2010 Mercedes-Benz C220 Bluefficiency SE CDI 2.1L Diesel · LN60 UJO

The 2010 C220 BlueEfficiency presents a stable and reassuring roadworthiness profile. The most recent test on 9 September 2025 at 136,848 miles passed with zero defects, and the preceding failure on 29 August 2025 at 136,789 miles also carried no recorded defects, suggesting a retest following a minor or administrative issue rather than a mechanical fault. The maintenance trend is firmly stable, with no recurring advisories or failures across the available record. For a 16-year-old diesel saloon, this is an exceptionally clean MOT history. The mileage pattern is consistent and unremarkable. The vehicle covered 3,259 miles between the February 2023 test at 124,473 miles and the July 2024 test at 133,590 miles, then just 3,258 miles in the 13 months between July 2024 and September 2025. This indicates very light recent use, averaging roughly 250 miles per month over the last year. The annualised figure of approximately 8,553 miles sits squarely within typical usage for the vehicle's age, and there are no suspicious mileage gaps or sudden spikes that would raise concern about the odometer reading or prolonged periods of inactivity. Despite the clean MOT record, a buyer should still carry out a thorough physical inspection focused on areas the MOT does not fully stress-test. The 2.1-litre OM651 diesel engine is known for EGR valve sooting and swirl flap wear at this mileage, so cold-start behaviour and idle smoothness deserve attention. Check the dual-mass flywheel by listening for rattling at low revs with the clutch engaged, a common failure point on W204-platform cars that MOT tests rarely expose. Inspect the subframes and suspension mounting points for corrosion, particularly around the rear trailing arm bushes, which can deteriorate without triggering a test failure until advanced. Examine the exhaust system for diesel particulate filter integrity and any signs of forced regeneration cycles indicated by soot staining around the manifold. On a short test drive, pay close attention to the 7G-Tronic automatic transmission for hesitation on kickdown and smoothness at low speeds, as mechatronic sleeve wear is a known issue beyond 130,000 miles. Brake binding or uneven pad wear would not have appeared on the record but should still be verified by checking for dragging wheels after a sustained drive. The overall picture is one of a well-kept vehicle with no documented defects, yet the age and mileage demand scrutiny of the drivetrain and corrosion-prone structural areas that a clean MOT alone cannot guarantee.
