2021-2026 Audi e-tron Charge Connector Lock Malfunction TSB

Audi has issued Technical Service Bulletin (TSB) 2071328/1 to address an Audi e-tron charge connector fault that can prevent vehicles from charging. This issue specifically relates to the charge connector lock mechanism, which may fail to lock or unlock the charging cable.

Symptoms

Owners experiencing this Audi e-tron charge connector fault may notice the following:

• "The vehicle cannot be charged."
• "The charging cycle does not start."
• "The charging cable is not locked/unlocked by locking pin."

Workshop findings often confirm one or more of these customer statements.

Fault Codes / DTCs

When this issue occurs, one or both of the following Diagnostic Trouble Codes (DTCs) may be stored in the Control Module for high-voltage charging (-J1050-, address word 00C6):

Code	Description	Module
P33E800	Charge socket A, charge connector lock, mechanical malfunction.	High-voltage charging control module
P33E900	Charge socket B, charge connector lock, mechanical malfunction.	High-voltage charging control module

For vehicle models equipped with two charging sockets, DTC P33E900 may also be logged, depending on which charging socket is affected. Technicians often observe a relatively high frequency counter for these logged DTCs.

Diagnosis / Trigger Conditions

This Audi e-tron charge connector fault occurs when the locking pin on the charging socket is unable to fully enter its recess in the charging connector, despite multiple attempts during both AC and DC charging. Several factors can contribute to this problem:

• Heavy DC charging cables: The weight of particularly heavy DC charging cables can pull the connector downwards, preventing proper engagement.
• Cable tension: Tension on the charging cable, possibly due to an unfavorable parking position, can misalign the connector.
• Worn charging connector: Repeated use, especially at frequently used charging stations, can lead to wear on the connector.
• Improper insertion: The charging connector may not be plugged in correctly or inserted far enough into the charging socket.

Repair Procedure Summary

Audi's recommended solution for this Audi e-tron charge connector fault is a simple adjustment during the charging process. Technicians are instructed to inform customers that:

1. After plugging in the charging connector, gently lift it slightly.
2. Continue to lift the connector until it locks into place.

This action helps to prevent the connector from dropping and ensures the locking pin properly engages. In quiet environments, it may be possible to hear the pin locking into the charging socket.

Important Warnings

This Technical Service Bulletin (TSB) is for informational purposes only and is not applicable to any Audi Warranty. Owners should be aware that any diagnosis or repair related to this issue might not be covered under standard warranty terms.

Owner Action

If you are experiencing an Audi e-tron charge connector fault where your charging cable is not locking or unlocking, try the recommended procedure:

1. Plug in your charging cable as usual.
2. Immediately after plugging it in, gently lift the charging connector slightly until you feel or hear it lock into place.

If this simple adjustment does not resolve the issue, or if you continue to experience problems with charging, it is advisable to contact an authorized Audi service center for further diagnosis.
