2017 Mercedes-Benz C 1.6L Diesel · MW17 AAV

The most recent DVSA examination on 22 December 2025 resulted in a PASS with no defects or advisories recorded, indicating the vehicle is currently meeting statutory roadworthiness requirements. The maintenance trend across the recorded MOT history is largely positive, with passes at each annual test in 2022, 2023, and 2025, all carried out without remarks. However, the 2024 test warrants close attention. On 24 December 2024, the vehicle initially passed but was subject to two advisories concerning nearside and offside front tyres being worn close to the legal limit and on the edge, suggesting uneven wear patterns consistent with suspension or geometry concerns. On the same date, a separate failure was recorded with a major defect for a fractured offside front coil spring, alongside a dangerous failure for an offside rear tyre with tread depth below the 1.6mm minimum, described as a racing slick, which is a serious safety non-compliance. The fact that the vehicle subsequently passed in late 2025 suggests remedial work was undertaken, and a prospective buyer should obtain documentary evidence confirming replacement of the coil spring, the tyres, and any associated wheel alignment work. With 91,764 miles recorded over approximately nine years, the vehicle has averaged around 10,200 miles per year, which is broadly typical for a car of this age and segment. There are no substantial gaps in the MOT timeline that would indicate prolonged standing, and the steady accumulation of mileage suggests regular use, which is generally beneficial for keeping mechanical components, seals, and drivetrain parts in working condition. That said, the cumulative wear associated with approaching 100,000 miles on a Mercedes-Benz C-Class of this generation means that attention should be directed towards service history verification, particularly for items such as the timing chain or belt service interval, automatic transmission fluid and filter changes, and the condition of the diesel particulate filter or petrol direct injection system depending on the variant. The mileage is not excessive but is sufficient to require scrutiny of higher-wear consumables. Given the fractured coil spring recorded in 2024, the suspension system should be inspected thoroughly, as a broken spring often points to general wear of associated components. On a test drive, listen for any clonking or knocking from the front end over uneven surfaces, which may indicate worn suspension bushes, drop links, or anti-roll bar components. Check for uneven tyre wear across both the front and rear axles, as this can suggest lingering geometry issues or weakened springs, and verify that the replacement tyres are of matching brand, size, and load rating. The brake system, given the mileage, should be examined for disc lipping, pad wear, and any signs of binding calipers, particularly if the vehicle has been used for predominantly short journeys. Inspect the underside of the vehicle, wheel arches, and suspension arms for surface corrosion, and examine the exhaust system for signs of deterioration or blowing at joints. For a 2017 vehicle approaching its tenth year, certain age-related checks are essential regardless of the favourable MOT record. Tyre sidewalls should be inspected closely for perishing, cracking, or UV damage, as rubber degrades with calendar age even if tread depth remains adequate. The 12-volt battery should be tested for cranking performance and state of charge, as Mercedes-Benz electrical systems are sensitive to voltage drops, and a failing battery can cause numerous warning messages and module communication faults. Brake fluid should be replaced at the recommended two-year interval to prevent moisture absorption and internal corrosion of the ABS modulator, and the coolant should be checked for condition and concentration. Verify the service book stamps or digital records, paying particular attention to the renewal of the brake fluid, transmission oil, and any items replaced following the 2024 advisories, and consider a pre-purchase inspection by a Mercedes-Benz specialist to assess the underside and confirm the integrity of recent repairs.
