2022-2024 Audi e-tron GT / RS e-tron GT Cooling Fan DTCs P2B3000 P2B3200

Symptoms

Owners of 2022-2024 Audi e-tron GT and RS e-tron GT vehicles may notice several issues related to the cooling system and drive power. These symptoms can include insufficient cabin heating or a complete lack of heating output. Similarly, cabin cooling might be insufficient or entirely absent.

Beyond climate control problems, drivers might experience insufficient vehicle drive power, indicating a performance reduction. Another significant concern is when the high voltage battery does not charge to its full capacity. The manifestation of these issues, such as the Audi e-tron GT cooling fan P2B3000 problem, can vary based on the owner's driving style and ambient conditions.

Fault Codes / DTCs

When these symptoms occur, technicians may find specific Diagnostic Trouble Codes (DTCs) stored in the J1024 Thermal management control unit, identified by address word 00C5. These codes point to issues with the cooling fans:

DTC Code	Symptom Code	Description
P2B3000	59328	Fan 1 stuck on
P2B3200	59342	Fan 2 stuck on

Diagnosis / Trigger Conditions

The root cause of these issues, including the Audi e-tron GT cooling fan P2B3000 and P2B3200 codes, is often the mechanical blockage of one or both radiator fans. Debris such as road dirt, leaves, or other foreign objects can enter the grille through the front wheel housing liner. This accumulation can prevent the cooling fans from operating correctly. This condition is particularly prevalent in vehicles frequently operated on unpaved roads, where the likelihood of debris ingress is higher.

Repair Procedure Summary

Audi has implemented production solutions to mitigate debris accumulation in the cooling fan mechanisms. These improvements include redesigned cooling fans, shrouds, and wheel housing liners. The updated components feature larger openings on the underside, allowing foreign objects to escape, and a protective cap over the fan's electric motor to prevent dirt ingress.

For vehicles exhibiting the symptoms and DTCs P2B3000 or P2B3200, the repair involves replacing the affected components with the updated versions. This includes checking and replacing the wheel spoiler and wheel housing liner on the serviced side with the new version components. The Technical Service Bulletin 2073599/2 outlines this repair process.

Important Warnings

Owners should be aware of a specific diagnostic distinction. If you only hear noise from the front of the vehicle, and none of the symptoms or DTCs (like P2B3000 or P2B3200) described in this TSB are present, and the cooling fans are not mechanically blocked but merely making noise due to debris, do not proceed with the repair steps outlined in TSB 2073599/2. Instead, perform the solution specified in TSB 2073030, titled "19 Grinding or knocking noises from electric cooling fans when active," and then reassess the situation. This ensures the correct repair is applied based on the specific diagnostic findings.
