This 2011 BMW 6 Series 640i Convertible was first registered in June 2014 and currently has 76,000 kilometers on the odometer. Features include ISOFIX child seat anchors, keyless start, paddle shifters, Bluetooth/hands-free calling, and adaptive headlights. The exterior is in excellent condition, the engine and transmission are running smoothly, and the car is in superb condition, offering exceptional value. Welcome to visit our dealership and experience it for yourself!
It does not affect basic driving and regular speed cruise, but it will trigger a fault alert for advanced driver assistance on the dashboard. The LiDAR assembly is extremely expensive, so we focus on checking the integrity of the glass cover with a strong flashlight during inspections.
Most basic maintenance reminder lights (like for changing the air conditioning filter) can be manually cleared using a combination of steering wheel buttons or through the engineering mode on the central control screen. We will provide internal guidance manuals for these hidden operations to our B2B clients.
We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
