I have a 110 hp Peugeot 307 1.6 HDi. When I slow down, it gives a "Depollution System Fault" error, turns on the fault light, and power drops. Sometimes the car drives normally while this fault light is on, and sometimes I'm grateful if I can reach 100 km/h. Everyone in the industry said it was the "N75" solenoid, and we replaced it. But the problem didn't go away. When I take the car on a long trip and drive at 3,000 rpm for an hour, the light goes off, but if I press it three times, the fourth time, the light comes back on. Two of us went to the hood, hit the gas, and the car went into the circuit breaker. After 2-3 seconds, the shaft on the turbo moved slowly. That's why I'm starting to think the turbo vanes are stuck due to soot. (When we connect it to the OBD device, we get a turbo overboost error.) Premium307HDI2024-09-08 01:34:12
