S80: Electrical - alarm goes off

keith007 · Sep 14th, 2007, 21:24

hi, new member here, can anyone help? i have an s reg s80se auto, when i set the alarm with the key fob, it goes off at anytime from soon after to hours later. doors, windows etc are all closed and shut ok. it has been said that maybe its the battery not fully charged or slowly dying. has anyone had the same problem?

Fault codes need to be read to point you in the right direction.
Siren faults are quite common also micro switches in the door locks are a known issue.

Had a similar problem on mine and was tracked back to passenger door not being shut firmly - las used by my wife and i never enter the car on that side for obvious reasons. Alarm kept going off at various times after locking and really started to p.i.s.s. me off.

Was shown up on a diagnostic check by my local indpendant. Opened door, slammed it hard shut and the alarm has never gone off since. i suggest you do this with all doors, plus boot and bonnet - will take 2 mins and might work, you never know.

I had a similar problem with my V70, took it to the dealer they read the codes and changed one of the sensors which seemed okay for a short period then it started going off again so I took it back to the dealers who read the codes and I had to have a new siren. So far so good!

have tried slamming doors, boot, and bonnet, no luck. think i will try taking door sensors next and clean them. got to try these things before giving beer tokens to mr volvo, yes.
