The code is a Renault-specific diagnostic trouble code (DTC) often linked to a disruption in the communication between vehicle sensors and the main computer. It frequently appears when the Airbag Computer (UPC) or the transmission control unit detects an inconsistency in speed or electrical stability, notes Scribd.
By fixing the mechanical issue at the wheel (usually the ABS ring), these secondary codes typically vanish once cleared with a scan tool.
: Carefully prize off the old, split magnetic ring using a flat screwdriver or punch. Clean the mating shoulder on the hub thoroughly with a wire brush and brake cleaner to remove rust scaling. renault df357

The adaptive cruise control system relies on a radar sensor, usually located behind the front grille or bumper, to monitor the distance to the vehicle ahead. If this sensor malfunctions, it cannot provide valid data, leading to a DF357 code on the ABS side that is expecting that data. The code is a Renault-specific diagnostic trouble code
Wheel speed sensor leads are constantly exposed to water, road salt, and harsh suspension movement. Over time, the wiring insulation can split, allowing water intrusion that triggers intermittent "Open Circuit" or "Short Circuit" conditions, turning a persistent code into a fluctuating headache. 3. Heavy Accumulation of Debris and Ferrous Metallic Dust
Fault code is a diagnostic trouble code (DTC) specific to Renault and Dacia vehicles equipped with electronic throttle control (fly-by-wire). This code indicates a communication error or data incoherence between the engine ECU (Electronic Control Unit) and the cruise control/speed limiter system. : Carefully prize off the old, split magnetic
Among these proprietary codes, stands out as a critical diagnostic trouble code (DTC) that can significantly degrade vehicle drivability. It is often tied closely to data inconsistency within multiplexed networks, the Anti-lock Braking System (ABS), and modern Advanced Driver Assistance Systems (ADAS). Direct Overview: What Does Renault DF357 Mean?
If you are dealing with a Renault Megane, the Drive2 community recommends checking the magnetic ring first, as it is a frequent point of failure leading to the DF357 error.
The Renault DF357 diagnostic trouble code, while initially alarming, is a solvable problem. It is a communication error between your car's ABS/ESP stability control system and its adaptive cruise control system.
When the vehicle registers the DF357 fault, the ECU typically deploys safety protocols to protect the powertrain. Drivers may observe several distinct symptoms:
