If you pull a DF357 code using a Renault-compatible diagnostic tool (like CAN Clip or an advanced OBD2 scanner), follow these troubleshooting steps: 1. Check Fluid Level and Quality
Renault electronics are sensitive to voltage drops; a dying battery can trigger "ghost" codes across multiple systems. Recommended Steps
In some older Renault models (like the Laguna II or Megane II), the ECU software might need an update to calibrate how the temperature signal is interpreted, though hardware failure is more likely.

If the problem persists, the next step is a physical inspection.
Some users report DF357 appearing alongside other ABS-related codes (like DF001), suggesting a broader issue with the ABS wiring harness or battery voltage. Potential Causes
