If the vehicle triggers the DF357 hot code immediately upon a cold startup, the culprit is a failed transmission fluid temperature sensor. Use live data on your diagnostic scanner to check if the temperature reading looks logical. A reading of 150°C on a freezing morning points directly to a shorted sensor or damaged wiring harness. 4.

Automotive electronics are highly susceptible to thermal breakdown. A vehicle may start and idle perfectly fine while cold, only to throw the DF357 code after 20–30 minutes of highway driving or urban gridlock. renault df357 hot

The is a manufacturer-specific diagnostic trouble code (DTC) that commonly points to a multiplexed brake switch information error or a wheel speed sensor/ABS ring malfunction across several Renault models like the Fluence, Megane, and Scenic. When this code triggers a "hot" status, it indicates an active, present fault that requires immediate diagnostic intervention.

Tackling this code requires a systematic approach. Here is a proven path based on owner experiences.
