2020 BMW F750 0.9L Petrol · WN70 FMP

The most recent MOT test for the 2020 BMW F750 was conducted on 2025-12-19, resulting in a passing outcome with a single advisory related to the rear brake system. This advisory, classified under 1.2.1(e), indicates a slight fluctuation in brake effort, which suggests a minor irregularity in the hydraulic or mechanical balance of the rear braking circuit. While the vehicle has passed subsequent MOTs without further defects, this recurring advisory—particularly when appearing in the most recent test—demands attention. Such a condition could stem from issues such as binding calipers, uneven brake pad thickness, or a failing brake servo, all of which may lead to inconsistent braking performance or increased wear if left unresolved. A test drive should include a thorough inspection of brake pedal feel, checking for any sponginess, pulsation, or uneven stopping distances across the rear wheels. If the fluctuation persists, further diagnostic work may be required, potentially involving brake fluid analysis or hydraulic system recalibration. The recorded mileage of 2,660 miles for a vehicle aged six years represents an exceptionally low annual usage rate of approximately 443 miles per year. This is far below the typical driving patterns of comparable luxury vehicles, which often accumulate 10,000 to 20,000 miles annually under normal conditions. The disparity between the vehicle’s age and mileage suggests either prolonged periods of inactivity, infrequent use, or potential misuse—such as excessive idling or towing, which could accelerate wear on critical components. However, the low mileage does not inherently guarantee the vehicle is in pristine condition, as prolonged standing can exacerbate issues like corrosion, particularly in the brake systems, suspension, and exhaust components. The advisory from the latest MOT highlights the need to monitor the rear brakes closely, as standing vehicles are prone to brake disc corrosion or caliper binding, which could worsen the fluctuation issue observed. As a prospective buyer, the 2020 BMW F750’s low mileage and clean MOT history up to 2025 suggest a vehicle that has not been subjected to heavy or frequent use, but this also means several critical checks are essential to assess its long-term roadworthiness. Given its age and the potential for prolonged standing, inspect the tyres for signs of sidewall cracking or perishing, which can weaken the rubber and compromise safety over time. The vehicle’s battery should be tested for health, as low usage can lead to reduced charge cycles, and a 12V battery may struggle under demand from modern electrical systems. Additionally, the brake system should be scrutinised for any signs of corrosion on discs or pads, or for binding calipers, especially in the rear where the advisory was noted. Fluid levels, including brake fluid, coolant, and oil, should be checked for freshness, as fluids degrade over time regardless of mileage, and standing vehicles can accelerate this process. Finally, verify that the service book contains all required time-based maintenance records, such as timing belt replacement (if applicable) and suspension component servicing, to ensure no critical intervals have been missed. The suspension system, given the vehicle’s age and low mileage, may also warrant closer attention. Look for signs of wear on suspension bushes, coil springs, or control arm bushings, which can degrade silently over time. Test the vehicle’s handling by performing a few gentle turns and noting any clunks, rattles, or uneven ride heights, as these could indicate failing components. If the vehicle has been stored in a damp environment, check for rust on the undercarriage, particularly around the wheel arches, exhaust system, and underbody components, as corrosion can compromise structural integrity. The exhaust emissions system should be inspected for leaks or discolouration, as prolonged idling or lack of use can lead to carbon buildup or component failure. While the MOT history is clean, the advisory on the rear brakes remains a critical point of concern, and a thorough inspection of the braking system—including pedal feel, brake fluid condition, and disc/pad condition—should be prioritised. If any issues are found, address them promptly to prevent escalation, particularly given the vehicle’s age and the potential for hidden wear from low usage.
