Recently I had the dash out to replace the blower motor, all went fine, but after a few days the airbag light on the instrument cluster came on. Have disconnected the battery and checked the connector on the passenger airbag - Ok and reconnected the battery. Light remails on. Don't have a code reader that will read BMW enhanced codes.
Suggestions?
