2017 BMW 420 2.0L Petrol · 7 PJJ

The vehicle’s most recent MOT, conducted just over a year ago on 29 August 2025 at 52,246 miles, reveals a concerning pattern of tyre wear—all four tyres were recorded as worn close to the legal limit, with uneven edge wear. This is the first defect noted in the full history, suggesting a recent deterioration in tyre maintenance, likely due to underinflation, misalignment, or prolonged neglect. The absence of any other faults in the same test implies the rest of the vehicle remains mechanically sound, but the tyre condition warrants immediate attention. Previous MOTs from 2021 to 2024 showed no defects, indicating a stable maintenance record until this point. The mileage progression of roughly 5,800 miles per year over the past five years aligns with light usage, which could explain the delayed onset of tyre wear. However, the gap between the 2024 (44,990 miles) and 2025 tests (52,246 miles) represents a 7,256-mile interval—nearly double the average—raising questions about whether the vehicle was stationary or driven intermittently during this period. Such prolonged inactivity can accelerate tyre degradation and may have contributed to the edge wear observed. There is no evidence of rapid mileage accumulation, which would suggest more aggressive wear on suspension, brakes, or drivetrain components. Given the tyre condition, a buyer should prioritise an inspection of wheel alignment, tyre pressure history, and potential suspension misalignment, as these factors directly influence uneven wear. The absence of brake-related advisories or structural faults in the MOT history is reassuring, but the rear brakes should still be checked for binding or uneven pad wear, particularly if the vehicle has been stationary for extended periods. Additionally, inspect the suspension bushes and coil springs for excessive play or corrosion, as these components degrade gradually and may not always trigger MOT failures until they are critically compromised. The lack of emissions-related advisories in recent tests suggests the engine and exhaust system remain functional, though a visual check for leaks or corrosion around the catalytic converter and exhaust manifold is advisable.
