2007 Mercedes-Benz E 3.0L Diesel · EK07 OLB

The 2007 Mercedes-Benz E presents a pattern of recurring mechanical advisories spanning electrical, braking, and chassis systems rather than isolated incidents. Two consecutive failed MOT tests in early 2024—one on 2024-03-18 and another on 2024-03-19—demonstrate persistent faults including deteriorating rear brake hose connections, corroded anti-roll bar assemblies, and faulty position lighting, before the vehicle finally achieved a passing result on 2026-03-25 which retained several prior advisories such as the rear seat belt webbing and oil leakage concerns. While the most recent test outcome was positive, the continued presence of advices on critical safety systems signals that underlying issues have not been fully resolved, and the overall mechanical picture should be viewed through the lens of accumulated wear rather than pristine condition. Regarding mileage, the recorded 128,242 miles on a 19-year-old vehicle equates to approximately 6,750 miles per annum, which aligns with expected usage patterns for a model of this age and reflects moderate daily turnover over its lifespan. The test coverage reveals notable gaps between the 2023-03-22 and 2024-03-18 assessments—a delay of nearly nine months—followed by a cluster of three consecutive tests in late 2024 and early 2025. This irregularity may indicate variable ownership patterns or extended periods where the vehicle was not driven, yet the cumulative mileage suggests consistent operational use throughout much of its life. The high annual mileage combined with the recorded failures points toward progressive degradation in components subject to constant loading and environmental exposure. Focusing on the specific components flagged in the MOT history provides actionable insights for a prospective buyer. The recurring corrosion on the nearside rear position lamp, rear brake hoses, and front anti-roll bars represents a chassis and braking subsystem that requires close attention during a test drive: listen for hissing or pulsating noises when approaching speed bumps, and verify that the rear lights illuminate correctly at all angles and that the interior position indicator illuminates without flickering. The rear brake pipe connection entering the absorbent block showed a serious leak in 2024-03-24, and while the 2026-03-25 pass did not resolve this, the persistence of oil leakage advisories and the noted deterioration of rear brake hoses suggest the braking system has experienced significant internal wear; expect to observe soft spots or reduced braking response when applying the foot pedal, particularly under hard braking conditions. Additionally, the inner arch suspension mounting area was corroded on both 2024-03-18 and 2024-03-19, meaning the front lower control arm bushings and related linkages may exhibit play or uneven ride height, which could manifest as a clunking noise over bumps or a noticeable jump in the ride quality. For a thorough pre-purchase examination, prioritize a test drive that includes both acceleration and deceleration phases to assess brake performance, and pay particular attention to the rearward-facing components during turns where weight transfer stresses the anti-roll bars and rear suspension bushings. Inspect the rear brake hose routing for signs of further deterioration or bulging, and confirm that the rear seat belt webbing remains intact and free of fraying despite the 2026-03-25 advisory. Given the documented history of electrical glitches affecting position and direction indicators, also verify that all exterior lighting functions properly, as intermittent failures here can compromise night-time visibility. If possible, request that the seller provide documentation of any repairs made since the last failed test, as the persistence of advices despite a passing result often indicates that corrective work has not been completed to specification. These specific checks will help determine whether the vehicle’s remaining life is adequate for your intended use or warrants replacement given the evident progression of component failures.
