Can anyone help. I brought the 2001 v70 two months ago, checked out the alarm all was OK, siren worked and everything. This morning got in the car and the red LED on the dash was flashing quickly, when I put the key in and turned it I got a message "Alarm been activated, check car" There was no sign of a problem. The car ran fine, Later this morning I used the car again, this time got the message "Alarm system requires a service" I had this message every time I started the engine, it went out after a few seconds.
When I got home I checked the codes, there wasn't any showing. I tried to check the alarm system by activating it while inside, no siren, also opening the bonnet, again no siren.
My question is it the alarm battery or the siren at fault or could it be something else? I was quoted by the stealers £130 for the unit + £31.50 labour + VAT
