2018 Mercedes-Benz CLA 220 Sport D Auto 2.1L Heavy oil · LR18 OAD

The most recent MOT test on April 4, 2026, at 102,424 miles resulted in a failure, though no specific defects were recorded—an unusual omission that warrants immediate scrutiny. The preceding test in January 2024 at 73,085 miles passed without issues, suggesting a stable pattern of compliance with minor wear items (such as wiper blades or bulbs) likely addressed between tests. However, the failure in February 2023 at 59,999 miles—just 1,000 miles before the prior pass—indicates a potential oversight in pre-test maintenance or a systemic issue that was either overlooked or unresolved. The lack of advisories or defects in any test suggests the vehicle may have passed through a "clean slate" MOT process, but the repeated failures without explanation raise questions about whether critical components were overlooked or if the tester failed to identify latent issues. The recorded mileage of 102,424 miles over eight years equates to an average of 12,803 miles annually, which is unusually high for a vehicle of this age and class. This rate implies consistent heavy use, accelerating wear on suspension bushes, coil springs, and drivetrain components. Notably, the gap between the 2022 pass at 47,321 miles and the 2023 failure at 59,999 miles—just 12,678 miles in under a year—suggests either a sudden increase in mileage or deferred maintenance. The subsequent rapid accumulation to 73,085 miles by January 2024 (another 13,086 miles in roughly eight months) reinforces this pattern. While the mileage could reflect genuine high-mileage use, it also raises concerns about whether critical items like brake calipers, suspension mounts, or exhaust systems were inspected or replaced proactively. Given the lack of recorded defects, a buyer should prioritise an independent inspection of suspension components—particularly rear bushes and coil springs—given the high mileage and potential for fatigue. Binding calipers or uneven brake disc wear should be checked, as the repeated failures without explanation may indicate past brake-related issues were either missed or inadequately addressed. Structural integrity, including underbody corrosion and exhaust system integrity, should also be examined, as these are common failure points in high-mileage vehicles. The absence of advisories in any test suggests either diligent maintenance or a history of passing through lenient MOT testers, but neither can be confirmed without deeper inspection. Tyres, despite not being flagged, should be assessed for uneven wear or low tread depth, as high mileage often accelerates tread degradation.
