2014 Mercedes-Benz SLK 2.1L Diesel · JF08 YAM

The most recent MOT test on January 6, 2026, confirms this 2014 Mercedes-Benz SLK remains roadworthy with no defects recorded at 116,314 miles. The absence of advisories or failures across the last four tests—spanning January 2023 to January 2026—indicates a stable maintenance pattern, though the 2024 January test’s near-simultaneous pass and fail (92,145 and 92,415 miles) suggests either a rushed retest or a minor oversight in scheduling. No recurring faults have been logged, which is unusual for a vehicle of this age and mileage, though the lack of defects does not preclude hidden wear in high-stress components like the suspension bushes or coil springs, which often degrade silently. The mileage progression shows consistent annual usage—around 9,700 miles per year—with no prolonged periods of inactivity or sudden spikes. The gap between the 2024 December and January tests (13,383 miles in 11 months) aligns with typical driving habits, and the 2025-2026 interval (10,776 miles in 18 months) reflects either reduced mileage or a deliberate delay in testing. Notably, the 2024 January retest at 92,415 miles—just 266 miles after the previous pass—implies either a minor administrative error or a quick resolution of an unrecorded issue, though no defects were documented in either test. Given the lack of MOT-reported faults, a buyer should prioritise a thorough inspection of the suspension system, particularly the rear coil springs and bushes, which are prone to fatigue in SLK models of this age. The brakes, while not flagged, should be checked for uneven wear or binding calipers, especially if the vehicle exhibits pulling or reduced stopping performance. Corrosion around the wheel arches, sills, and subframe should also be examined, as this model is susceptible to rust progression in wet conditions. Fluid levels—brake, power steering, and coolant—should be verified, as leaks in these systems often go unnoticed until failure. Finally, the exhaust system’s integrity should be inspected for cracks or leaks, as catalytic converter damage is a common failure point in SLKs approaching 120,000 miles.
