Alarm Randomly Going Off 2005 X5

I got a 2005 X5 and for whatever reason, when i lock the door, the alarm will go off a few minutes later without anyone touching it. The alarm doesnt actually sound because im assuming the sirens dead but the lights flash. Any one else ever have this problem? Any help please?

I had the same problem with my 04'. It happened to be that the battery was slowly dying. This was the only problem I had for a while and then it finally stop starting. At first I was told it was my alternator. I finally just went and had the battery tested at an auto parts store, my luck the guy was familiar with BMW. Check your battery even if everything else seems fine.

I just had a brand new battery put in a few days ago, the blinking seemed to stop for the most part. It didnt blink for a solid 16 hours but when i came home it began blinking after 2 minutes. I also just had a new alternator put in so it isnt that either

What is the status of your DWA (anti-theft alarm siren) system? The red clown nose below the rear view mirror should give you specific indication if there's an issue with a DWA monitor...or if all the monitors are working correctly (see DWA red status LED chart below). If they are (the monitors)...then perhaps the alarm siren's internal battery isn't up to snuff since you were having automotive battery issues.

BTW, does your alarm siren work? Can you hear it if you initiate the PANIC mode (press & hold the tailgate release button)? Do you have the arm/disarm alerts activated & hear the "beep, beep" when you lock the vehicle and the "beep" when you unlock? Has the fuse been removed or the siren unplugged due to false triggering?

(btw..not sure if all face lift X5's have the alarm siren in the location indicated below)

check the hood switch...its located on the passenger side right to the fron of the hood strut...its a pushbutton type....to troubleshoot it..

just disconnect the wire from it....close the hood....activate the alarm and wait to see what happens

if it stops going off then you have a bad hood switch....very commone failure in the e39s...this truck uses the same switch...

ive had this problem on the 540 and the x5 ...replacing the switch fixed both
