• there are intermittent lighting failures or errors related to the inner left rear lamp,
• it is necessary to restore the factory wiring after incorrect installation modifications.

Choosing an original harness from the Cables, Harnesses, and Connectors group reduces the risk of compatibility issues and also simplifies future diagnostics, as the system remains consistent with Audi's service documentation.
