2014 BMW 640 3.0L Diesel · MS08 LEE

The most recent MOT test on the 2014 BMW 640, conducted on 2026-05-07, resulted in a passing grade with two advisories: the offside front tyre is worn close to the legal limit and exhibits edge wear, while the near-side front suspension arm pin or bush shows signs of wear but does not yet cause excessive movement affecting the lower shock mount. This follows a failed MOT from the same date, where two dangerous failures were recorded concerning the near-side and offside rear tyres having insufficient tread depth, alongside the same advisories. Comparing the test history, the vehicle’s maintenance trend appears to be inconsistent rather than improving or worsening, with repeated tyre-related issues and recurring suspension advisories suggesting ongoing wear that requires attention. The presence of multiple advisories in recent years indicates that while the vehicle remains roadworthy, it has not yet reached a critical failure point but demands proactive maintenance to prevent escalation. The recorded mileage of 100,278 miles for a vehicle aged approximately 12 years represents a moderate annual usage rate of around 8,356 miles per year, which is typical for its class and age. This usage profile suggests a combination of regular driving and periods of inactivity, which can lead to specific wear patterns. Lower mileage could indicate reduced consumption of consumables like brake pads, clutch components, and fluids, but standing the vehicle for extended periods can accelerate corrosion in brake systems, particularly on the near-side front brake discs, where binding or corrosion is a known risk. Conversely, higher mileage would imply more aggressive wear on suspension components, drivetrain elements, and tyre tread, necessitating closer inspection of these areas. The suspension advisories, particularly those related to arm bushings, also align with typical wear progression in a high-mileage vehicle, warranting a thorough examination of the entire suspension geometry and alignment. For the prospective buyer, the most critical areas to inspect are the tyres, suspension, and brakes, given the recurring advisories and failures observed in the MOT history. Begin with the tyres, checking for the offside front tyre’s edge wear and potential cracking, which can indicate uneven load distribution or alignment issues. On a test drive, listen for signs of uneven tyre wear, such as clunking noises from one side or a noticeable difference in handling response, which may suggest misalignment or suspension component failure. The near-side rear tyres, which failed the MOT due to insufficient tread depth, should be replaced immediately, as tread depth below 1.6mm is a dangerous failure and poses a significant risk of hydroplaning. Additionally, inspect the front tyres for cuts or debris that could indicate underlying tyre damage, and ensure they are not perishing from age, particularly along the sidewall, where flexing can accelerate cracking. The suspension system, particularly the front suspension arm bushings and lower shock mounts, should be thoroughly examined for signs of excessive play or wear. On the test drive, pay attention to any clunking or rattling noises from the suspension, especially when driving over bumps or at speed, which may indicate worn or failing bushings. Visually inspect the suspension components for oil stains or signs of leakage, and check for uneven coil spring compression or sagging, which can signal spring failure or misalignment. The near-side front suspension advisory suggests that the pin or bush in the lower control arm may require attention, and further deterioration could lead to excessive movement or even detachment, compromising steering stability. Finally, address the front windscreen wiper advisory from the 2023 MOT, replacing the wiper blade if it no longer clears the screen effectively, as poor visibility is a safety hazard. Beyond these immediate concerns, consider a comprehensive inspection of the brake system, including checking for corrosion on the near-side front brake discs and ensuring the calipers are not binding, as prolonged standing can lead to rusting and reduced braking performance. Additionally, verify the 12V battery health, as older vehicles can suffer from reduced capacity or internal corrosion, and check for signs of fluid degradation in the engine oil, differential fluid, and brake fluid, which should be serviced according to the manufacturer’s recommendations—typically every 60,000 to 100,000 miles or every 2 to 5 years, depending on the fluid type.
