2010 Mercedes-Benz E 3.0L Diesel · OV10 FTZ

The most recent MOT test on 2026-01-07 resulted in a clean pass, marking a return to compliance after a failure in late 2025 that highlighted critical issues requiring immediate attention. While the vehicle’s MOT history shows a pattern of stability—with only one failure in the last six years—this incident in 2025 was particularly concerning, particularly the "Dangerous Dangerous" failure of the front brake pipe at imminent risk of fracture, which is a severe safety defect that would have rendered the vehicle unsafe for road use until rectified. The major failure of the near-side front coil spring fracture further underscores the need for thorough mechanical scrutiny, as coil springs are critical for structural integrity and ride control; their failure can lead to uneven suspension travel, binding, or even catastrophic collapse if not addressed promptly. The emissions failure due to engine misfire, while not directly linked to roadworthiness, indicates ongoing issues with the vehicle’s fuel management system, which may persist if not serviced. The vehicle’s recorded mileage of 96,279 miles at 16 years old represents an average annual usage of approximately 6,017 miles, which is consistent with its age and typical usage patterns for a high-mileage European luxury car. However, the gap between the 2020 MOT and the 2025 failure suggests periods of prolonged inactivity, potentially leading to secondary issues such as corrosion from standing, degraded fluids, or wear from infrequent use. The brake advisories from 2020 and 2019—particularly the corrosion on the inner brake disc faces—may indicate prolonged idling or lack of regular braking activity, which can accelerate corrosion and reduce disc lifespan. Additionally, the brake pipe failure in 2025 implies that the vehicle may have been subjected to heavy braking or improper maintenance, warranting a closer inspection of the entire braking system for signs of further wear or corrosion. Given the recent MOT failure and recurring advisories, the prospective buyer should conduct a meticulous mechanical inspection focusing on the front suspension and braking systems. During a test drive, listen for unusual noises such as clunks or rattles from the front suspension, which could indicate loose or failing components, and check for uneven tyre wear or pulsations that may suggest binding calipers or warped brake discs. Inspect the front brake pipes for leaks, corrosion, or signs of recent repairs, as the 2025 failure suggests a history of potential damage. The coil springs should be visually inspected for signs of further deterioration or cracks, and the vehicle’s ride height should be checked for asymmetry, which could indicate spring or bush failure. Additionally, verify that the brake discs are free from excessive pitting, scoring, or corrosion, and that the brake pads are not excessively worn or glazed. The brake fluid level should be checked for contamination or bubbles, as this could indicate a failing master cylinder or brake booster. For the buyer, given the vehicle’s age and the history of infrequent use, a broader physical inspection is warranted to address potential issues from standing and calendar-based degradation. Check the tyre sidewalls for signs of perishing, cracking, or dry rot, which can compromise tyre integrity and safety, especially if the vehicle has been stored for extended periods. Inspect the undercarriage for signs of rust, particularly around wheel arches, exhaust systems, and the subframe, as prolonged idling can accelerate corrosion in these areas. The 12V battery should be tested for voltage and charge capacity, as older vehicles may struggle with electrical systems if the battery has degraded from lack of use. Fluid levels—particularly brake fluid, coolant, and transmission fluid—should be checked and topped up if necessary, with a note on the last service date, as fluids degrade over time even with minimal usage. Finally, the exhaust system should be inspected for leaks, discolouration, or signs of catalytic converter failure, as emissions issues from 2025 may persist if the engine management system remains problematic. A thorough check of the service history, including oil changes and fluid replacements, would also provide insight into the vehicle’s maintenance record and help identify any missed servicing.
