    Hi,

    there is a problem of alarm in my car. When i use the remote key to lock the door. After a few hours or an hours, the alarm will automatically on with beep beep sound, indicator lamp also comes on flashing.

    i have a Launch Diagnosis for check on the car. when i see the actual values, the bonnet switch, doors, boot lid. those all closed completely.

    but it stayed a only one fault code on the DWA system, "8A DWA alarm memory:passenger-comp. sensor, front". i cleared the fault everytime. But this fault code which is happen again after the alarm suddenly on.

    I am sure there is no fault on the bonnet switch and rear boot lid lock. Does anyone knows the problem? Where is the location of "Passenger-comp. sensor, front"?

    Thank You.

    You need to turn off the interior sensors and then see what happens. To do this, arm the car pressing the button on the fob once and then immediately press the button again. This will switch off the interior sensors and the clown nose will acknowledge this command by staying lit for a few seconds before going into the usual blink mode.

    Going slightly off topic I know, but instead of disconnecting the bonnet switch you can pull it up and it clicks into a 'service' position simulating a closed bonnet..

    I too have been suffering from spurious alarms when everything is quiet, today i had time to search some previous post, i removed the bonnet switch plug from the switch, fingers X'd all seems ok now, many thanks for this tip, would have cost a bit taking it to my dealer

    I will find out how much a new switch cost, bet it won't be cheap??

    I stand amazed, new genuine BMW switch from Woods in Odiham costs £10 inc VAT, bargain or what!

    Sounds like your interior sensors, especially if your diag machines not picking up switches as okay.

    I have a M3 and when I set the alarm using the buttons on the key it still goes off, sometimes after 5 minutes, sometimes after half an hour, etc.

    I have read the manual, and pressed the button on the key twice like it says to de-activate the interior alarm but this still doesn't work.

    So I now lock the car manually by turning the key twice as it says in the book, but today I forgot and as I returned to the car after an hour sure enough the alarm is going off!

    The car is a 2006 model.

    Any suggestions please.
