my alarm keeps going off in the middle of the night for no reason .any ideas ???unlocking then locking again solves the problem for a couple of hours .
the car is parked on level ground no windows or sunroof are open .
is there a sensitivity control for the alarm ??? It is factory fitted and i dont want to take it to the dealer as they are tooo expensive .

ps is there a good online v50 manual ???? Thanks guys Cheers

I had a similar problem.
there is no any workaround for this alarm reseting or diasabling.

Hi -- had that problem on my previous V50 (2006 model). There is a small sensor that was updated on the 2007 model, your dealer knows about it and will identify it for you.

Mine was setting off the alarm at 5:10 in the morning ... every morning ... not at 5am, not at 5:30 am, never by day, just at 5:10.

I now have a 2007 model of the same car, and all the "niggles" of the 2006 models have been addressed.

tHANKS FOR THE INFO ABOUT THE SENSOR I WILL ASK MY DEALER ABOUT THAT
CHEERS :)

I agree with the sensor solution - my 2005 V50 did the same. It would pick its time (say, 11.50pm) and trigger at that time for a couple of days, then go quiet for a few weeks, then pick another time! Amazing, if it wasn't so annoying!

Anyway, a new sensor was fitted and, so far, no problems after 1 month. Gooood luck!
