2012 Mercedes-Benz C 2.1L Diesel · H9 SHN

The vehicle’s most recent MOT test on 14 April 2025 at 128,624 miles passed without any defects, confirming it remains roadworthy under current UK standards. The absence of advisories or failures in the last three tests—including the 2024 and 2022 cycles—suggests a stable maintenance pattern, though the near-consecutive September 2022 tests (a failed then passed) indicate a brief oversight rather than a systemic issue. No recurring faults appear in the record, and the lack of advisories implies no deferred or neglected repairs were carried forward. Mileage progression shows consistent usage, averaging around 9,200 miles annually, which aligns with typical expectations for a vehicle of this age. The gap between the 2021 and 2022 tests (a 17,316-mile span) is slightly longer than the 12-month intervals of later tests, but this does not necessarily indicate neglect—it may reflect seasonal or owner-specific driving habits. The 2022 failure followed immediately by a pass at the same mileage suggests either a minor oversight in the first test or a quick resolution of a non-critical issue, such as a loose component or minor emissions anomaly. Given the clean MOT history, a buyer should prioritise an in-person inspection of high-wear components typical for this mileage and age. Focus on the suspension system—particularly the rear coil springs and bushes—for signs of deterioration, as Mercedes-Benz vehicles of this era are prone to bush wear over 120,000 miles. The braking system should be scrutinised for uneven disc thickness or binding calipers, especially if the vehicle has been driven in mixed conditions. Structural integrity checks for corrosion around wheel arches, sills, and the subframe are also warranted, given the vehicle’s age. Finally, verify the condition of the exhaust system for leaks or excessive rust, as this is a common failure point in older Mercedes-Benz models. The absence of MOT advisories does not preclude these areas from requiring attention.
