The BMW 5 Series made waves upon its launch in 1972, establishing a captivating blend of sporty dynamics and refined comfort. From 1975 to 1976, the E12 generation emerged as a benchmark for executive sedans, capturing the hearts of drivers who sought a thrilling yet sensible ride. Today, these early models stand as cherished classics, embodying a piece of BMW's rich heritage. For the discerning Kiwi driver, possessing an E12 is not merely about owning a vehicle; it’s about preserving a legacy steeped in style and performance, necessitating dedicated maintenance to keep these beloved cars running smoothly.
Common issues include rust (especially around the wheel arches, sills, and suspension mounting points), worn suspension components (bushes, ball joints), oil leaks (particularly from the valve cover gasket and rear main seal), and electrical problems due to aging wiring. Carburettor issues on these early models can lead to poor running and emissions failures.
When taking your E12 5 Series for a WOF, pay close attention to the following for a 1975 - 1976 model: Rust: Any structural rust is an immediate failure. Suspension: Worn bushes and ball joints are common. Brakes: Ensure the brakes are functioning correctly and that the brake lines are in good condition. Lights: All lights must be working properly and correctly aligned. Tyres: Tyres must meet minimum tread depth requirements. Exhaust: The exhaust system must be leak-free and securely mounted. Steering: Excessive play in the steering is a failure point.
The E12 5 Series offered a variety of robust inline-four and inline-six engines, prized for their performance and reliability. That iconic 'shark nose' front end, easily identifiable, draws attention wherever you take it. However, potential issues related to carburettor and early fuel injection systems can arise over time, especially in models over 40 years old. Regular service intervals are vital; owners should pay close attention to the cooling system around 150,000 km, ensuring that the water pump, thermostat, and radiator hoses are inspected and replaced as necessary.
