Experience the epitome of luxury with the BMW 7 Series (E65/E66), produced from 2005 to 2008. Recognised for its bold 'Bangle Butt' styling and advanced technology, this flagship sedan offers a dynamic driving experience paired with remarkable comfort. As a discerning owner, understanding the intricacies of this model will ensure you maintain its grace and performance on New Zealand's winding roads. Let’s delve into how you can keep your 7 Series performing at its peak.
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), and general wear and tear on suspension components.
Check for excessive oil leaks as these are common and a WOF failure point. Ensure all lights (including indicators, brake lights, and headlights) are operational, as electrical issues are frequent. Pay close attention to tyre condition and tread depth, and examine the brakes for wear. The air suspension must function correctly and maintain ride height – sagging indicates a problem. Check electronic park brake functionality.
The 730i, Li boasts a selection of powerful petrol engines, providing vibrancy and smoothness behind the wheel. However, to keep this luxurious sedan running smoothly, it's essential to address common issues that may arise. Notably, the iDrive system, while revolutionary, can be prone to malfunctions as it ages. Regular servicing, particularly around the 100,000km mark, is crucial for the longevity of key components like the air suspension and electronics. In fact, air suspension specifically can fail due to leaks on New Zealand's rugged roads, prompting timely inspections of the system. Parts such as water pumps, thermostats, and radiator hoses require special attention, particularly around 150,000km, linking directly to our cooling system service offerings. Additionally, routine brake service is imperative; the front and rear brakes essential for safety and optimal performance need to be checked frequently.
