S550 Passenger seat belt sensor

I have a 07 S550 and the front passenger seat belt sensor chimes when no one is in the seat. I have recalibrated the seat but this reset only lasts a few days before the problem starts again. How do i permanently fix this problem? Thank you in advance for your help.

To save going through a huge amount of diagnostics and I am thinking here you do not have the test equipment anyway, then go to an car accessory shop and bye a belt buckle clip and insert this into the seat belt catch when no one is using the seat, the computer thinks the belt is fastened and no more chimes.
