Bestune B70 Reverse Radar Sensor FC0279120A Parking Assist

For Mercedes-Benz C-, E-, and S-Class owners, if headlights flicker, wipers respond slowly, or the AC behaves erratically, the issue is often oxidation or coil failure in the original relay module with part number A0009824823. This module directly replaces the factory part to control circuit on/off, ensuring stable power to lights, wipers, and AC, applicable to most Mercedes models built after 2000. Replacing resolves intermittent power loss and non-operational equipment.
