Renault Df357 -

Common symptoms include:

When the DF357 code triggers, you will rarely experience it purely as a silent code. The vehicle's Multiplex (CAN bus) system will instantly enter a defensive profile, triggering several noticeable symptoms on your instrument cluster:

: The main ABS light illuminates alongside the orange "spanner" service light or traction control icon.

| Fault Code | Description | Primary System | Typical Solution | | :--- | :--- | :--- | :--- | | | Invalid data received from adaptive cruise control | ABS/ESP Module | Check battery, grounds, ACC radar, wiring to ABS. | | DF001 | Computer power supply, open circuit or short to +12v | ABS/ESP Module | Check and secure main battery connections, alternator, and ABS module fuse/relay. | | DF118 | Multiple rear wheel speed signal, right and left inconsistency | ABS/ESP Module | Inspect, clean, or replace a faulty rear wheel speed sensor or reluctor ring. | | U0235 | Lost communication with cruise control front distance range sensor | Communication (CAN Bus) | Check wiring and connections to the front radar sensor. | | U1000 | Class 2 Communication Malfunction (SCP - J1850) | Communication (CAN Bus) | Indicates a general communication failure on a specific network bus. Requires global CAN bus diagnostics. | renault df357

By understanding that DF357 is a "communication breakdown" and methodically checking the electrical infrastructure, you can effectively resolve this fault and restore full functionality to your Renault's driver-assist and safety systems.

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.

The engine became infamous for its "push-to-pass" concept before the term existed. In qualifying trim, the DF357 would run a lean fuel mixture with water-injection cooling. Mechanics would freeze the intercoolers with dry ice before a hot lap. The result was a shrieking, anti-lag-banging monster that sounded less like an engine and more like a jet turbine tearing itself apart. Common symptoms include: When the DF357 code triggers,

Damaged ABS rings (often caused by corrosion or rocks) or faulty ABS sensors can create erratic data, which the computer interprets as a supply voltage issue.

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.

Because this is a powertrain code, the DF357 didn't just appear in Renault-badged cars. Thanks to the alliance between Renault and Nissan, this engine proliferated across multiple brands. You will find the DF357 in the following vehicles (manufactured roughly between 2005 and 2010):

Renault employs a proprietary diagnostic protocol where "DF" stands for Défaut Fonctionnel (Functional Fault). Unlike generic OBD-II codes (such as P0300 or P0100), Renault-specific DF codes provide a deeper level of granular data when scanned using dedicated diagnostic multiplexers like the tool or advanced multi-brand scanners.

DF357 is rarely a catastrophic engine failure. It is primarily a communication fault regarding the cruise control logic. Begin diagnostics by clearing the code and checking battery health, followed by testing the functionality of the steering wheel buttons via live data.
