2015 Mercedes-Benz CLS 3.0L Diesel · AF08 WEN

The most recent DVSA examination on 13 November 2025 recorded a PASS with no advisories or defects noted, continuing a stable and well-maintained test history for this Mercedes-Benz CLS. Across the documented seven-year MOT record, the vehicle has passed on every occasion with only one minor failure recorded in November 2023, which related solely to the front and rear registration plates not conforming to specified requirements and was remedied immediately prior to the following day's pass. Aside from that administrative item, the only advisories on file are a nail in the nearside front tyre in 2022 and excessively clean emissions output in 2020, neither of which points to any underlying mechanical concern. Overall, the maintenance trend is stable and suggests a vehicle that has been conscientiously prepared for test, with no recurring wear items or component deterioration flags in the official record. With 80,909 miles recorded over approximately eleven years, this CLS averages around 7,355 miles annually, which sits squarely within typical usage parameters for a premium executive saloon of its age. There are no significant gaps or sudden mileage surges evident between test entries, indicating either consistent regular use or sensible accumulation without excessive long-distance driving. This average annual mileage means the drivetrain, suspension, and braking systems will have experienced moderate working life but are unlikely to have been subjected to extreme wear. Equally, the mileage is not so low as to raise immediate concerns about prolonged standing periods, though any owner should still remain alert to deterioration that can occur from irregular use. Given the relatively clean MOT history and absence of recurring defects, physical inspection should focus on age and calendar-related deterioration rather than chasing specific recorded problems. Tyres should be closely examined for sidewall perishing and cracking, which is common on vehicles of this vintage regardless of tread depth, and the spare or inflation kit should be checked for serviceability. Brake calipers, particularly on a Mercedes of this era, are known to seize or bind after periods of light use, so a test drive should include firm pedal application from speed to confirm the vehicle pulls evenly and that no juddering or grabbing is evident from the discs. Surface corrosion on the discs, especially after wet standing periods, is normal, but deep pitting or lipping felt through the steering warrants further investigation. The 12V battery, cabin filtration, brake fluid, coolant, and transmission fluid all degrade with time rather than mileage alone, so verification of the service book stamps and recent replacement invoices is essential for a car approaching its twelfth year. A diagnostic readout using Mercedes-specific tooling or a capable aftermarket scanner would be prudent to confirm no stored fault codes relating to the AIRMATIC suspension, common Mercedes systems including the catalytic converter oxygen sensors, or electronic throttle adaptations. On the road, listen for suspension clonks over speed humps and uneven expansion joints, which would indicate worn bushes, top mounts, or coil springs, and verify that the auto gearbox shifts smoothly through all ranges without hesitation or flaring. Finally, check the condition of the undertrays and engine covers referenced in the 2020 advisory, ensuring they remain securely fitted to protect ancillary components and to avoid any future MOT complications.
