Clicking & headlights flash -no crank

    BMW 3 SERIES E46- X PLATE 325i AUTO 2.5

    BACKGROUND.....
    1. Ran 100% perfect.
    2. Instant fire up every time.
    3. No smoke no warning lights on dash.

    SYMPTOMS.....
    1. Out of the blue on start up clicking noise. Interior & headlights flash at the same time. No fire up.
    2. With ignition on headlights appear normal/bright, not dimmed.
    3. Battery reads 11.4v

    My first instinct was a dodgy starter but the lights flashing is a first for me...

    Any help much appreciated, thank you

    I think, you need to get the car on a diagnostic computer preferably with live data so all the inputs and outputs can be seen while the car is starting.
    11.4V is very low, it may be worth charging the battery, and then try on a fully charged battery first (12.6V).

    Sounds like the battery has given up. How old is the battery?
