To resolve DF357, follow this diagnostic workflow:
Step 1: Clear the Code Using a diagnostic tool (such as Renault CLIP, PyClip, or a generic OBDII scanner), clear the fault codes.
Step 2: Inspect Steering Wheel Controls
Step 3: Check Battery Voltage
Step 4: Wiring Checks
The 1.5 dCi engine family is a paradox. It is simultaneously one of the best small diesel engines ever made and one of the most finicky. The DF357 sits right in the middle of this paradox.
The DF357 represents the end of an era. It was the last pure "works" Renault turbo before the company pulled out of F1 for seven years. It was brutish, unreliable, and brilliant in fleeting moments.
In the modern world of hybrids and energy recovery, the DF357 is a dinosaur. But for collectors and historic racers, it is a holy grail. A running example changes hands for millions. Its sound—a high-pitched, staccato wail that transitions into a deep-chested roar as the boost comes on—is the audio signature of a time when F1 was lethally dangerous and spectacularly unpredictable.
The Verdict: The Renault DF357 wasn't the most reliable engine of its era, nor the most powerful. But in the hands of a genius like Senna, on a wet track, with the boost turned up and the electronics holding on by a thread, it was perfect.

The Renault DF357 diagnostic fault code is a specific manufacturer error often encountered by owners of Renault vehicles, particularly the Megane, Scenic, and Captur models. While generic OBD-II codes (P-codes) provide a basic starting point, Renault's "DF" (Diagnostic Fault) codes offer more granular data for specialized diagnostic tools like the Renault CLIP or Pyren.
Depending on your vehicle's configuration, DF357 typically refers to a communication or sensor error within the ABS/ESP system or the CVT transmission. Understanding DF357: Common Causes
Because Renault uses this code across different control modules, its exact meaning depends on which system is reporting it:
ABS and Stability Control (Most Common): In many chassis-related diagnostics, DF357 points to a problem with an ABS sensor or the ABS target ring (also known as a reluctor ring).
CVT Transmission: On Megane models equipped with a Continuously Variable Transmission (CVT), this code can indicate an internal transmission error or a communication fault between the transmission and engine control modules.
Secondary System Shutdown: Because the ABS system provides speed data to other modules, a DF357 fault often triggers a "cascade" of other errors, such as DF047 (Low Battery Voltage) or DF048 (Vehicle Speed Signal), which can disable safety features like Active Braking and Adaptive Cruise Control. Symptoms of a DF357 Fault
If your vehicle triggers this code, you may notice several immediate warning signs:
Dashboard Lights: The ABS, ESP (electronic stability), or "Spanner" service light will typically illuminate.
Safety System Deactivation: Messages like "Check Braking System" or "Check Anti-Pollution System" may appear, and cruise control may stop working.
Transmission Behavior: For CVT owners, the car might enter "Limp Mode," limiting engine power to prevent damage. Step-by-Step Diagnostic and Repair
If you encounter this code, it is recommended to follow a systematic troubleshooting process rather than replacing parts immediately.
Perform a Full System Scan: Use a tool like Renault CLIP or an OBDII scanner to confirm which module is hosting the DF357 code.
Inspect the ABS Rings: A common physical cause is a cracked or dirty ABS ring on the wheel hub. Debris or a small stone can damage the ring, leading to an "implausible signal".
Check the Sensor Wiring: Inspect the wiring harness leading to the wheel speed sensors. Corroded connectors or frayed wires are frequent culprits in older Renault models.
Verify Battery Health: Many Renault electronic modules are sensitive to voltage drops. Ensure your battery is providing a consistent 12.6V+ when off and 14V+ when running. The Repair Cost
Repairing a DF357 fault is often surprisingly affordable if caught early. Replacing an ABS reluctor ring can cost significantly less than replacing a full hub assembly if you use specialized parts from retailers like Euro Car Parts or Autodoc. However, if the fault lies within a CVT transmission, a professional rebuild or software reprogram may be required. renault df357

Understanding Renault Fault Code DF357: Causes and Fixes If you own a Renault Megane, Fluence, or similar model and your diagnostic tool just flagged DF357, you’ve likely noticed a sudden drop in performance or warning lights on your dash. This specific manufacturer code is often tied to critical safety and drivetrain systems, particularly the ABS/ESP or the CVT transmission.
In this guide, we’ll break down what DF357 means, why it happens, and how to get your Renault back on the road safely. What is Fault Code DF357?
In the world of Renault diagnostics, "DF" stands for Défaut de Fonctionnement (Malfunction Fault). While generic OBD-II codes like P0500 refer to vehicle speed sensors, DF357 is a Renault-specific code that usually points to a Wheel Speed Sensor Circuit or a communication issue within the ABS (Anti-lock Braking System) and ESP (Electronic Stability Program). Common Symptoms
Warning Lights: The ABS, ESP/Traction Control, and "Check Braking System" lights illuminate on the dashboard.
Limp Mode: The car may restrict engine power or prevent the cruise control from working to ensure safety.
Transmission Issues: On models with a CVT transmission, a DF357 error can trigger secondary transmission faults, as the gearbox relies on accurate wheel speed data to manage gear ratios. Primary Causes of DF357
The most frequent culprit for this code isn't actually a "broken" computer, but a physical failure at the wheels. 1. Damaged ABS Ring (Tone Ring) To resolve DF357, follow this diagnostic workflow: Step
This is the most common cause. The ABS ring is a toothed metal ring mounted on the wheel hub or axle. Over time, road debris (like a stray stone) or rust can chip or crack the ring. If the teeth are damaged, the sensor cannot read the wheel's rotation correctly. 2. Faulty Wheel Speed Sensor
The sensor itself—a small electromagnetic probe—can fail due to internal electrical shorts or external grime buildup. If it stops sending a signal to the ECU, DF357 is often the result. 3. Wiring Harness Damage
Renaults are known for sensitive electrical systems. Frayed wires or corroded connectors near the wheel arch can break the circuit between the sensor and the main ABS module. How to Diagnose and Fix DF357 Step 1: Identify the Affected Wheel
Use a specialized Renault diagnostic tool (like Carly for Renault or Renault CAN Clip) to see which specific wheel is reporting the error (e.g., "Left Rear Wheel Speed Sensor Circuit"). Step 2: Inspect the ABS Ring
Physically inspect the metal ring behind the wheel. Look for: Cracks in the ring. Missing teeth or heavy rust. Signs of impact from stones. Step 3: Check the Sensor and Wiring
Ensure the sensor is seated properly and that the wiring isn't rubbing against the suspension or tires. You can test the sensor’s resistance with a multimeter; if it reads "Open Circuit," the sensor needs replacement. Step 4: The Repair
If the ring is broken: You may need to replace the entire wheel hub or the axle assembly, though some models allow for the replacement of just the ring itself. A 36mm socket and Torx 60 bit are common tools required for this job.
If the sensor is faulty: These are relatively inexpensive and easy to swap out with basic hand tools. Expert Tip: Don't Ignore Secondary Codes DF357 rarely travels alone. You might also see:
DF047 / DF048: These often follow DF357 and indicate that the ABS and ESP systems have been disabled as a precaution.
DF038: Can indicate a broader internal electronic failure if the voltage to the sensors is unstable.
By fixing the mechanical issue at the wheel (usually the ABS ring), these secondary codes typically vanish once cleared with a scan tool.
Is your Renault currently in "Limp Mode," or are you just seeing the warning light for now?
