2014 Mercedes-Benz CLS 3.0L Diesel · PL02 ANO

The 2014 Mercedes-Benz CLS has maintained a clean MOT history with no defects recorded across the last five tests, including the most recent pass on 8 December 2025 at 82,981 miles. This suggests consistent compliance with UK roadworthiness standards, though the single failure in December 2022—despite being retested immediately—stands out as an anomaly. No recurring faults appear in the record, and the absence of advisories implies either diligent servicing or components that have not yet reached critical wear thresholds. However, the 2022 retest at identical mileage (66,968 miles) without explanation raises a minor concern about potential oversight or a non-MOT-related issue that was addressed privately. The vehicle’s mileage progression of approximately 6,915 miles per year aligns with typical usage for its age, though the gap between the December 2022 failure and the subsequent December 2022 pass—just ten days apart—is unusually short. This suggests either a rapid resolution of an unlisted issue or a scheduling quirk. No extended periods of inactivity are evident, and the steady mileage increments indicate regular use rather than neglect. The most recent test, just over seven months ago, remains within the acceptable window for a vehicle of this age, though buyers should verify whether the current owner has adhered to recommended service intervals beyond MOT requirements. Given the lack of recorded defects, priority should be given to inspecting high-wear components that often fail without MOT-triggering symptoms. The suspension—particularly rear coil springs and bushes—should be checked for uneven sagging or excessive play, as Mercedes-Benz models of this era are prone to bush deterioration. Brake systems warrant scrutiny: while no binding calipers or warped discs were flagged, rear brake wear can escalate silently, and the 2022 retest hints at a past issue that may not have been fully resolved. Structural integrity is another concern; corrosion around wheel arches, sills, and the subframe should be examined, especially given the vehicle’s age and typical exposure to UK road salt. Finally, the exhaust system’s integrity—particularly at rear mounts—should be verified, as catalytic converter failures or leaks are common in this model range and often go unnoticed until emissions tests or drivability issues arise.
