  • Renault Trafic M9r error P0100 and P0409

    Good evening everyone! My name is Cristiano Pio.
    I own a 2009 Renault Trafic 2.0 dCi 66 kW with the M9R engine. No DPF.

    The vehicle starts and runs, but it has lost some power. The EGR valve is clean.

    My vehicle has fault codes P0100 and P0409. I have already tested the EGR valve and installed a new MAP sensor, but the error persists. I have checked the wiring and everything seems correct.
    Please help me solve this problem. Your experience or any advice you could provide would be greatly appreciated. Thank you.
