04 XC90 2.5T 185K. Driving down the road lately, and the "Driver Door Open" warning starts going off, dome lights on. However, the door is closed! Also, occasionally, the alarm is activated while parked. Any possibilities? Door Latch Mech? The dealer says, and I quote "bring it in, it could be the computer or maybe a kinked wire, or a little switch" (those were their exact words!). Hmmm. Thought I'd ask here before getting raped at the dealer for a computer.

 

Sounds like your for lock assembly is going bad. The dealer was just naming things that it could be not things they want to "rape" you on

 

I saw your post and I am having the same problems. Did you ever get yours fixed and if so, what was the problem?

 

My 2005 S40 T5 had a problem with the alarm going off sitting in my driveway. I finally removed the alarm for the time being. Then it would randomly flash the emergency lights. Then the door open and interior lights would come on. I would lock and unlock the doors off and on and the door warning would go away and the interior lights would go out. I have some time to look into problem butI was wondering if anyone had any suggestions where to start. I think it is possibly a switch on the door latch. Help Please!
