Renault Df Fault Code List __full__ Jun 2026
Below is a list of frequently encountered Renault DF fault codes and their corresponding universal OBD-II (P) codes and descriptions. Description Coolant temperature sensor circuit DF002 Air temperature sensor circuit DF004 Boost pressure sensor circuit DF007 Rail pressure sensor circuit DF011 Sensor supply voltage No. 1 DF015 Main relay control circuit DF025 Preheating unit diagnostic connection DF026 Injector control circuit - Cylinder 1 DF027 Injector control circuit - Cylinder 2 DF028 Injector control circuit - Cylinder 3 DF029 Injector control circuit - Cylinder 4 DF038 Engine Control Module (ECM) / Calculator fault DF053 Rail pressure regulation function DF056 Air flow sensor circuit DF120 Engine speed sensor signal DF195 Camshaft / Engine speed sensor consistency DF209 EGR valve position sensor circuit DF297 Particle Filter (DPF) blockage DF569 Boost circuit (Turbocharger) performance DF645 Air intake flap position regulation Critical Faults & Troubleshooting Tips
Ignoring DF codes can lead to limp mode, failed MOT (emissions), or even immobilization.
To accurately read and clear these codes, you should use specialized software that can translate DF codes: renault df fault code list
While generic scanners often display standard "P" codes (e.g., P0115), professional-grade tools like Renault Clip or specialized OBD-II scanners will show the DF equivalent. A single DF code can sometimes have different meanings depending on the specific vehicle system it is reporting from, such as the Engine Control Unit (ECU) or the Anti-lock Braking System (ABS).
Understanding Renault DF (Défaut Fabricant) fault codes is essential for diagnosing issues in Renault and Dacia vehicles. Unlike universal OBD-II "P" codes used by all manufacturers, DF codes are manufacturer-specific and provide deeper diagnostic insights into Renault’s proprietary systems. What are Renault DF Codes? Below is a list of frequently encountered Renault
Renault frequently releases firmware updates that remove spurious DF codes. A 2015 Megane may show DF052 (EGR) falsely if software is outdated.
Understanding the is essential for any mechanic or DIY enthusiast. This article provides a complete, categorized breakdown of the most common DF codes, what they mean, and how to fix them. To accurately read and clear these codes, you
These codes frequently appear across popular models like the Clio, Megane, and Master. Corresponding P-Code Description Typical Symptoms Coolant Temperature Sensor Circuit Radiator fan runs constantly; hard starting Air Flow Sensor Circuit (MAF) Poor acceleration; "Limp Mode" Glow Plug Control Unit Liaison Hard starting in cold weather (Diesel only) Injector Cylinder 1 Control Circuit Misfiring; rough idle; engine shaking Rail Pressure Regulation Function Engine stalling; loss of power under load Particle Filter (DPF) Blockage "Check Injection" light; reduced fuel economy Boost Circuit (Turbocharger) Hissing sound; sudden loss of power Deep-Dive into Critical Systems 1. The Fuel & Injection System
If you have a persistent DF code not listed here, consult a Renault specialist with genuine CLIP software. Many "ghost" DF codes are solved by a simple BSI reset or ECU reprogramming.
When a DF code is logged, the ECU stores a "freeze frame" (engine RPM, coolant temp, speed, voltage). Always check this. A code like (turbo regulation) at 2000 RPM vs 4000 RPM changes the diagnosis.
