    Evening all, I have a 2006, 325i (E92), that throws up an intermittant warning sign of an open bonnet. I have replaced the under bonnet switch thinking that may be the cause, but it still happens.
    There is a pattern developing though, it only seems to happen when going downhill or braking hard. The open bonnet warning light (and bleep) only comes on for a second, then disappears. The car is running perfectly otherwise. I am suspecting water ingress somewhere throwing up the error, but where does one start to investigate ?
    Is there anyone out there with experience or knowledge of this silly annoying glitch ?

    Tape your switch down and then drive around to confirm. Could be your bonnet closure needs adjusting.

    Well, tried taping down the switch, but problem still occurs. Still intermittant and still only flashes up for a second or so.
    Car is going in for an oil service soon. I'll get the garage to look for any fault codes that may have been recorded.

    The intermittant warning light and bleep stopped for a week or so, only to be replaced by an intermittant bulb failure warning and bleep.
    Finally tracked it all down to a rear brake bulb. After removing the light clusters and all the bulbs, I noticed that the (flimsy) bulb connection wire was actually corroded.
    My bulb was the capless variety where the contacts are small bent wires at the base of the bulb.
    Bulb replaced and all is now OK.
    Could the dodgy electrical contact on this bulb have caused the warning system to get confused ?
    The wonder of electronics !!!!
