The rubber accordion tube between the driver’s door and the A-pillar contains dozens of wires. Repeated opening/closing of the door fatigues the copper strands. The LIN bus wire (often white/grey or yellow/black) breaks internally while the insulation remains intact. This is a classic Mercedes-Benz issue on higher-mileage vehicles. | Repair Type | Independent Shop | Mercedes-Benz
