hi the most common problem is the siren located on the o/s inner wing and the code stored will be uem004 siren internal fault
if you replace it you will have to have the new siren config to the uem of the by a volvo dealer
hope this helps

I don't know if this will help I have a 2002 v70 xc wagon. The window rear passenger was damaged from weed waker and chipped glass. I had it replaced $450.00 Volvo window. They could not get button to go up and down now actuator is on order. Any way. They pulled the positive battery terminal thinking it would reset door locks. No good. Then the dreaded Alarm Sysytem Service came on, I only had visible alarm ( all four lights flashing, Headlights and tail lights) No Audible alarm. After searching on internet. I disconnected battery positive onlys again. Waitied 10 minutes. Put it back on (cable) and put the key in the ignition and turned key and then turned it off. Got out of the car and hit lock and unlock with remote . Now all is fine. I think removing the cable resets the computer module in car and resets everything. The key in the ignition I think resets the code for alarms. Anyway it worked hope it does for you. Sorry this is long.
Disconnect positive battery
Wait 10 minutes
Turn ignition on then off.
Get out and lock and unlock car with remote/door lock.
Arm alarm and test.
Good luck...
