2009 Mercedes-Benz C 2.1L Diesel · LL59 WCC

The most recent DVSA examination on 24 February 2026 resulted in a clean pass with no advisories or defects recorded, continuing a clear pattern of compliance seen at the prior tests in February 2025 and November 2023. Notably, the 5 November 2022 entry shows a failure followed immediately by a pass on the same date, which strongly suggests an on-the-day rectification rather than a serious underlying mechanical issue, and there is no recurrence of any flagged item in subsequent tests. The overall maintenance trend is therefore stable, with no worsening defect history and no recurring advisories to suggest chronic wear points at this stage. Recorded mileage stands at 142,156 miles on a 2009 vehicle, equating to an annual average of approximately 8,362 miles, which is broadly typical for a car of this age. There is no evidence in the MOT history of rapid mileage accumulation between tests, which can sometimes indicate long-distance motorway use and accelerated wear on suspension and drivetrain components, nor are there extended gaps that would point to prolonged standing. The relatively moderate and consistent annual usage suggests the vehicle has been in regular service, which is generally favourable for mechanical longevity, although the 17-year calendar age still warrants attention to time-based deterioration regardless of the odometer reading. Given the clean MOT record and the calendar age of the vehicle, physical inspection should focus on age-related deterioration rather than wear-and-tear advisories. Tyre sidewalls should be examined closely for perishing and cracking, as rubber degrades with time even when tread depth remains adequate, and the spare or spacesaver if present should be checked similarly. Brake discs, particularly the rear ones on this model, are prone to surface corrosion from light use or short journeys, and any binding calipers or uneven pad wear should be identified by jacking each corner and rotating the wheels by hand. The exhaust system, including mounting rubbers and the rear silencer, should be inspected for corrosion given the vehicle's age, and a careful listen for blow or rattle on start-up will confirm integrity. Further age-appropriate checks include verifying the 12V battery's resting voltage and that the terminals are clean and secure, as Mercedes-Benz vehicles of this era are sensitive to voltage drop and can exhibit a range of electrical faults when the battery weakens. Service history stamps should be reviewed to confirm that coolant, brake fluid, automatic transmission fluid (if applicable) and power steering fluid have been changed on a calendar basis, as these degrade chemically over time irrespective of mileage. On a test drive, listen for any clonks or knocks from the front suspension over speed humps and uneven surfaces, which could indicate worn control arm or anti-roll bar bushes, and observe for any pulling under braking or vibration through the steering wheel, which may suggest warped front discs. Finally, ensure all warning lamps extinguish promptly after ignition and that the air conditioning, central locking, and electric windows function reliably, as electrical wear is common on vehicles approaching two decades of service.
