Introducing the BMW 6 Series (E24), affectionately dubbed the 'sharknose'; an iconic coupe that seamlessly blends elegant styling with exhilarating performance. Its timeless design and exhilarating driving dynamics have garnered a loyal following across the globe, including New Zealand, where enthusiasts continue to celebrate this masterpiece of automotive engineering.
Common issues found in the 1977-1989 BMW 6 Series include rust (wheel arches, sills, around windows), fuel system problems (injectors, fuel pumps), suspension wear (especially rear self-leveling systems), and electrical gremlins. Also look out for power steering leaks and brake system malfunctions. The complex electronics of the era can be challenging to diagnose and repair.
During a WOF check, pay close attention to rust on structural areas, the functionality of the lighting system, tyre condition, brake performance (including hoses and master cylinder), steering play and component integrity, and suspension condition (shocks and bushes). Exhaust emissions and system integrity will also be examined.
This era of the BMW 6 Series delivers a distinctly classic driving experience, characterized by smooth power delivery and responsive handling. The 635 CSi, a standout within this lineup, showcases a finely-tuned suspension and a powerful engine that invites spirited driving. However, with vehicles of this age, maintaining performance is crucial. Common issues to watch for include rust, particularly around wheel arches and sills, which can be detrimental to the chassis integrity.
As a guide, regular service intervals are pivotal. Pay attention specifically to the cooling system; it's recommended to inspect the water pump, thermostat, and radiator around the 150,000 km mark to prevent overheating. This naturally connects to our Cooling category where you can find essential parts. Additionally, brake components are vital for safety—front and rear brake services can help maintain optimal stopping power. Look to our Braking category for reliable replacement parts. The fuel system, including injectors and fuel pumps, often requires attention; in fact, a regular inspection can save you from future headaches. Don't forget—proper filtration is key too; check our Filtration products to keep your engine running smoothly. Taking these proactive steps ensures you can continue enjoying the exhilarating drive that the 635 CSi promises.
