2013 Mercedes-Benz C 2.1L Diesel · KN13 AAJ

The vehicle’s most recent MOT test on 2025-10-21 at 72,028 miles passed without any defects, confirming it remains roadworthy under current UK standards. The test history since 2022 shows a consistent pattern of annual testing with no recurring failures, though the 2024-11-25 retest at 69,829 miles—just two days after a failure—suggests a minor administrative oversight rather than a mechanical issue. No advisories or major component failures (e.g., suspension, brakes, emissions) appear in the record, indicating the tester did not identify any latent problems requiring immediate attention. The lack of defects across five tests implies the vehicle has been maintained at a basic level, though no evidence of proactive servicing (e.g., fluid changes, wear item replacements) is visible in the MOT data. The recorded mileage of 72,028 miles over 13 years—approximately 5,500 miles annually—is unusually low for a vehicle of this age, suggesting either infrequent use or prolonged periods of storage. The gap between the 2022 and 2023 tests (2,190 miles in 11 months) and the subsequent 2023–2024 interval (1,820 miles) shows no rapid acceleration in usage, which might otherwise stress components like brakes or suspension. However, low mileage does not preclude wear from age-related factors such as rubber degradation in suspension bushes or coil springs, or corrosion in underbody panels and wheel arches, which are not tested during an MOT but can compromise structural integrity over time. Given the absence of MOT-recorded faults, a buyer should prioritise an independent inspection of high-wear items not covered by the test, such as the suspension’s rubber mounts and coil springs for cracking or excessive play, and the brake calipers and discs for uneven wear or binding—common issues in older Mercedes models. The lack of advisories does not rule out minor corrosion in wheel arches or sills, particularly if the vehicle has spent time in salty or humid conditions. Additionally, the engine bay should be checked for leaks (oil, coolant) and the exhaust system for rusted joints or broken hangers, as these are not MOT-tested but can lead to emissions failures or structural concerns. The 2024 retest anomaly, while likely procedural, warrants confirming the vehicle’s service history for fluid changes and timing belt maintenance, as these are critical for longevity.
