2013 Mercedes-Benz C 2.1L Diesel · LR13 UOA

The vehicle’s most recent MOT test, conducted on 23 December 2025 at 133,996 miles , confirms it remains roadworthy with no defects recorded. However, the immediate preceding test on 16 December 2025 —just seven days earlier at 133,915 miles —resulted in a failure without any specified faults. This abrupt reversal suggests either a technical oversight during the earlier test or a last-minute mechanical adjustment, but it does not indicate a consistent pattern of deterioration. The preceding annual tests in 2024 (both December entries) followed the same alternating pass-fail sequence at similar mileages, reinforcing that this may be an anomaly rather than a trend. No advisories or recurring issues appear in the record, which is unusual given the vehicle’s age and mileage. The mileage progression shows a steady accumulation of approximately 7,627 miles per year over the past three years, consistent with typical usage for a vehicle of this age. There are no prolonged gaps or abrupt spikes in mileage between tests, though the December 2025 tests occurred within a single week, an unusual clustering that warrants scrutiny. The 2023 test at 116,414 miles suggests the vehicle was maintained within a predictable range, with no evidence of prolonged neglect or excessive wear beyond expected consumption for a 13-year-old Mercedes-Benz. However, the lack of detailed defect records—even in failures—means critical components may have been overlooked or repaired privately without official documentation. Given the absence of specific faults in the MOT history, a buyer should prioritise an independent inspection of suspension bushes and coil springs , particularly at the rear, where binding or uneven wear is common in high-mileage Mercedes-Benz models. The brake system —including calipers, discs, and hydraulic lines—should be checked for corrosion or uneven wear, especially if the vehicle has experienced wet or salted conditions. Structural integrity of the floor pans, subframe, and wheel arches must be examined for corrosion, as this is often not flagged in MOT tests until it reaches critical levels. The exhaust system should also be inspected for leaks or excessive rust, as catalytic converter failures are frequently unreported until they cause emissions failures. Finally, the transmission and differential fluids should be assessed for degradation, as these are not routinely checked in MOT tests but can lead to catastrophic failure if neglected.
