2014 Mercedes-Benz CLS 2.1L Diesel · V7 NRD

This Mercedes-Benz CLS presents an exceptionally clean and stable roadworthiness profile, culminating in a clean pass on 22 September 2025. The curious same-day failure and subsequent pass on 22 September 2025 with zero recorded defects suggests either a minor, instantly rectifiable issue or a clerical error by the testing station. Aside from this single-day anomaly, the vehicle secured consecutive passes with absolutely no advisory items logged in July 2024, June 2023, and February 2022. This flawless run indicates a highly proactive maintenance regime where the previous owner addressed wear-and-tear items before presenting the vehicle for its annual test. Accumulating 157,116 miles over twelve years represents a high-use profile, averaging roughly 13,000 miles annually. The testing intervals show consistent road use, with the vehicle covering significant distances between the February 2022 test and the most recent inspection in September 2025. High-mileage executive cruisers of this era often cover these distances on motorways, which typically subjects the drivetrain to less stress than stop-start urban driving. However, the sheer mileage means major mechanical components are reaching the end of their natural service life, regardless of how clean the MOT history appears. Prospective buyers must not let the spotless MOT record lull them into complacency. At over 150,000 miles, heavy German executive cars place immense strain on their chassis dynamics. A physical inspection should focus heavily on the front and rear suspension bushes, coil springs, and dampers, which are prone to fatigue. The complex multi-link suspension setup on this chassis can mask wear during basic road tests but will manifest as uneven tyre wear or subtle knocking over road imperfections. The braking system also requires close scrutiny. Check the inner faces of the brake discs for corrosion and ensure the calipers are not binding, as heavy vehicles can warp discs under high-speed braking. Given the age and mileage, inspect the engine bay and underbody for oil migration from the turbocharger, oil cooler, or steering rack. The lack of advisory notes suggests the previous owner invested heavily in preventative upkeep, but a pre-purchase inspection remains vital to verify that expensive components like the exhaust particulate filter and automatic gearbox operate smoothly.
