2015 BMW 420 2.0L Diesel · N29 THK

The vehicle’s most recent MOT on 2025-12-22 at 124,361 miles showed no defects, indicating a stable roadworthiness status. However, a prior failure on 2024-09-27 at 111,208 miles—just one day before a subsequent pass at 111,525 miles—suggests potential inconsistency in testing or minor unresolved issues. The absence of defects in both the failed and passed tests implies the failure may have been a technicality or administrative error. Overall, the trend shows no significant deterioration, with no recurring mechanical or structural concerns flagged in the last three years. The vehicle’s mileage of 124,361 miles over 11 years aligns with an average of 11,306 miles annually, reflecting typical usage for its age. MOT records show consistent testing intervals, with no prolonged gaps between assessments. The 2023-01-18 test at 105,488 miles and 2022-02-03 test at 92,929 miles confirm steady mileage progression. No rapid accumulation or extended inactivity periods are evident, suggesting regular operation. The record is otherwise clean, with no advisories or critical failures documented beyond the single unexplained failure. A buyer should verify the condition of suspension components, particularly bushes and coil springs, which may degrade over time without MOT coverage. Brake systems, including calipers and discs, should be inspected for wear, as these are not always tested comprehensively. Structural corrosion, though not mentioned in records, warrants scrutiny, especially in older models. The absence of defects in recent tests is reassuring, but physical inspection remains crucial to confirm the vehicle’s mechanical integrity beyond documented MOT data.
