2021-2023 Audi e-tron Electric Motor Condensation TSB

Understanding Audi e-tron Electric Motor Condensation

Audi has issued Technical Service Bulletin (TSB) 93 25 47 2070348/2 to address observations of condensation inside the cover for power electronics connections in the electric drive motor. This bulletin, dated January 9, 2025, supersedes an earlier TSB, Group 93 number 23-07, from May 16, 2023.

The TSB aims to provide guidance to technicians regarding this specific condition, ensuring proper diagnosis and preventing unnecessary repairs. For 2021-2023 Audi e-tron and e-tron Sportback models, understanding this TSB can help owners comprehend potential observations related to the electric drive motor.

What Owners Might Notice

While there may not be specific dashboard warning lights, owners might experience various general concerns that lead a technician to inspect the electric drive motor. During workshop inspections, technicians may find visible condensation on the inside of the cover for power electronics connections in the electric drive motor. This Audi e-tron electric motor condensation is the primary condition addressed by this TSB.

Technical Explanation

According to Audi, the presence of condensation in this area is a result of natural temperature differences and humidity. The technical background provided in the TSB states that if the concern is solely condensation, it will not lead to further issues or impact the vehicle's performance. This means that, in most cases, this condensation is considered a normal occurrence.

Important Service Advisory: What Not to Do

This TSB includes a crucial instruction for technicians: Do not perform additional repairs if water condensation is detected on the inside of the cover for power electronics connection to the motor. This guidance is vital to prevent unnecessary service work.

However, the TSB emphasizes the importance of a thorough check for coolant. Technicians must verify that there is no coolant present in the area around the bolts or within the connection area. If coolant is detected, this TSB does not apply, and the condition requires further diagnosis and appropriate repair, as a coolant leak would indicate a different, more serious issue than simple Audi e-tron electric motor condensation.

TSB Details and Revisions

This Technical Service Bulletin is identified as 93 25 47 2070348/2. It is the second revision, with the initial publication occurring on May 17, 2023. The latest revision, dated January 9, 2025, primarily involved a revised header to include additional model years. This bulletin supersedes the previous TSB Group 93 number 23-07, which was issued on May 16, 2023.

Warranty Coverage

Audi states that this TSB is informational only and does not apply to any Audi Warranty. This means that while it provides important diagnostic and repair guidance, it does not outline a specific warranty repair or recall action for the condensation condition itself.
