Hi, this is my first time responding. Not sure if your problem is sorted. I have a 63 plate RS CLIO Sport. Mine started with the alarm going off at all times of the day. Sensors were checked, battery too. Nothing found. Did all the recommended disconnect, deactivate interior alarm. Was driving work & neighbours mad! Now, all of a sudden, my sat nav has gone down- no maps found, but upside…. No alarm going off! Only issue is, no garage will touch my car as I’ve been told this morning ‘ needle in a haystack?’ I don’t know where to turn. That’s from an electrical point of view.
