I have a 2012 astra j estate with an alarm issue which is activating on a regular basis when locked but not reporting any fault codes in the bcm so rather than find the fault i was hoping to configure it out of the bcm using opel gds but I don't see any options available to do this,hoping someone with gds experience could advise me on how to get into bcm configuration menu or recommend any other tool which will do this

thanks
