2021-2023 Audi Oil Leak Detection TSB 2060750/3

Owners of 2021-2023 Audi vehicles experiencing symptoms of an oil leak may benefit from the diagnostic procedure outlined in Technical Service Bulletin (TSB) 2060750/3. This bulletin, issued on March 3, 2022, provides guidance for using a fluorescent UV additive to precisely identify the origin of engine oil leaks.

This TSB supersedes an earlier bulletin, Group 17 number 21-12, dated February 2, 2021, with updates including revised service steps and expanded vehicle data to cover newer model years.

Symptoms of an Audi Oil Leak

Audi owners might notice several indicators pointing to an engine oil leak. These observations are crucial for technicians to begin the diagnostic process. Common customer complaints include:

• "There may be a smell in the engine compartment."
• "An oil leak is present in the front end of the car or in the area of the engine compartment."
• "Oil marks may be found under the car."
• "There is engine oil loss."

Upon inspection, technicians often confirm these concerns with a finding that "An oil leak can be found in the engine area."

Understanding the Audi Oil Leak Detection Process

To accurately pinpoint the source of an engine oil leak, Audi technicians utilize a fluorescent yellow leak search additive. This pigment mixes with the engine oil and becomes visible when a UV lamp is shone on the leak point, causing it to glow brightly. This method is highly effective for Audi oil leak detection.

The intensity of the leak can vary; some leaks might be evident at idle speed, while very small leaks may require a test drive to become apparent. The additive is safe for use in both gasoline and diesel engines and does not necessitate an oil change after its application.

Important Warnings for Owners

Owners and technicians should be aware of specific advisories related to this Audi oil leak detection procedure:

• Do not use this additive for locating transmission leaks; it is specifically designed for engine oil.
• Engine cleaning before following the instructions is not necessary.
• There is no danger of damaging the engine if extra additive is put in, though recommended quantities should generally be followed.

Repair Procedure Summary

The diagnostic procedure for Audi oil leak detection involves two main steps for technicians:

1. Additive Application: One bottle of leak search additive (part number G 052 940 A1) is added to the engine via the oil filler neck. This quantity is sufficient for up to 5 quarts of engine oil. For engines requiring larger oil quantities, double the additive amount should be used.
2. Leak Identification: The engine is then run, and a UV lamp (such as VAS 231005 or equivalent) is used to scan the engine area. The fluorescent additive will glow under the UV light, clearly indicating the precise location of the oil leak.

Required Parts and Tools

To perform the Audi oil leak detection procedure outlined in TSB 2060750/3, specific items are required:

• Leak search additive: Part number G 052940A1
• UV lamp: Tool number VAS231005 (WVA-074) or equivalent
• Fasteners, Bolts, Nuts, and Screws: As needed, per the repair manual (refer to ETKA for details).

Warranty Information

It is important for owners to note that Technical Service Bulletin 2060750/3 is informational only. This means the procedures described within it are not applicable to any Audi Warranty coverage. Owners should consult with their dealership regarding any potential costs associated with diagnosing or repairing oil leaks.
