The BMW 4 Series (2016-2019) continues BMW's legacy of sporty coupes and convertibles, blending performance with stylish design. It's a popular choice in New Zealand, but understanding potential issues is key to keeping it running smoothly.
• N20/N26 Engine (420i/428i): Timing chain failures are a significant concern. Listen for rattling on start-up, especially when cold. • B48/B58 Engine (430i/440i): Generally more reliable, but check for oil leaks and coolant leaks (B58). • ZF 8HP Transmission: Ensure smooth shifting; service interval around 100,000 km recommended. • Adaptive M Suspension: Prone to failure requiring damper replacement. • Electric Power Steering (EPS): Can experience faults, resulting in inconsistent steering feel. • Convertible Top (Convertible models): Check for leaks and smooth operation of the mechanism. • iDrive System: Check for software glitches and screen malfunctions.
WOF tips
• Lights: All lights must function, including headlights, taillights and indicators. • Tyres: Ensure tyre tread meets minimum requirements. • Brakes: Check brake pad depths, rotor condition. • Suspension: Examine for damaged or leaky dampers. • Steering: No excessive play in steering components. • Windscreen: No cracks or chips in windscreen.
