Alarm fault

[millerman1ac]

Had my alarm go off the other night sitting outside the house first time i've had this!
went out in a hurry thinking someone maybe at it!! No one there so turned it off and checked all the doors, boot etc
reset it and went back in, 1 o'clock in the morning alarm goes off again wakes me up, i check car again all ok so just leave it unlocked all night as im in a quiet area....
in the morning it's still there so all good, take it into work to check it out and alarm goes off again just sitting there so i went through a process off elimination and work it is the switch for the bonnet. Try giving it a wee blast of WD40 but didn't help..

So i just unclip the connector and it works alarm stops going off!!
has anyone else had this problem?
Im thinking it's just maybe the cold damp weather getting into the switch?

i'm hoping to get to BMW dealer today to see if i can pick up a new switch, wonder what they cost!!??

there was a topic on this recently, search the threads, they are cheap, was either £7 or £14 but no more than that. and yes these switches are renowned

Hi

Sorry bit off thread but I saw this the other day and have never tried it and often wondered if it worked as far as the alarm is concerned.

33. If you want to leave your windows down but have the alarm set, but not have to worry about the motion detector go off, you can arm you alarm by hitting the lock button, and then wait a second and hit the button again. You'll see the clown nose light up for a second, which means the motion detector is deactivated

I know it sounds like your sensor but this may help people if indeed it works !!!

yes this does work Penny pressing the lock button twice deactivates the motion sensors that's how i new mine was the bonnet sensor as the alarm wen't off when it was deactivated.

Had this random alarm fault in my old X- it was the bonnet sensor, I just put a felt pad directly above it on the inside of the bonnet and it cured it

Motion sensor defeat method good for ferries to prevent your car alarm going off the whole crossing!
