: Can indicate an issue with "Thermoplunger relay number 2" or a fault in the cooling fan circuits (Fan 1 or Fan 2).
It is important to note that DF104 is a stored or present fault code, and depending on the system and specific interpretation, it can be categorized as a Medium or High-priority issue that requires attention. Driving with an active DF104 code—especially one related to the brakes or transmission—is not recommended.
When the ABS/ESP computer loses a clean multiplex signal or reads data outside preset tolerances from this module, it triggers the fault. renault df104 new
The is a manufacturer-specific diagnostic code indicating a critical communication or hardware breakdown within your vehicle’s electrical sub-systems. If you are encountering a new instance of this error, it typically points to one of two main areas depending on your vehicle model: an internal electronic failure in the ABS/ESP combined sensor (yaw rate/lateral acceleration sensor), or a data mismatch in the cabin blower motor/climate control circuit .

You must use a Renault-specific CAN Clip tool to identify if the error is "Current" (active) or "Stored" (history). A "Current" error suggests a live issue with wiring or modules, while "Stored" might indicate a temporary voltage drop. Step 2: Inspect Water Leakage (Crucial New Step)
Builders are pulling the heavy modern F4R engines out of Renault Clios and dropping "new" DF104 units into lightweight replicas of the Alpine A110 and Lotus Seven. With electronic ignition (retrofitted) and fuel injection, these "restomod" DF104s produce a reliable 190bhp.
To clear a new DF104 code permanently without blindly swapping expensive modules, follow this logical diagnostic process:
Check for signs of moisture or corrosion around the module (usually located behind the center console).
