2004 Mercedes CLK 2.6L Petrol · LG04 LHM

The 2004 Mercedes CLK has a recent MOT history showing mixed results, with the most recent entry on 2026-01-28 recording both a PASS and a FAILED outcome for the same mileage. This inconsistency may indicate a procedural error, but the failed test highlights significant issues, including defective headlamp lenses, a faulty supplementary restraint system warning lamp, and multiple suspension component wear defects. The pass entry also lists similar concerns, suggesting unresolved or recurring problems. Recurring mechanical patterns include suspension arm bushings and pins wearing, brake system anomalies (e.g., parking brake stiffness, service brake binding), and electrical/lighting faults (e.g., repeater lenses, fog lamps, headlamps). These issues align with age-related deterioration, particularly in components like suspension mounts, brake mechanisms, and corrosion-prone areas such as the exhaust and sub-frame. The 2025-01-24 failed MOT specifically noted excessive suspension arm wear, which reappeared in 2026, indicating a persistent risk. The condition trend appears worsening in some areas, as the 2026 failures include more severe defects (e.g., serious headlamp lens damage) compared to earlier reports. However, the vehicle’s low mileage (5,853 miles/year) raises ambiguity. While this suggests lighter use, it could also mean prolonged periods of inactivity, accelerating corrosion and component degradation. The absence of defects in 2024 and 2025 MOTs implies a temporary lull, but the 2026 results signal a resurgence of issues.
