    KNOCK SENSOR

    Audi a4 TDI (B6) 1.9 awx engine.
    Any ideas where the knock sensor is located,and if its a fault that would show up on vag-com (sensor advances and retards timing)

    Hi vw754
    As far as I know, knock sensors are only fitted to petrol cars, not diesels.

    Cheers Spike

    the knock sensor is only fitted to petrol engined cars as spike mentioned, and its to detect premature ignition, in one of its many forms. This is not possible with a diesel as the fuel ignites the moment it is injected so it cannot pre-detonate.

    Whats wrong with your engine that would make you want to locate the knock sensor, describe the problem and we'll try and help.

    The problem with common sense, is that its not that common.
