2022 Audi e-tron GT / RS e-tron GT DTC P1D6C00

Important Warning for Owners

Audi Technical Service Bulletin 2064846/1 issues a critical advisory for owners of 2022 Audi e-tron GT and RS e-tron GT models. It explicitly states: "The DTC does not affect the operation of the vehicle and no action is required. Please do not attempt any repairs." This means that no diagnostic or repair work should be performed for this specific fault code, as it will not resolve any underlying issue and is not necessary for the vehicle's proper function or safety.

Symptoms and Diagnosis

For 2022 Audi e-tron GT and RS e-tron GT models, the only symptom associated with this issue is the presence of Diagnostic Trouble Code (DTC) P1D6C00. This code is stored in the gateway control unit, identified as J533 (address word 0019), and is described as "12V battery faulty." The TSB notes that this DTC typically appears as a sporadic or intermittent fault. Importantly, Audi confirms that customers generally do not report any concerns related to this specific DTC. Instead, it is usually discovered during routine diagnostic checks, such as pre-delivery inspection (PDI) or other workshop activities, rather than being triggered by a noticeable vehicle malfunction.

Technical Background

According to Audi's technical analysis, the presence of DTC P1D6C00, labeled as "12V battery faulty," is not indicative of an actual fault with the 12V battery or the vehicle's electrical system. Instead, it is attributed to a software error within the J533 gateway control unit. This software anomaly causes the diagnostic system to incorrectly log the P1D6C00 code. Despite its appearance, this software error does not impact the operational integrity, performance, or safety of the vehicle. It is a benign diagnostic entry that does not reflect a functional defect.

Service Guidance: No Repair Required

Audi Technical Service Bulletin 2064846/1 provides clear guidance regarding this specific issue. Under the 'Production Solution' section, it states "Not applicable," indicating that no manufacturing change or fix is required. Furthermore, the 'Service' section explicitly advises: "The DTC does not affect the operation of the vehicle and no action is required. Please do not attempt any repairs." This directive emphasizes that technicians should not perform any diagnostic or repair procedures solely based on the presence of the Audi e-tron GT DTC P1D6C00. Attempting repairs would be unnecessary and would not resolve the software-related diagnostic entry.

What Owners Should Do

If you own a 2022 Audi e-tron GT or RS e-tron GT and a diagnostic scan reveals the Audi e-tron GT DTC P1D6C00, no specific action is required on your part. Based on Audi's official guidance in TSB 2064846/1, this is a known software error that does not affect vehicle operation. Therefore, you do not need to schedule a service appointment, nor should you authorize any repairs specifically aimed at addressing this diagnostic code. Owners can continue to operate their vehicles normally, as this DTC does not indicate a functional problem.

Warranty Information

Technical Service Bulletin 2064846/1 is issued purely for informational purposes. Audi explicitly states that this bulletin and the condition it describes are "not applicable to any Audi Warranty." This means that any diagnostic or repair attempts related to DTC P1D6C00 would not be covered under warranty, as the manufacturer has deemed it a non-issue that does not require intervention.
