Renault DF104 is a specific diagnostic trouble code (DTC) often encountered by owners of Renault vehicles, particularly the Clio, Megane, and Scenic models. This fault code generally points to an issue within the passenger-side front airbag circuit, specifically referring to an open circuit or a communication failure.
While the code points to the airbag, the physical airbag unit is rarely the culprit. The most frequent causes include: Wiring issues under the passenger seat. Loose or corroded electrical connectors.
Once the physical repair is complete, the DF104 code may not disappear automatically. You will likely need a diagnostic tool to clear the stored fault from the ECU memory. If the repair was successful, the dashboard warning lights should stay off upon the next ignition cycle.
