2009 Mercedes CLK220 CDI Sport Auto 2.1L Heavy oil · IFZ 2915

This Mercedes CLK220 CDI from 2009 has maintained a clean MOT history through five consecutive tests, all passing without defects or advisories. The most recent inspection on 31 March 2026—just four months ago—confirmed the vehicle’s compliance with current UK roadworthiness standards, with no indications of failing components or unresolved issues. The absence of recurring faults across these tests suggests that, at least in terms of MOT criteria, the vehicle has been consistently maintained to meet minimum legal requirements. However, the lack of advisories or defects does not preclude underlying wear or deferred maintenance beyond MOT scope, particularly in areas not routinely tested, such as suspension geometry, drivetrain seals, or internal engine wear. The recorded mileage of 87,197 miles over 17 years—approximately 5,129 miles annually—is unusually low for a vehicle of this age, particularly given the model’s typical usage patterns. The mileage increments between tests are consistent, averaging around 3,860 miles per year, with no abrupt jumps or prolonged periods of inactivity. For instance, the gap between the 2022 and 2023 tests saw just 2,238 miles logged, suggesting the vehicle may have spent extended periods stationary. While low mileage generally correlates with reduced wear on high-stress components like brakes, tyres, and suspension, it can also indicate neglect in other areas—such as fluid changes, minor servicing, or exposure to environmental damage—if the vehicle was stored without proper care. Given the clean MOT record, a buyer should prioritise an independent inspection of components not routinely checked during the test. Focus on the suspension, as coil springs and bushes in this model are prone to fatigue over 17 years, even with low mileage. Binding or uneven brake calipers—especially rear—should be tested for, as past MOTs would only flag severe failure, not gradual wear. Examine the underbody for corrosion, particularly around the sills, subframe, and exhaust system, as prolonged storage can accelerate rust. The engine bay should be inspected for leaks from the turbocharger, oil cooler, or intercooler, as these are common failure points in CDI engines of this era. Finally, verify the integrity of the exhaust system for cracks or excessive play in mounts, as emissions-related faults are not always captured until they reach a critical stage.
