Air Bag On-off Switch problems of the 2009 Mercedes Benz C350

"takata recall" there are two recalls on the front airbags one issues in February 11, 2016 and the other may 25, 2016. I've taken my car in several times for service and inquired about the recall. As of today the remedy is not available. There is a fault switch with the headlights in off position the left right turn signal flash when the keys are not in the vehicle. It drains the battery which have replaced twice. We determined that if we keep the light switch in automatic position it does not happen.
