2003 Mercedes S-Class 3.2L Diesel · PL03 BHF

The 2003 Mercedes S-Class demonstrates a stable maintenance trend with no significant deterioration in its most recent 2026 MOT, which passed despite minor issues including an oil leak, rear brake disc wear, and suspension play. Previous tests from 2025 and 2024 reveal consistent brake disc wear and tyre degradation, with recurring suspension and headlamp defects. While no critical failures were recorded, the accumulation of minor faults suggests ongoing maintenance is required to address wear on braking systems, tyres, and suspension components. The vehicle’s low mileage of 85,447 miles over 23 years (approximately 3,715 miles annually) indicates infrequent use, which may have preserved some systems but also risks component stiffness from prolonged inactivity. Mileage progression shows a steady increase, with 76,396 miles in 2023, 80,247 miles in 2024, 83,799 miles in 2025, and 85,447 miles in 2026. A notable gap exists between the 2023 and 2024 tests, during which mileage rose by 3,851 miles, but no MOT records cover this period. The 2024 test at 80,247 miles recorded a failure due to tyre wear and a nearside front anti-roll bar linkage issue, followed by a pass in the subsequent test. This pattern suggests intermittent oversight in addressing minor defects, particularly with tyres and suspension, which could escalate if neglected. A buyer should prioritise inspecting the braking system for uneven disc wear, which has been flagged repeatedly, and assess the condition of all tyres for cracking or uneven tread. Suspension components, including ball joints and anti-roll bar linkages, require close examination for play or wear. The oil leak, though minor, warrants investigation to prevent potential engine damage. Structural integrity should also be verified, as corrosion risks increase with age, even if not explicitly noted in the MOT records. These checks will confirm whether the vehicle’s maintenance history aligns with its recorded mileage and usage patterns.
