The BMW Z4 (E85 roadster/E86 coupe) from 2002-2005 represents a modern interpretation of the classic roadster and introduces a sleek coupe variant. These cars offer a fun and engaging driving experience, but careful maintenance is important to keep them in good condition on NZ roads.
Common issues for the E85/E86 Z4 include coolant leaks (expansion tank, radiator hoses), oil leaks (valve cover gasket, oil filter housing), worn suspension components (especially control arm bushings and ball joints), issues with the electric steering system, and problems with the convertible top mechanism (if applicable). The rear subframe bushings can also wear out. Rust is not typically a major concern but inspecting key spots is always good practice.
WOF tips
During a WOF inspection, prioritize checking brake wear (rotors and pads), tyre condition, suspension components (ball joints, bushings, and springs), lights (including headlight aim), and evidence of fluid leaks (oil, coolant, power steering fluid). Verify that the convertible top (if equipped) operates correctly and that all latches are secure. Ensure the airbags and seatbelts are functioning correctly.
