The BMW 6 Series (F12/F13/F06) from 2012-2017 is a stunning representation of luxury and performance, uniquely tailored for those who appreciate both style and driving engagement. Renowned across New Zealand, the 650i stands out for its combination of advanced engineering and driver-centric technology, offering an extraordinary ownership experience. This grand tourer, with its meticulously crafted interiors and impressive performance characteristics, requires thoughtful maintenance to uphold the very qualities that make it desirable.
Common issues include oil leaks (valve cover gaskets, oil filter housing), coolant leaks (especially with the N63 V8), electrical gremlins (sensor failures, iDrive malfunctions), and wear and tear on suspension components (control arms, bushings). The direct injection engines are prone to carbon buildup, potentially affecting performance. Turbocharger issues can also arise on models equipped with forced induction.
Pay close attention to tyre condition (due to the car's weight and performance potential), brake performance (ensure even wear and sufficient pad thickness), and the functionality of all lights (including adaptive headlights, if equipped). Suspension components must be in good order, with no excessive play or leaks from dampers. Windscreen condition is also vital, particularly lower windscreen corners and wiper operation as the windscreen curvature leads to inconsistent wear and wiper performance.
The 6 Series is available with an array of powerful engines, highlighted by the captivating V8 of the 650i. While it boasts capabilities that excite, it also presents owners with specific maintenance considerations. Commonly, you may encounter issues such as oil leaks from the valve cover gaskets and oil filter housing. Keeping an eye on coolant integrity is crucial, particularly in the N63 V8, which is known for coolant leaks that can lead to more significant problems if left unaddressed. Regular servicing intervals — especially for cooling system components like the water pump, thermostat, and radiator hoses — should ideally occur around 150,000 km. By ensuring these parts are checked and replaced as necessary, owners can protect their investment and enhance performance. Don’t overlook the importance of adapting to changing conditions; suspension components and brake systems should also be inspected regularly.

With diligent upkeep and the right parts, you can continue to enjoy what makes the 650i an unparalleled driving experience.
