2014 Mercedes-Benz E 2.1L Diesel · AD52 AAD

The most recent MOT test on 2026-07-08 resulted in a clean pass, indicating no roadworthiness failures and no outstanding defects beyond the advisories noted in prior tests. This follows a consistent pattern of passing MOTs since 2023, with the only recurring issues being suspension-related advisories—specifically corrosion in the rear coil springs and wear in the front suspension arm bushes—both of which were deemed not to compromise safety but required monitoring. The presence of undertrays throughout the vehicle’s history suggests either a proactive approach to corrosion protection or a standard practice for the model, though the advisories on coil spring corrosion and suspension bush wear indicate that the vehicle has experienced some exposure to environmental factors that accelerate wear, particularly in the suspension system. This trend, while not deteriorating, warrants ongoing attention to prevent potential long-term structural or functional degradation. The recorded mileage of 78,486 miles for a vehicle aged approximately 12 years represents a moderate annual usage rate of around 6,540 miles per year, which is within the expected range for a car of this age and class. While lower mileage could imply periods of inactivity or lighter use, which might have slowed wear on consumables and drivetrain components, the consistent mileage accumulation suggests regular, albeit moderate, operational exposure. Higher mileage would typically accelerate wear on critical components like brakes, suspension bushes, and tyres, but the given figures do not suggest an unusually aggressive usage pattern. However, the advisories on suspension components suggest that even at this mileage, the vehicle has encountered conditions that have contributed to premature wear, particularly in the rear coil springs and front suspension bushes, which may have been exacerbated by prolonged exposure to moisture or road debris. Given the recurring advisories on coil spring corrosion and suspension bush wear, the prospective buyer should prioritise a thorough inspection of the suspension system during the purchase process. Focus on the rear coil springs, checking for signs of further corrosion or mechanical failure, such as excessive sagging, unusual noises during cornering or over bumps, or any audible clunking when the vehicle is driven over rough surfaces. The front suspension arm bushes should be examined for play or excessive movement, which could manifest as a lack of responsiveness in steering or a clunking sound when the vehicle is driven at speed. Listen for any unusual suspension noises, particularly during the test drive, and check for uneven tyre wear patterns, which may indicate misalignment or suspension imbalance caused by worn components. Additionally, inspect the undertrays for any signs of damage or wear that could compromise the vehicle’s structural integrity or expose critical components to further corrosion. For this vehicle’s age and mileage, the buyer should also conduct a comprehensive physical inspection of several key areas to ensure roadworthiness and longevity. Begin with the tyres, checking for sidewall perishing or cracking, which can weaken the rubber and reduce grip, especially if the vehicle has been stationary for extended periods. Verify the tread depth is within legal limits and that there is no evidence of uneven wear, which could indicate suspension or alignment issues. Inspect the brake system for signs of corrosion on discs or binding calipers, particularly if the vehicle has been parked for prolonged periods, as standing fluid can cause corrosion and reduce braking effectiveness. Test the brake pedal for firmness and ensure there is no sponginess or excessive travel, which could signal fluid degradation or air in the system. Finally, check the battery and associated electrical connections for signs of corrosion or poor contact, as older vehicles are more susceptible to battery failure due to the natural degradation of lead-acid batteries over time. Additionally, verify that the service history, particularly for fluid changes, is up to date, as time-based servicing—such as brake fluid, coolant, and transmission fluid—is critical for maintaining performance and preventing catastrophic failure. If the vehicle has been used sparingly, consider scheduling a fluid flush and a comprehensive suspension inspection within the next 12 months to address the advisories and ensure continued reliability.
