It's crucial to address airbag issues promptly due to safety concerns. The airbag control unit in your BMW 335i GT is typically located under the center console or beneath the dashboard. Given the coding changes and inability to access the control unit, it's possible the unit is malfunctioning. Before considering replacement, check all related fuses and wiring connections for any loose or damaged parts. If these are intact, consulting a specialized repair shop for the control unit might be worthwhile. Please update on your progress or if you have further questions.
