Keep your battery in good condition, have your front radar sensor cleaned during routine service, and ensure any windscreen or bodywork repairs near the front sensor are performed by a professional who can recalibrate the system.
Modern Renault vehicles depend heavily on a complex ecosystem of electronic control units (ECUs), interconnected sensors, and high-speed communication lines. When a component deviates from its optimal parameters, the vehicle's onboard diagnostics system triggers a manufacturer-specific code known as a code.
DF357 is a manufacturer-specific code for Renault vehicles, meaning it is not covered by the standard OBD2 code set and requires a diagnostic tool that can read Renault's proprietary codes.
