Are you looking at a used Clio or Note with the 1.5 dCi DF357? Use this checklist to avoid buying a money pit.
The Renault DF357 is a rare and elusive truck model that has captured the hearts of enthusiasts and collectors around the world. Its impressive performance capabilities, rugged design, and rich history make it a standout in its class.
The sensor itself might be faulty or dirty, failing to read the ring correctly. 3. Wiring and Connector Issues
In rarer cases, the internal electronics of the ABS unit itself can fail, leading to an incorrect voltage reading. How to Diagnose and Fix DF357
: This is the most common culprit. If the physical switch at the top of your brake pedal is sticky, worn, or misaligned, the digital signal fails. renault df357
The Renault Df357 is designed to be easy to maintain and service, with a range of features that help to minimize downtime and reduce operating costs. Some of its key maintenance and service features include:
If equipped, emergency active braking and lane-keeping functions will go offline.
Use a tool like Renault CLIP or an OBDII scanner to confirm which module is hosting the DF357 code.
: Low battery voltage during startup can sometimes trigger "ghost" multiplex codes like DF357. Diagnostic and Repair Steps Are you looking at a used Clio or Note with the 1
: Using an OBD2 scanner , clear the code and see if it returns immediately. If it only returns under certain conditions (like using cruise control), it points toward a signal "coherence" issue.
The DF357 uses a specific injector clamping system. Over time, the clamp bolts can relax or the copper sealing washers can fail. This leads to "chuffing"—a loud ticking noise from the top of the engine, followed by black soot building up around the injectors. If ignored, combustion gases will erode the cylinder head, requiring a full head replacement or a new engine.
The ABS or Electronic Stability Program (ESP) warning lights may appear on the dashboard.
Sometimes the issue lies within the Electronic Control Unit (ECU) communicating with the ABS or braking module JustAnswer. How to Diagnose and Fix DF357 Wiring and Connector Issues In rarer cases, the
Locate the component associated with the code. Carefully inspect its wiring loom for signs of stretching, heat damage from the exhaust manifold, or brittle insulation. Disconnect the sensor plug to verify that the internal metal pins are clean, tight, and free of green copper corrosion. 4. Multimeter Continuity Diagnostics Set a digital multimeter to the resistance ( Ωcap omega
: In models like the Renault Megane , DF357 is often associated with the CVT control system. It can indicate a communication error or a sensor fault within the gearbox module.
Systems like Cruise Control, Speed Limiter, or Hill Start Assist may stop working. 3. Troubleshooting Steps To resolve a DF357 fault, follow these diagnostic steps: BRAKING FAULT Renault Error [SOLVED] Depleted Car Battery
: Since Renault codes (DF) are manufacturer-specific, they are best read using a Renault CAN Clip or a compatible diagnostic tool like Carista to get the full technical sub-description (e.g., "1.DEF" or "CC.0").
In many Renault models, such as the Grand Scenic IV, DF357 often points to a fault in the ABS system. It is frequently linked to a failing wheel speed sensor (often the front left) or issues with the wiring harness connecting these sensors.
