2017 BMW 5 Series 3.0L Diesel · KA05 NJA

The most recent MOT test on the 2017 BMW 5 Series was conducted on 2025-10-07 and resulted in a clean pass, with no defects recorded. This follows a series of MOTs that show a generally stable maintenance profile, though there are notable exceptions. The vehicle’s MOT history includes two failed tests in 2021 and 2022, primarily due to brake pad wear and tyre defects, which suggest that the braking system and tyres have been subject to more scrutiny or wear than other components. The absence of failures in the past two years indicates a return to consistent roadworthiness, but the recurring advisories on brake discs—particularly the nearside and offside front inner discs showing pitted or scored surfaces—highlight a pattern that warrants closer attention. These advisories, while not failing the vehicle outright, indicate ongoing wear that may escalate if not addressed, especially given the vehicle’s age and accumulated mileage. The recorded mileage of 71,814 miles for a 2017 model represents a reasonable annual usage rate of approximately 7,979 miles per year, which is typical for a vehicle of this age and class. This figure does not suggest excessive driving or undue wear, but it also does not indicate light or infrequent use, which could have mitigated certain wear patterns. The absence of significant mileage gaps between MOT tests suggests the vehicle has been in regular service, though the presence of the failed brake pad and tyre issues in 2021 and 2022 may reflect either aggressive braking or tyre management that accelerated component wear. For a vehicle of this age, the mileage alone does not guarantee structural integrity, and potential issues such as suspension wear, fluid degradation, or internal component fatigue should be evaluated alongside the MOT history. Given the recurring advisories on the brake discs, the prospective buyer should conduct a thorough inspection of the braking system during the test drive. Listen for any unusual noises such as grinding, squeaking, or pulsations when applying the brakes, as these could indicate worn pads, warped discs, or binding calipers. Visually inspect the brake discs for uneven wear, scoring, or signs of overheating, and check the brake fluid level and condition—low or contaminated fluid can exacerbate disc pitting. The nearside and offside front discs showing pitted surfaces may require replacement within the next 1,000 to 2,000 miles, depending on driving habits, to prevent further damage to the discs or potential failure. Additionally, verify that the rear brake pads have been replaced since the last MOT failure, as the legal minimum thickness of 1.5 mm is critical for safe stopping performance. Beyond the brake system, the buyer should also address the tyre defects noted in the MOT history, particularly the offside rear tyre tear and nearside rear tyre wear close to the legal limit. A physical inspection of the tyres should confirm the extent of the tear and ensure the remaining tread depth is safe and evenly distributed. The tear could indicate underlying structural weakness or improper tyre fitting, which may require professional assessment. For the remaining tyres, check for sidewall cracks or perishing, which can compromise tyre integrity over time, especially in a vehicle of this age. Given the vehicle’s mileage and age, it is prudent to replace the tyres before they reach the 4mm legal minimum tread depth, as this will improve grip and safety. Lastly, consider a basic inspection of the suspension components, such as the coil springs, shock absorbers, and suspension bushes, for signs of excessive play or wear, as these can degrade with age and mileage. A test drive should include checking for clunking noises from the suspension, uneven ride height, or excessive bounce, which could signal failing components that may need servicing soon.
