2021-2024 Audi Coolant Leak from Coolant Pump TSB 2071515/1

Audi has released Technical Service Bulletin (TSB) 2071515/1 to address instances of coolant leaks originating from the coolant pump in various 2021-2024 models equipped with the 2.0L TFSI engine. This bulletin provides guidance for technicians on accurately diagnosing and resolving an Audi 2.0 TFSI coolant leak.

Symptoms of an Audi 2.0 TFSI Coolant Leak

Owners of affected Audi vehicles may experience one or more of the following issues:

• The customer notes "coolant loss", or a visible "coolant leak".
• The "coolant warning lamp is illuminated" on the dashboard.

Workshop findings indicate that these symptoms are typically traceable to a leak originating from the coolant pump.

Diagnosis and Trigger Conditions

To accurately diagnose an Audi 2.0 TFSI coolant leak and ensure proper repair, technicians are instructed to follow a specific procedure. This involves first taking a clear photo of the leak, including the VIN and date, and uploading it to the DOC-IT system. The photo should be in focus, well-lit, and, if possible, mark the exact location of the problem without showing personal information like faces or license plates.

After documentation, the area around the leak and any traces of coolant must be thoroughly cleaned and dried. The cooling system is then filled to its maximum level. The vehicle should be driven for a few miles to allow the system to pressurize and the leak to potentially reappear. If no further coolant leak is detected after this reassessment, no parts should be replaced, and the vehicle should continue to be observed. However, if a coolant leak is detected again, the component causing the damage, typically the coolant pump, should be replaced.

Important Warnings for Owners

Audi emphasizes that repairs related to TSB 2071515/1 must only be carried out if all specified criteria, including model/type, chassis number, engine/motor code, PR numbers, part numbers, and software versions, precisely match the vehicle. Failure to adhere to these criteria may result in the problem not being resolved, necessitating repeat repairs, and potentially leading to the rejection of warranty claims and re-debiting of parts.

Repair Procedure Summary

The repair process for an Audi 2.0 TFSI coolant leak involves several key steps:

1. Documentation: Before any repair, a photograph of the leak must be taken and uploaded to DOC-IT. This photo needs to clearly show the VIN and date, be in focus, and indicate the precise location of the leak without capturing any personal data.
2. Preparation: The area around the leak and any coolant traces must be thoroughly cleaned and dried.
3. System Fill: The cooling system is then filled to its maximum capacity.
4. Reassessment: After driving the vehicle for a few miles, the suspected leak area is reassessed. If no further leak is observed, no parts are replaced, and the vehicle is monitored.
5. Component Replacement: If the leak reappears, the component identified as the source of the leak, which is typically the coolant pump, is replaced.
