The BMW 6 Series (E63/E64) from 2005-2010 is a remarkable grand tourer that fuses luxury with high performance, offering drivers a compelling experience on every journey. Available as both a coupe and convertible, it radiates elegance while ensuring incredible road presence. However, owning this exceptional vehicle means being proactive about maintenance, as repair costs can be higher than those of more common cars. Here, we outline some key areas to focus on to maintain your 650i and enjoy uninterrupted driving pleasure.
iDrive malfunctions, air suspension failure (leaks), coolant leaks (especially around the valley pan under the intake manifold), oil leaks (valve cover gaskets, oil filter housing), transmission issues (especially with high mileage), electronic gremlins (sensor failures, control module issues), soft top mechanism failures (convertible), and general wear and tear on suspension components.
Check for excessive oil leaks and coolant leaks. Ensure all lights function correctly. Pay attention to tyre condition and tread depth, and examine the brakes for wear. The air suspension must function correctly and maintain ride height. For convertibles, inspect the soft top for damage, leaks, and proper operation.
The BMW 6 Series artfully combines stunning performance with the comforts of a grand tourer. With powerful engine options like the 4.8L V8 in the 650i, it delivers exhilarating performance while maintaining the refinement expected from BMW. However, regular servicing is essential to avoid complications. One area of concern is the cooling system, which typically requires attention around 150,000 km. At this interval, it’s wise to inspect vital components such as the water pump, thermostat, and radiator hoses. Proper maintenance in this area helps prevent overheating issues and is a crucial step in safeguarding your vehicle's performance. Explore our Cooling service options here.
Additionally, the 650i may experience iDrive malfunctions, a common issue with many BMWs of this era. Regular software updates and diagnostic checks can mitigate potential malfunctions. Moreover, keep an eye on the air suspension, particularly in convertible models, as leaks can compromise comfort and handling. By incorporating systematic checks for parts like brake pads and rotors, particularly during service intervals, you can enhance your safety on the road. Not to forget, proactive maintenance of filtration systems, including oil and air filters, every 10,000 to 15,000 km ensures your engine runs smoothly.
