will not experience any noticeable symptoms or customer concerns related to these codes. The diagnostic trouble codes (DTCs) are usually discovered during a Pre-Delivery Inspection (PDI) or other diagnostic work performed by a technician. In some cases, the ABS/ESC warning lamp may flash in the instrument cluster when a diagnostic tester is connected to the vehicle.

Fault Codes / DTCs

During diagnostic inspections, the following DTCs may be found stored in the ABS control module, J104 (address word 0003):

Code	Description	Symptom Code(s)
B2F0100	Development code 1	358656 (static), 339457 (intermittent)
U012700	Tire Pressure Monitoring Control Module - no Communication	358656 (static)
U112200	Data bus implausible message	303616 (static)
U112300	Data bus error value received	169984 (intermittent), 303360 (static)

Diagnosis / Trigger Conditions

These diagnostic trouble codes (DTCs) are typically identified during routine diagnostic scans, such as those performed during a Pre-Delivery Inspection (PDI) or other workshop diagnostic procedures. The TSB specifies that the ABS/ESC warning lamp might flash in the instrument cluster specifically when a diagnostic tester is connected. The presence of these codes, including the Audi e-tron GT ABS DTCs, is considered normal behavior for the control module's communication system.

What Owners Should Know

It is crucial for owners to understand that the presence of DTCs B2F0100, U012700, U112200, and U112300 in their 2022-2026 Audi e-tron GT does not signify a problem with their vehicle. Audi has explicitly stated that these codes are logged for design reasons related to control module communication and do not cause any issues for the customer. The functionality of the ABS/ESC system remains completely unaltered and unrestricted. Therefore, no repair or service measure is necessary to address these specific Audi e-tron GT ABS DTCs.

Furthermore, the TSB notes that while intermittent DTCs can be erased, they will reappear as soon as the conditions that trigger them occur again. Static DTCs, by their nature, cannot be erased. This reinforces that these codes are an inherent part of the vehicle's system operation and not an indication of a defect.

Manufacturer's Stance

Audi's Technical Service Bulletin 2064758/4 serves as an informational document for technicians. It clarifies that these specific DTCs are expected and do not warrant any action or repair. This means that if these codes are found during a diagnostic check, no parts replacement, software update, or other service procedure is required. This TSB is not associated with any warranty claims, as it addresses a non-issue.
