2018 Mercedes-Benz E 1.9L Diesel · A5 DWH

The most recent MOT test, conducted on 2025-10-28, resulted in a clean pass with no defects recorded, marking a positive turnaround from the previous failures in 2024. This shift indicates an improvement in the vehicle’s overall roadworthiness, though the earlier failures—particularly the dangerous tyre defects—highlight critical issues that must be addressed promptly. The pattern of failures and advisories over the past two years suggests a history of wear-related problems, notably with tyre integrity and alignment, which could stem from either aggressive driving, underinflation, or structural stress. The absence of further failures since 2024-10-29 implies that corrective actions, such as tyre replacement or suspension adjustments, have been undertaken, but the buyer should remain vigilant for recurring issues, especially in the tyres and headlamp alignment. The recorded mileage of 26,787 miles for a vehicle aged eight years represents a remarkably low annual usage rate of approximately 3,348 miles per annum, which is unusually low for its age. Such low mileage often correlates with prolonged periods of stationary use, particularly in urban environments where vehicles are frequently parked rather than driven daily. This can lead to specific wear patterns, such as accelerated corrosion from condensation in sealed components, potential battery degradation from prolonged disuse, and potential fluid degradation due to stagnation. Additionally, standing for extended periods can cause brake discs to corrode or bind, especially if moisture is present, and may contribute to uneven tyre wear if the vehicle is not moved regularly. The buyer should consider whether the vehicle’s low mileage reflects genuine light use or if it has been left unused for significant periods, which could exacerbate hidden mechanical issues. Given the vehicle’s age and the recorded MOT history, the most critical areas for inspection are the tyres, brakes, and suspension. The 2024 failures—particularly the dangerous tyre defects—demonstrate that the original tyres were compromised, and the buyer should prioritise replacing them with new or high-quality used tyres that meet current legal standards. When examining the tyres, check for sidewall cracks or perishing, which can weaken the structure further, and ensure the tread depth is uniform and above the legal minimum. On a test drive, listen for unusual tyre noise or vibrations, which may indicate misalignment or uneven wear. The previous advisory of nearside front tyre wear close to the legal limit suggests that further monitoring is necessary, and any additional wear should prompt immediate replacement. For the brakes, inspect the discs and linings for signs of corrosion, warping, or binding, particularly if the vehicle has been stationary for extended periods. Binding calipers or seized brake components can lead to dangerous braking performance. Check for any brake fluid leaks under the vehicle and ensure the fluid level is within the specified range; old brake fluid can degrade over time, reducing braking efficiency. The suspension should be checked for excessive play, unusual clunks during cornering, or uneven spring compression, which could indicate worn suspension bushes or damaged coil springs. Additionally, verify that the headlamps are functioning correctly and that their aim is properly adjusted, as the 2024 MOT advisories on headlamp alignment indicate potential issues that may affect visibility and road safety. Finally, given the low mileage, assess the 12V battery health, as prolonged disuse can lead to a weakened or dead battery, and ensure all fluids—particularly oil, coolant, and differential fluid—are topped up or replaced if they appear degraded. If the vehicle has a service history, verify that all scheduled maintenance, such as oil changes and timing belt replacements, has been recorded.
