The BMW 6 Series (E63 coupe, E64 convertible) made its debut in 2004, setting new standards for luxury and performance in the grand touring segment. With its striking design and high-quality interiors, the 645 Ci is a masterpiece that truly stands out on the roads of New Zealand. Though these cars are relatively rare, they encapsulate a unique driving experience that combines power, elegance, and the thrill of exploration. This overview lays out the essential considerations for owners, especially as they navigate potential maintenance needs.
Common problems echo those of the E60 5 Series, including oil leaks (valve cover, oil filter housing), cooling system failures, electrical issues (iDrive, sensor malfunctions), and suspension wear. Convertible models have additional concerns with the hydraulic roof mechanism.

About the BMW 6 645 Ci
The E63/E64 6 Series not only impresses with its bold aesthetics but also excels in performance with its powerful V8 engines, providing the exhilarating drive that BMW is renowned for. As a vehicle designed for grand touring, the comfort is unparalleled, but as with any high-performance machine, key components require regular attention. Owners should be mindful of specific parts that commonly need replacement, such as brake pads and rotors, especially after reaching 80,000km for a comprehensive service. With the right intervals for maintenance, you can ensure your 645 Ci remains in top shape.
One area worth examining closely is the cooling system, particularly around the 150,000km mark, when parts like the water pump, thermostat, and radiator should be inspected. Addressing these components proactively can save you from more costly repairs down the line – learn more about maintaining your cooling system here.
