The BMW E39 5 Series is where timeless elegance meets contemporary engineering, a beauty that remains a head-turner on New Zealand roads. With a legacy enriched by devoted owners, the E39 celebrates its high-quality build and advanced technology, balancing performance with comfort. As a beloved classic, it deserves the best care to keep it performing at its best. Let’s explore why this vehicle is a standout choice for Kiwis, and how to ensure it stays that way.
Typical issues include cooling system failures (radiator, water pump, thermostat), VANOS problems (variable valve timing, especially on the six-cylinder engines leading to rough running), oil leaks (valve cover gasket, oil filter housing), suspension wear (especially front control arms and bushings), and pixel loss in the instrument cluster and radio display. Rust can also be a concern, particularly around the door sills, wheel arches, and underbody. Electric windows can also fail, due to the plastic clips degrading.
WOF tips
Pay close attention to suspension components (check for play in ball joints and bushings), brake lines (corrosion), and headlight alignment (clouding can affect beam pattern). Oil leaks are a common reason for WOF failures. Ensure rust is addressed promptly. Also, check that all lights (including fog lights and indicators) are functioning correctly. A broken indicator lens is another common WOF failure at the time of testing.
About the BMW 5 520 i
The E39 5 Series is renowned for its perfect blend of sporty handling, comfort, and exemplary build quality. The smooth inline-six engines deliver power seamlessly, while the optional V8 variants add an exciting edge to your driving experience. Inside, the driver-focused cockpit envelops you in luxury, making every drive pleasurable. Since the E39 has hit the roads for over two decades now, regular maintenance is crucial to preserving your investment.
Be sure to keep an eye on the cooling system, especially as you approach 150,000km—critical components like the water pump, thermostat, and radiator should be thoroughly inspected to avoid overheating issues. If you’re experiencing performance dips related to the VANOS (variable valve timing), we recommend a look at the timing components as well. Addressing oil leaks around the valve cover gasket and oil filter housing will also help maintain its superb performance. Don't forget, wear and tear on the suspension—like front control arms and bushings—can affect your ride comfort.
