The BMW Z4 (E85/E86) from 2006-2008 represents a sweet spot for stylish roadsters and coupes, blending iconic BMW handling with open-air driving enjoyment. In New Zealand, these models offer a taste of European performance at a relatively accessible price point. However, like all vehicles, they have their quirks and areas that require careful attention, particularly considering their age and the demanding NZ driving conditions.
Common issues across this generation Z4 include: Oil leaks: Valve cover gaskets and oil filter housing gaskets are notorious for leaking as they age. Cooling System: The cooling system, including the water pump and radiator, can become brittle and prone to leaks. VANOS Solenoids: These can cause performance issues and trigger fault codes. Convertible Top (Roadster): The hydraulic system for the convertible top can experience leaks or failure. Electronic Issues: Sensor failures (e.g., oxygen sensors) and electrical gremlins can occur. The electronic steering lock can also fail.
WOF tips
When taking your Z4 for a WOF, pay close attention to: Tyres: Ensure adequate tread depth and even wear, especially critical given the car's sporty handling. Brakes: Check for sufficient brake pad thickness and inspect rotors for wear or damage. Brake lines should be free of corrosion. Suspension: Inspect shocks, springs, and bushings for wear or damage, as this affects handling and safety. Ball joints and suspension arms are also common WOF failure points. Lights: All lights must be functioning correctly and properly aligned. Rust: Check for rust, particularly around the underside and wheel wells. Fluid Leaks: Any significant fluid leaks will result in a WOF failure.
