BMW 5 Series 530d.
What to Check Before Buying.

The BMW 5 Series 530d suits company car drivers and high-mileage motorists seeking a blend of performance and efficiency. This 3.0-litre diesel engine delivers strong acceleration alongside impressive fuel economy, typically achieving 45-55 mpg in real-world driving. The 530d provides ample power for motorway cruising while keeping running costs reasonable for a car of this size. However, potential buyers should be aware that the diesel particulate filter can cause issues if the car has primarily been used for short urban journeys. When inspecting a used 530d, check the service history meticulously for evidence of regular oil changes using the correct BMW Longlife specification, as this engine is sensitive to poor maintenance. Listen for any unusual noises from the timing chain, particularly on higher-mileage examples built before 2015. Verify that the DPF regenerates properly during a test drive and inspect for any warning lights related to emissions systems. A comprehensive Folt vehicle check can reveal the car's mileage history and help confirm whether it has been motorway-driven or used predominantly for shorter trips.
