Hazard lights keep flashing + battery drain

Recently I have been having the following issue with my daughter's 9199 323i which otherwise works great. Every so often when the car is parked it would start flashing its hazard lights, same lights that flash when we lock or unlock the car, and would keep flashing for sometime. It does not make a difference if the car is locked or unlocked. Also the battery keeps draining every few days. I bought a brand new battery but that did not fix the problem. The battery keeps draining and the car keeps flashing. Not sure if the the two issues are related. Somebody suggested to me that it may be a problem with one of the crash sensors which would explain the flashing. Any idea/suggestion would be greatly appreciated. By the way where is each of the crash sensors located on the E46?

Thanks in advance
