    Hello.
    I have Astra H 1.3 CDTI. Errors: P0110 and P0100. I've already replaced 3 MAF sensors, and it still doesn't work. It only starts above 40 °C (then I can connect the MAF sensor connector). If it's cold, it only starts with the MAF sensor disconnected. I took some measurements (disconnected MAF) and I have 5 V and 12 V.
    Can anyone offer some advice? The first image was accelerating in the car.

    AI: Have you checked the wiring and connectors for damage or corrosion, or tested the intake air temperature sensor and ECU for faults?
    All good.
    AI: Are there any other symptoms (like rough idle, loss of power, smoke, or high fuel consumption) or any other fault codes showing up besides P0110 and P0100?
    Don't start

    What does the engine controller see when it is cold and the engine is not running but the MAF is connected? What is the flow and temperature at the MAF sensor?
