2017 BMW 420 2.0L Diesel · AL14 ABU

The latest MOT test for this 2017 BMW 420i, conducted on 2025-11-06, resulted in a clean pass with no recorded defects, marking a positive conclusion to a maintenance history that has otherwise been characterised by consistent advisories rather than failures. Over the past five years, the vehicle has maintained a stable MOT record, with only minor issues noted—primarily related to tyre wear, wheel bearing noise, and suspension component wear—rather than any critical failures that would compromise roadworthiness. The advisories from previous tests, such as thin brake pads and worn tyre edges, suggest routine wear progression typical of regular use, but none have escalated to the point of failure, indicating that while the car has accumulated significant mileage, it remains within safe operational parameters for now. The vehicle’s recorded mileage of 93,026 miles at the time of this assessment represents a moderate annual usage rate of approximately 10,336 miles per year, which is within the expected range for a BMW of this age and class. This level of mileage does not indicate excessive wear beyond what is anticipated for a car that has been driven in typical UK conditions, including variable weather and road surfaces. However, the advisories from the 2021 and 2024 MOTs—particularly the thin brake pads—highlight that brake systems should be monitored closely, as prolonged wear can lead to reduced stopping performance or even failure if not addressed. The presence of a near-side front tyre worn close to the legal limit and a rear tyre also nearing the limit suggests that tyre rotation or replacement may be advisable soon to prevent uneven wear patterns or premature tyre failure. As a prospective buyer, you should conduct a thorough physical inspection of the vehicle beyond the MOT record, focusing on areas where wear and potential issues have been flagged. Begin with the tyres, checking for sidewall cracks or perishing, which can weaken their structural integrity, especially given the vehicle’s age. Inspect the front and rear tyres for consistent tread depth and signs of uneven wear, as the advisories suggest some lateral wear, which could indicate misalignment or suspension issues. Listen for any unusual noises during a test drive, particularly from the wheel bearings, which the 2024 MOT noted as slightly noisy; a clunking or grinding sound from the front wheels could indicate further wear or damage. The suspension components, including the Macpherson strut pin or bush, should be checked for excessive play or signs of leakage, as the 2024 advisory suggests some wear but no immediate failure. For the brakes, visually inspect the discs and pads for signs of glazing, warping, or excessive thickness loss, as the MOT advisories indicate they are wearing thin. Listen for a grinding sound when applying the brakes, which would signal metal-to-metal contact and require immediate attention. The brake fluid should be checked for contamination or moisture, which can degrade performance over time, particularly if the vehicle has been stationary for prolonged periods. Additionally, verify the condition of the 12V battery, as older BMWs can suffer from reduced capacity or corrosion in terminals, especially if the car has been left unused for extended periods. Lastly, examine the undertray for signs of rust or damage, as the 2023 MOT noted its presence, and any corrosion could compromise the vehicle’s structural integrity or emissions system. Given the vehicle’s age and mileage, consider scheduling a service check to confirm that fluid levels—such as coolant, oil, and brake fluid—are up to date, as these can degrade over time even without significant mileage accumulation.
