2021-2022 Audi Rear Spoiler Malfunction TSB 2065220/2

Owners of certain 2021-2022 Audi A7, S7, RS7, e-tron GT, and RS e-tron GT vehicles may experience an Audi rear spoiler malfunction, indicated by a warning message in the instrument cluster and potential loss of spoiler operation. Audi has issued Technical Service Bulletin (TSB) 66 22 85 2065220/2 to address this issue.

This TSB, released on March 10, 2022, supersedes an earlier bulletin, Group 66 #21-79, dated December 7, 2021. It provides a comprehensive solution for the inoperative rear spoiler and associated diagnostic trouble codes (DTCs).

Diagnosis / Trigger Conditions

The root cause of this Audi rear spoiler malfunction is identified as insufficient pressure from the carbon brushes to the motor commutator within the spoiler drive motor. This can lead to a loss of contact, resulting in intermittent or permanent failure of the spoiler's operation. Audi has implemented a redesigned rear spoiler drive motor in production, featuring increased brush-to-commutator pressure to prevent this issue.

The repair outlined in TSB 66 22 85 2065220/2 involves a straightforward two-step process:

1. Replace the Rear Spoiler Drive Unit: The primary step is to replace the existing rear spoiler drive unit with a new, redesigned component. This addresses the underlying mechanical fault.
2. Complete ODIS Test Plan and Clear DTCs: After replacement, technicians must run the ODIS diagnostic test plan and clear any stored diagnostic trouble codes from the vehicle's systems.
