2023-2026 Audi Increased Engine Oil Consumption TSB

Symptoms

Owners of 2023-2026 Audi vehicles may notice their engine oil consumption is too high. This is typically reported by the customer, indicating a need to add oil more frequently than expected. Workshop findings often confirm there is no visible oil loss or residue, suggesting no external leaks or obvious technical causes for the increased consumption.

Diagnosis / Trigger Conditions

When a customer reports high Audi engine oil consumption, technicians will investigate the complaint. The primary diagnostic step involves objectively determining the actual engine oil consumption. This is done using a specific measurement process to rule out other issues and quantify the consumption rate. The TSB notes that there is typically no visible evidence of oil loss or any other technical cause found during initial inspection.

Repair Procedure Summary

To accurately measure the Audi engine oil consumption, an objective test specified by the manufacturer must be performed. This involves either an electronic measurement or a weighing method. For many models, an electronic measurement process utilizing the ODIS tester has been developed. This process is accessed on the ODIS tester under "Guided Functions" via the specific identifier "01/0001 – Oil Consumption measurement (electronic measurement, idle)".

If the electronic measurement process is not available for a particular model, the test program will automatically select the weighing method. When the weighing method is used, new engine oil must be added for the test. Repairs, such as part replacement, are only to be performed if the measured oil consumption exceeds the limit specified in the vehicle's Owner's Manual.

Important Warnings

Audi has issued several critical warnings regarding the oil consumption measurement process and associated costs:

• "Before starting any work, you must add a note to order informing the customer that the costs will be incurred for the oil consumption incurred for the oil consumption measurement when checking the complaint."
• "If the complaint about increased engine oil consumption is unjustified (consumption below the limit specified by the manufacturer), the customer must bear the costs for determining the engine oil consumption."
• "If the complaint proves to be unjustified, the customer must bear these costs."
• "The oil consumption measurement can only be invoiced under warranty if it is determined that the oil consumption is above the permissible limit specified in the Owner's Manual for the vehicle."
• "If part replacement is invoiced under warranty, the diagnostic log with the data from the oil consumption measurement must be sent online, otherwise we reserve the right to charge back the costs."
• Owners should "always refer to the information in your Owner's Manual" for details on permissible oil consumption levels.

Owner Action

If you are experiencing increased Audi engine oil consumption in your 2023-2026 Audi, it is recommended to schedule an appointment with an authorized Audi dealer. Be prepared to discuss the potential costs associated with the oil consumption measurement, especially if the consumption is found to be within the manufacturer's specified limits. Ensure you consult your vehicle's Owner's Manual to understand the normal oil consumption parameters for your specific model.
