2022-2024 Audi e-tron GT Cooling Insufficient TSB P2B3000 P2B3200

Audi has released Technical Service Bulletin (TSB) 19 24 59 2073599/2 to address concerns regarding insufficient cabin heating or cooling, drive system malfunctions, and diagnostic trouble codes (DTCs) P2B3000 or P2B3200 in 2022-2024 Audi e-tron GT and RS e-tron GT models. This TSB supersedes an earlier bulletin, Group 19 number 24-57, dated April 8, 2024, and provides updated information for these issues.

This bulletin details how debris can obstruct the cooling fans, leading to various performance problems. The TSB outlines specific symptoms, diagnostic steps, and a repair procedure involving updated parts to prevent future occurrences of the Audi e-tron GT cooling insufficient P2B3000 problem.

Symptoms

Owners of affected vehicles may experience one or more of the following issues:

• Insufficient cabin heating or a complete lack of heating output.
• Insufficient cabin cooling or a complete lack of cooling output.
• Reduced vehicle drive power.
• The high voltage battery may not charge to its full capacity.

These concerns can vary depending on the driver's habits and environmental conditions.

Fault Codes / DTCs

When diagnosing these symptoms, technicians may find the following DTCs and symptom codes stored in the J1024 Thermal management control unit (address word 00C5):

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 is typically the mechanical blockage of one or both radiator fans. Debris, road dirt, or other foreign objects can enter the grille in the front wheel housing liner and accumulate, physically obstructing the cooling fan operation. This condition is more likely to occur if the vehicle is frequently driven on unpaved roads, exacerbating the Audi e-tron GT cooling insufficient P2B3000 issue.

Important Warnings

Audi specifies a crucial distinction for technicians and owners:

If a customer reports only hearing noise from the front of the vehicle, and none of the symptoms or DTCs described in TSB 19 24 59 2073599/2 are present, and the cooling fans are not mechanically blocked but merely making noise due to debris, technicians should first perform the solution outlined in TSB 2073030, titled "19 Grinding or knocking noises from electric cooling fans when active." This TSB (19 24 59 2073599/2) should only be followed if the specific symptoms and DTCs are present.

Repair Procedure Summary

Audi has implemented a production solution with improved cooling fans, shrouds, and wheel housing liners designed to reduce debris accumulation within the cooling fan mechanisms. For vehicles already in service, the repair involves replacing existing components with these updated versions.

Specifically, the new components feature larger openings on the underside to allow foreign objects to escape more easily and include a protective cap for the fan's electric motor to prevent dirt and debris from entering. If a cooling fan replacement is necessary, technicians must check the version of the wheel spoiler and wheel housing liner and replace all affected parts on the serviced side with the new, improved components.
