Technical Background

This issue, where the Audi e-tron GT radiator fan stuck condition arises, is often caused by foreign objects or dirt entering the fan module. Frequent journeys on unpaved roads, gravel surfaces, or gritted roads significantly increase the likelihood of this complaint occurring due to increased exposure to debris.

Production Solution

Audi implemented a production solution to address this problem, with vehicles manufactured from March 2023 onwards incorporating design changes. These vehicles are equipped with updated components intended to prevent foreign objects and dirt from causing the radiator fans to stick.

Repair Procedure Summary

Technical Service Bulletin 2073599/3 outlines the procedure for addressing the Audi e-tron GT radiator fan stuck issue. If the complaint involves grinding or knocking noises from the electric cooling fans when active, technicians are advised to first consult TSB 2073030, titled "19 Grinding or knocking noises from electric cooling fans when active," and then reassess the complaint.

The repair involves replacing specific components with updated versions that have been modified to prevent dirt and stones from entering the fan motor. These new components feature larger openings on the underside to allow foreign objects to escape and a protective cap on the fan's electric motor to prevent debris ingress.

When replacing a fan as part of this TSB 2073599/3, technicians must check for any other old component versions in the vehicle and replace them with the corresponding new component versions. The procedure should focus on the side of the vehicle affected by the complaint.

For example, if the right-side fan (part number 9J1121205C) is the source of the complaint, technicians should check and replace all components on the right side of the vehicle with their new versions as listed in the table below.
