2010 Mercedes-Benz CLS350 Grand Edit-N CDI A 3.0L Diesel · S14 DWK

The vehicle currently holds a valid MOT certificate issued on 25 July 2024 at 135,113 miles, indicating a stable mechanical condition. While the car failed a test on 5 July 2024 at 134,640 miles, the lack of recorded defects suggests this was likely an administrative issue or a minor oversight rectified immediately before the subsequent pass. The absence of advisories across the last five tests points to a well-maintained vehicle that has avoided the common trend of recurring component failures often seen in high-mileage luxury saloons of this vintage. The recorded mileage of 135,113 miles over sixteen years aligns with typical usage patterns for a diesel Mercedes-Benz. Annual accumulation remains consistent, with a notable increase of approximately 7,000 miles between late 2020 and late 2021, followed by a steady progression toward the current figure. There are no significant gaps in the testing history, which confirms the vehicle has remained in regular operation rather than sitting idle for extended periods, a factor that helps prevent the degradation of rubber seals, fuel systems, and electronic modules. Prospective buyers should focus their physical inspection on the structural integrity of the chassis and the condition of the air suspension system, as these are common failure points for the CLS platform that may not always appear in a standard MOT test. Verify that the vehicle sits level after standing for several hours, as sagging indicates leaking air bellows or compressor fatigue. Check the underside for any signs of corrosion on the subframes and examine the brake lines for surface rust. Ensure the engine operates smoothly through the gear range, as the high-torque diesel drivetrain places significant stress on the transmission mounts and drivetrain components over this mileage.
