2017 Volkswagen Passat 1.6L Diesel · WJ17 WHR

The Volkswagen Passat in question presents a clean MOT history over the past two years, with the most recent test on 20 April 2026 at 45,917 miles showing no defects or advisories. This consistency suggests the vehicle has been well maintained within the MOT testing parameters, though the repeated failures on the same test date in 2024 and 2025 —both at 33,391 and 39,570 miles respectively—are unusual and warrant closer scrutiny. The fact that no defects were recorded in either failed test implies the issues were likely administrative (e.g., missing documentation, test equipment errors) rather than mechanical. That said, the absence of advisories or defects in the last two passes does not preclude latent problems, particularly in components not routinely checked under MOT regulations, such as internal drivetrain wear or minor suspension degradation. The mileage accumulation of 5,102 miles per year is exceptionally low for a nine-year-old vehicle, indicating either very light use or prolonged periods of inactivity. The gap between the 2024 and 2025 tests —both dated 18 April 2024 and 23 April 2025 —suggests the car may have sat unused for extended periods, which can exacerbate issues like tyre perishing, brake fluid degradation, or suspension seal drying. The fact that mileage increased by 6,182 miles in just over a year (from 39,570 to 45,917 ) between the 2025 and 2026 tests could imply a recent change in ownership or usage pattern. Such fluctuations make it difficult to predict wear trends, but the low mileage reduces the likelihood of severe mechanical fatigue in high-stress components. Given the lack of recorded defects, a prospective buyer should prioritise a thorough inspection of brake system functionality , including caliper operation, disc thickness, and pad condition , as binding brakes were not flagged but could still be an issue given the repeated test failures. The suspension geometry —particularly control arm bushes, coil springs, and track rod ends —should be checked for wear, as low-mileage vehicles often mask early signs of degradation until loaded or driven aggressively. Exhaust emissions and fuel system integrity are also critical, as the MOT does not test for leaks or efficiency beyond basic CO levels. Finally, structural corrosion in high-stress areas such as the sills, subframe, and wheel arches should be examined, especially if the vehicle has spent time in damp or salty conditions. The absence of advisories in recent tests does not eliminate the need for a pre-purchase mechanical inspection, particularly given the irregular mileage pattern and the unexplained test failures.
