Owners of 2022-2023 Audi S3 vehicles equipped with the 4-cylinder 2.0 TFSI engine may observe oil residue in the engine compartment. This condition is specifically addressed by Audi Technical Service Bulletin (TSB) 01 23 67 2071200/1, issued on August 10, 2023. The TSB provides guidance for diagnosing and repairing this issue, ensuring proper vehicle function and cleanliness.

Symptoms

The primary symptom reported by customers and identified by workshops is the presence of "oil residue on charge air pressure pipe in engine compartment." More specifically, technicians have found "oil residue on the sealing point between charge air pressure pipe and cut-off valve."

Technical Background

Audi has identified that the root cause of the oil residue is a leak occurring at the connection point between the charge air pressure pipe and the cut-off valve. This leak allows oil to escape, leading to the visible residue in the engine compartment. The manufacturer implemented a production solution to address this issue starting in calendar week 24 of 2022.

Repair Procedure Summary

To resolve the Audi S3 charge air pipe oil residue condition, the TSB outlines a straightforward repair process. The main step involves replacing the charge air pressure pipe. This procedure should be performed according to the instructions found in ETKA, Audi's electronic parts catalog. It is crucial to note that the TSB explicitly states, "Replacing the cut-off valve, item 22, is not required." The labor operation code for replacing the charge air pressure pipe is 2141 5534.

Required Parts and Tools

For this repair, technicians will need to consult ETKA for the specific part number of the charge air pressure pipe, as one unit is required. Additionally, any necessary fasteners, bolts, nuts, and screws should be sourced as indicated in the repair manual via ETKA/ELSA.
