Renault Df357 __top__ Jun 2026
Because Renault uses this code across different control modules, its exact meaning depends on which system is reporting it:
The DF357 code explicitly monitors the of a dedicated actuator or sensor subsystem. Depending on the exact engine variant—such as the highly prevalent 1.5 dCi (K9K), 1.6 dCi (R9M), or TCe turbocharged petrol variants—the code frequently points to a fault in the auxiliary emissions circuit, turbocharging control system, or electronic throttle track inputs. Primary Causes of the DF357 Code
: Plug in a dedicated Renault-compatible tool (such as PyRen, CAN Clip, or an advanced OBD2 multi-system scanner). Navigate to the ABS parameters menu and view live wheel speed graphs while driving the car forward at a slow, straight crawl. Look for the specific wheel wheel that reads 0 km/h or intermittently drops its speed signal.

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 diagnostic trouble code is a manufacturer-specific fault code primarily associated with the electronic control systems of modern Renault passenger and commercial vehicles. When triggered, it indicates an electrical circuit anomaly or data signal mismatch detected by the Engine Control Unit (ECU) or the Injection Control Module. Understanding the nuances of the DF357 code helps automotive technicians and owners isolate the underlying fault, restore vehicle driveability, and clear the dashboard warning indicators. Technical Context of Renault DF-Series Codes
Understanding the root causes, driving symptoms, and repair procedures for DF357 can prevent unexpected breakdowns and expensive dealership diagnostic fees. What Does the Renault DF357 Code Mean? Because Renault uses this code across different control
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.
is a manufacturer-specific diagnostic trouble code (DTC) that primary points to a malfunction within the gaspedal position sensor (accelerator pedal sensor) circuit , though on certain vehicles equipped with a continuously variable transmission (CVT), it can also trigger a transmission control unit alert. When this code registers in the Engine Control Unit (ECU), the vehicle usually limits engine power to protect the mechanical components, commonly known as "limp mode."
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. Navigate to the ABS parameters menu and view
In Renault's internal diagnostic system, The manufacturer's official description also includes "Internal component failure". This is a proprietary Renault code, meaning it goes beyond generic OBD2 standards. The OBD2 standard allocates specific codes for engine (P), chassis (C), body (B), and network (U) issues, but DF357 sits in Renault's own diagnosis table.
When these steps fail, the issue likely resides in the software configuration (requiring a dealer update) or a hardware failure in a specific sensor or module. In these cases, the vehicle should be taken to a specialist with the proper diagnostic equipment, such as Renault's CLIP tool, which can perform advanced functions like radar calibration.
