No, none of this makes sense. Only thing over on the right side of the trunk is the battery. That's the only thing that I can think of over on that side anyways. This symptom I've never heard of before, at least not any description that sounds similar to this. As far as the battery-draining mode being part of the anti-theft system, no, not happening like that. I can't think right now where the power lock vacuum pump is, maybe it's something to do with that. Try to really find what is making the noise. As far as trying to do any remote diagnosis, I'm stumped until you can actually put your hands on the source.....Gilly
