Dtc1525f3 | Renault

After some research and advice from a Renault specialist, this code points to a fuel pressure regulator issue – specifically “Fuel Pressure Regulator Coherence” or a circuit malfunction on the high-pressure fuel rail. In plain English: the ECU is seeing a fuel pressure value that doesn’t match the expected range.

On Renaults with the 2.0 dCI (M9R engine), also check the fuel pressure sensor wiring near the EGR valve – heat damage is common. renault dtc1525f3
