    Knocking sound in Toyota Prado

    Toyota Toyota Advice Toyota Prado Toyota Prado Advice Toyota Landcruiser Prado 2008
    There is an intrusive knocking sound from the motor in my 2008 Toyota Prado 3.0-litre turbo-diesel when trying to drive on a cold start. Even if I let it idle for five minutes to warm up it still persists until the motor is at full operating temperature. If I drive it before it is completely warm any load on the motor, like going up a hill or accelerating produces a very distressing knocking sound. Is this normal, how can it be fixed?

    We were told of a similar issue with the turbo-diesel engine in the HiLux, which was claimed to be cause by over-fuelling during the warm-up phase and there was a revised ECU developed to fix it. Go back to your dealer and check the availability of the fix for your car.
