Locate the UCH fuse box (usually in the glovebox or engine bay). Check fuses related to the lighting system (e.g., F15, F16 – consult your owner’s manual). A blown fuse can create an open circuit that triggers DTC1525F3.
: Your dashboard likely displays a "Check Cruise Control" or "Check Speed Limiter" message.
In Renault’s diagnostic architecture, DTC 1525F3 generally indicates a “Turbocharger Pressure Control Function: Coherence” fault. The "F3" suffix often points to an electrical or range/performance issue within the actuator circuit. On the Megane 3 (particularly diesel engines like the 1.5 dCi K9K or 1.9 dCi, or even the 1.2 TCE petrol), this means the ECU detected a deviation between the target boost pressure and the actual reading from the boost pressure sensor, often coupled with a circuit abnormality in the turbo solenoid (e.g., open circuit, short to ground, or stuck position).
Because this code is generic, you must look for accompanying "primary" codes. Frequent culprits in the MĂ©gane 3 (especially the 1.5 dCi) include:
