2022-2026 Audi Engine Oil Leak Detection TSB 2060750/5

Symptoms of an Engine Oil Leak

Owners of affected Audi vehicles may notice an Audi engine oil leak in the area of the front end of the vehicle or within the engine compartment. Technicians performing inspections have also confirmed the presence of oil leaks in the engine area during workshop findings.

Diagnosis and Trigger Conditions

This Technical Service Bulletin (TSB 2060750/5) provides a method for precisely locating engine oil leaks. The process involves using a fluorescent yellow leak search additive, G 052 940 A1. This pigment mixes with the engine oil and glows brightly when illuminated by a UV lamp, making even very small leaks visible. This diagnostic method is suitable for both gasoline and diesel engines, and an oil change is not required after the additive is introduced. Engine cleaning is not necessary before performing this procedure.

Repair Procedure Summary

To diagnose an Audi engine oil leak, technicians will follow a straightforward process:

1. Additive Application: 10 mL of the leak search additive G 052 940 A1 is added to the engine via the oil filler neck. This amount is sufficient for up to 5 quarts of engine oil; larger oil quantities require double the amount. There is no risk of engine damage if extra additive is used.
2. Leak Detection: The engine is then run, and a UV lamp (such as VAS 231005 or equivalent) is used to locate the exact point of the oil leak. The fluorescent additive will highlight the leak under UV light.

It is crucial to note that the UV leak detection additive G 052 940 A1 is specifically for engine oil and is not approved for use in gearboxes to locate transmission leaks.

Required Tools or Parts

Technicians will need specific items to perform the leak detection and subsequent repair:

• Leak Search Additive: G 052940A1 (10 mL)
• UV Lamp: VAS231005 (WVA-074) or an equivalent tool
• Fasteners, Bolts, Nuts, and Screws: As needed, per the Repair Manual (See ETKA)

Owner Action

If you suspect your Audi vehicle has an Audi engine oil leak, it is recommended to schedule an appointment with an authorized Audi service center. They will use the procedure outlined in TSB 2060750/5 to accurately diagnose the source of the leak. Warranty coverage for this service (Service Number 1701, Damage Code 0055) will depend on your vehicle's warranty status; if the vehicle is outside of warranty, this bulletin serves as informational guidance.
