Renault Fault Code Df083 Jun 2026

Because Renault uses proprietary "DF" codes that are not always 1-to-1 with standard OBD-II (P-codes), DF083 can refer to several different circuits:

Each injector contains a solenoid coil with specific resistance (typically 0.5–2.5 ohms for diesel, 10–15 ohms for petrol). If the coil burns open (infinite ohms) or shorts internally (0 ohms), DF083 sets.

The driver will rarely see DF083 as a standalone code without experiencing notable drivability issues. Typical symptoms include:

Technically, DF083 corresponds to a fault in the , specifically indicating a coherence fault between the measured and expected position of the valve. In simpler terms, the engine control unit (ECU) commands the EGR valve to open to a certain percentage—say, 40%—to recirculate exhaust gases back into the intake manifold to lower combustion temperatures and reduce NOx emissions. The position sensor reports back what the valve is actually doing. If the ECU sends a signal for 40% but the sensor reports 70% or 0%, or if the signal is erratic, it logs DF083.
