could be ultrasound sensor things

very sensitive to temperature drops. Same happens on my C280. Only solution is to disarm them.

My only suggestion is to get up before the time and keep close watch. Its a bit early for a newspaper boy that likes setting off car alarms.
Sometimes alarms can get triggered by very low frequency vibrations, like for example if you live on an aircraft flight path or are directly over an underground railway. Another possibility is that a Halfords Corsa goes past your car with subs at full whack. :roll:
