The BMW E65/E66 7 Series, produced from 2002 to 2008, is not just a vehicle; it's an icon of luxury that transformed the flagship sedan experience. With advanced technology and a striking design, it remains a favorite among discerning owners in New Zealand. Understanding its complexities is key to fully enjoying this engineering marvel.
Common problems on the E65/E66 in NZ include iDrive malfunctions, air suspension failures (leaks, compressor issues), transmission problems (especially with early models), and electrical gremlins throughout the car. Oil leaks from the valve cover gaskets and oil pan are also common. The complex electronics can be expensive to diagnose and repair.
WOF tips
WOF inspectors will scrutinize the lights, brakes (including ABS), suspension (especially air suspension), and overall electrical system. Any warning lights on the dashboard will be grounds for failure. Rust is generally less of an issue than on older BMWs, but any corrosion should be investigated. Ensure the parking brake functions correctly, as this can be a common failure point.
About the BMW 7 730 d
The E65 (standard wheelbase) and E66 (long wheelbase) introduced the iDrive interface, a game-changer in vehicle control, paired with robust V8 and V12 motor options renowned for their smooth power delivery. Owners will want to keep an eye on the air suspension, which generally requires comprehensive inspections and potential maintenance, particularly related to leaks and compressor issues. Regular service intervals, ideally every 15,000 km, can help prevent common pitfalls such as transmission problems and electrical gremlins—especially in the early models.
It's also important to monitor the cooling system, especially around the 150,000 km mark, when components like the water pump, thermostat, and radiator begin to show wear.
