Front Air Bag Sensor Control problems of the 2007 Mini Cooper S

Passenger seat mat occupancy sensor/pad has gone bad again after the recall.

Passenger airbag deactivates itself while an adult passenger is riding in car. The car does this at random. Dealership has checked the car and says that it is working properly.

Passenger airbag sensor does not sense passenger. Light illuminates stating passenger airbags off. Dealer has replaced sensor seat mat twice and still does has not fixed the problem. After the last fix the Mini tech service advisor sent home with me adding a statement to my file that if you are a certain size/weight and or move in seat light could come on. I do not move around in seat and I my size is not the issue. Is currently at dealer since I had to go through BMW to get a rep to look at. As of today car is not fixed. There were problems with these as told to me by the service advisor and parts manager at BMW and my first seat mat I had to wait 3 months for because of backorder and availability since so many were wrong. My number is large in the # of failures category since everytime I get in the car it takes about 3 -6 failures before I can trigger it to work since may 2007 which is when I bought the car new.
