Alarm module 8637399

azzledazzle · May 9th, 2023, 13:04

As the title suggests, looking for an alarm module. Current one is kaput and can't be fixed, alarm service message is annoying me every time I turn the car on, but not annoying me enough to pay £200ish for a new one from Volvo.... (Yet!)

Thanks.

Managed to source one from a nice chap on the xc90 owners Facebook group. £50 posted next day delivery. Works a treat. No more warning message on the dash. Quite the bargain to be fair as I hadn't found one on fleabay for less than £100.

change the battery or you will go back to the alarm message the life of these battery's is abt 6/7 years what year car was your replacement sourced from? to try and gauge how much life it has left. i cut open at least 9 alarms before i found a salvageable one replacement battery's are available on ebay

I replaced the battery on my old unit but that didn't help. The original battery was fine also, still pushing out 7v and hadn't leaked everywhere.

I did put the new battery from the old unit into the replacement unit before I fitted it yesterday as I am not sure what year it came from, so hopefully it'll remain functional for as long as I own the car.
