Any BMW mechanics/electricians out there? I have a BMW 525i on an 02 that has a faulty alarm - emergency flashers go on, alarm sounds intermittently. At present just lock on key. Have been told alarm is integral to ECU - anyone out there can fix it or give advice? Am in SE London and would be really grateful for help.
A bit of research has pointed out the hood alarm switch by the driver microfilter housing as being a common fault - will try this first as cheaper than 1hr diagnosis by BM! Anyone have any experience - only just bought this for my wife - apart from alarm, nice car!
