    I have a 400 1.9TDI.
    The alternator recently failed and since I have replaced it and charged
    the battery the alarm light continuous blinks when driving.
    How can I switch this off?
    I understand it indicates that the alarm has been activated.

  2. I have a 400 1.9TDI.
    How does that alarm light look and is it placed in the instrument housing?

    Try disconnecting and reconnecting the battery again. I found in my 940
    sometimes the alarm doesn't boot correctly if you connect the battery

    It might think its in learn mode or something.

    The light is located in the centre console.
    The manual tells me that if it is flashing all the time then the alarm
    has been triggered. This happened when I had the break down and had to
    open the car with the key.

    I have disconnected the battery a few times since but to no avail.

    I thought you said it happened after the alternator was replaced? Or do
    you mean you triggered the alarm once by opening the door when the alarm
    was armed. Did the horn start sounding?

    So can you not disarm the alarm with the keyfob?

    Does it not trigger the horn and disable the engine?

    ie does the alarm arm/disarm normally?

    My 940 alarm LED blinks when it is disarmed but the sensors are
    activated, such as open doors. Maybe the bonnet switch wire was cut or
    pulled off when the alternator was replaced.

  6. The light is located in the centre console.
    does it blink 1, 2 or 4 times a second?

    I think it blinks about 4 times a second.

  8. 4 times a second means some sort of system error.
