Hazard light madness

[Hasey]

I'm new to the world of Bimmers and just got my first one yesterday although not new, I've just bought a 1998 318 TDS Touring and when I park it up and lock it sometime after the hazard lights start to flash, If I unlock the car using the keyfob they stop if I unlock using the door lock they remain on, also there's a red light on the front of the center console that flashes on and off with the hazzards. I'm guessing it's something to do with the alarm although the siren isn't sounding. Any ideas? It's got me baffled and stops me leaving the car anywhere for a prolonged amount of time as it will probably drain the battery, I don't want to have to start disconnecting the battery everytime I park up, I've just got rid of my last car because of that, please help.

OK tried disconecting the bonnet tamper switch, didn't work, tried adjusting it up for a better contact, didn't work. Had a few days of it not happening and now it's doing it again, about 6 times tonight upto now, it's driving me mental. Is there anything else it maight be? Does it have an alarm? No siren sounds but it may have been disconnected, I don't know. I do know I really need help with this.

A 1998 should have a factory alarm. Te siren is located behind the drivers headlight but a little lower down. The alarm module is located behind the glovebox. Their should also be a hood switch on the passenger side halfway up in the engine bay. Behind the washer fluid reservoir usually.
