At about 1 am in the morning the X's alarm started going off. After the second time it reset and went off again. I rush out there and see nothing.
I get in the X. start it and drive off. Immediately the door open alert comes accross the dash. I'm like hmm so my doors open. I check all doors and not a single door or trunklid is opening. Im going crazy now i get out and slam shut all 4 doors the dash is is saying door open still. I noticed the central locking is not working either. Its locking but not unlocking. I then figured maybe its a fuse. I pull the central locking fuses in the rear. THAT DIDNT fix it. I couldnt get the back lid open. Next i pulled the central locking fuses up front 20,24, and 60. this allowed me to lock the door manually via key. But only the drivers door can be locked. That allowed me to go to bed with the x locked but without the alarm armed. I drove to work and after every complete stop i got the same error door open.
Does anyone have a way of troubleshooting this. I would love to find out what door is causing the fault. But all it says is door open. Would disconnecting the battery for 15 mins reset the computer and possibly fix my door open issue. or Move my steering wheel from 1 side to the other side in position 1?
History- we had some bad rain earlier that day. I parked my car and that was it. no indication it was a door fault. and I only had opened my driver door and rear driver side door.
Is there a sensor i can bypass. I know on other cars its just a trigger on the door with a switch i could just short or break the circuit. On this X5 i have no clue where to look. Im not even sure what to search on here.
thanks for looking
