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 ?
