If your car is showing a "hot" or overheating warning alongside a diagnostic light, it is frequently related to:
Coolant Temperature Sensor (DF001): A faulty sensor can trigger overheating warnings or "Check Injection" messages.
Upstream Turbine Pressure Issues: Common on 1.5 dCi engines, a blocked pipe or faulty Upstream Pressure Sensor can cause the car to enter limp mode, though it usually triggers codes like DF569 or DTC 047195.
Turbine Temperature Sensors: Some Renault models use specific exhaust gas temperature sensors that, if failing, might report a "hot" condition to the ECU. Recommended Next Steps
Verify the Code: Use a Renault-specific scan tool (like CLIP or Pyren) to confirm if the code is actually DF057 (Oxygen Sensor) or DF357 (which may be a specific manufacturer sub-code not found in general lists). renault df357 hot
Check Live Data: Look at "Coolant Temperature" and "Exhaust Gas Temperature" in your scan tool's live data to see if any reading is abnormally high (e.g., sticking at
Inspect Connections: For any "hot" or circuit-related fault, check for melted wiring near the exhaust manifold or turbocharger, as this can cause short circuits.
Could you clarify which model and engine (e.g., Megane 1.5 dCi) you are working on to help pin down the exact sensor? AI responses may include mistakes. Learn more
First, forget the Renault cars (Clio, Megane). The DF357 is a legendary workhorse in the industrial diesel engine family. It is a 4-cylinder, direct-injection, liquid-cooled diesel engine, typically displacing around 3.5 to 3.8 liters. If your car is showing a "hot" or
You will find this engine in:
The DF357 earned its reputation for being over-engineered, torquey, and extremely reliable when properly maintained.
If you are searching for "DF357 Hot," it is likely because you notice the car drives fine when cold, but acts up after 20–30 minutes of driving.

If you’ve been scanning automotive forums, tuning databases, or French car specialty sites, you’ve likely encountered the cryptic phrase: Renault DF357 Hot. For the uninitiated, this combination of letters and numbers might look like a factory error code or a forgotten industrial part. For Renault enthusiasts, however, the DF357 represents a critical engine component, and the word "Hot" signals a complete shift in performance philosophy.
In this comprehensive guide, we will dissect exactly what the DF357 is, why the “Hot” variant has become a cult classic in the hot hatch community, and how you can maximize its potential without sacrificing reliability.
The short answer: No.
The longer answer: The DF357 was killed by the shift to turbocharging. When Renault saw what the 1.4-litre turbo could do with 160 bhp and far lower manufacturing costs, the expensive, high-strung 2.0-litre DF357 was shelved. Most of the castings were reportedly crushed. What is the Renault DF357
However, the legend lives on. A handful of replica DF357 "Hot" specs have been built by privateers using rare Gordini cylinder heads and custom cranks. If you ever see a Renault R18 with side-exit exhausts and a suspiciously lumpy idle at a French classic car meet, walk over and listen closely. If it sounds like a BMW M3 on espresso, you might have just found the ghost of the DF357.
