2021-2026 Audi e-tron: Delayed DC Charging Start TSB

Audi has issued Technical Service Bulletin (TSB) 93 24 73 2074616/1 to address customer inquiries regarding a perceived issue with Audi e-tron delayed DC charging. This bulletin clarifies that a delay in the start of direct current (DC) charging is a normal operational characteristic of these vehicles, not a fault. The information provided aims to inform owners and technicians that such delays are expected and do not indicate a malfunction.

Symptoms

Owners of affected Audi e-tron models may notice that DC charging sometimes starts too slowly. The time taken for DC charging to start varies, leading to concerns about the charging system's functionality. This perceived Audi e-tron delayed DC charging is the primary symptom reported by customers.

Why This Happens

The TSB explains that when performing DC charging, especially at high power levels, it is normal for 30 to 90 seconds to elapse between connecting the charging connector and the start of energy flow. This initialization period can sometimes extend to over one minute. The delay is due to essential communication between the vehicle and the charging station, which includes necessary safety checks like insulation measurement, ensuring a secure and efficient charging process.

Important Information for Owners

Audi emphasizes that customers should be informed that the initialization process time can vary based on the charging station manufacturer and the selected charging power. Higher charging power generally leads to a longer initialization period. Additionally, vehicles with a low state of charge might experience slightly longer delays.

Crucially, Audi states: "Please inform the customer that the time taken for this initialization process may vary depending on the charging station manufacturer. The selected charging power also has an influence on this. The general rule: The higher the charging power is, the longer the initialization process will take. The initialization process may also take slightly longer for vehicles with a low state of charge. Depending on the charging station manufacturer, the initialization process may take as long as over one minute. This is neither a malfunction nor a fault on the vehicle or charging station."

No Fault Codes or Repair Needed

Workshop findings indicate that no relevant diagnostic trouble codes (DTCs) are logged when this condition occurs. This further supports the conclusion that the Audi e-tron delayed DC charging is not a fault. Since this is considered normal operation, there is no production solution or specific service procedure required to address this characteristic. The TSB 93 24 73 2074616/1 is informational only and does not apply to any Audi Warranty claims.
