Maintenance/Repairs

I have a 97 BMW 528i with 222,000 miles. In the last 3 weeks, while driving down the road, the Hazard Lights come on, the overhead light comes on. Then when I stop the car, get out, and try to lock the doors, the doors will not lock the first time the door lock is depressed. The alarm goes on, but the door locks are not engaged. So I must unlock the doors which aren’t locked, and then lock them again. At which point the doors lock and the alarm is reset. Another piece of information is that my battery died 3 weeks ago, the first time this happened. I took the battery in and they said I had a bad cell in the battery. So I replaced. After the battery was replaced, I took it the SRS airbag light came on. So everything seem ok, other than the airbag light for a week. Then the lights started again. One week later, my battery was dead. So I charged the battery and went back to Autozone, my alternator is working and the battery was charging. I also, cleaned the battery contacts prior to going to Autozone. I don’t know if this helped or not. Anyway, I decided to take the car to my mechanic and they found nothing wrong with the car, other than the oil temperature sensor which they replaced and said possibly could cause this problem. Not the SRS airbag light, that problem they said is because the SRS control module is shot. So now a week later, after replacing the oil temperature sensor, the hazard and overhead lights are still coming on when driving down the road. The next step I was going to try was to lock the doors and see if the doors become unlocked while driving down the road, which might point to the crash sensor relay or fuse. However, I don’t know if this problem will cause my battery to drain again or if it was unrelated. I could use some help.
