2012 Mercedes-Benz E 2.1L Diesel · LL62 KHD

The vehicle presents a concerning roadworthiness profile with a clear trend of worsening structural and mechanical integrity. While it passed its most recent test in October 2025 at 273,077 miles, this followed just three weeks prior to a critical structural failure. The tester previously flagged the offside rear upper sub-frame as corroded and seriously weakened, which is a major safety risk. Although this specific failure was rectified, the recurring nature of suspension wear and braking issues suggests that the vehicle is being maintained on a reactive rather than preventative basis. The mileage pattern is exceptionally heavy, averaging nearly 20,000 miles per year over its 14-year life. A significant spike in usage is evident between October 2024 at 164,832 miles and October 2025, where the car covered over 108,000 miles in just twelve months. This high-intensity operation places extreme stress on the drivetrain and chassis, explaining the rapid deterioration of components like suspension arm bushes and wheel bearings. The frequency of travel suggests long-distance use which accelerates the wear of consumable parts. A buyer must conduct a thorough physical inspection of the undercarriage to verify the quality of the repairs made to the corroded sub-frame. The history shows a persistent issue with worn front suspension arm bushes that have been flagged from 2023 through 2025, indicating the front suspension is nearing the end of its life. Additionally, the braking system shows a history of corroded brake pipes and thinning pads. Particular attention should be paid to the efficiency of the parking brake and the state of the front wheel bearings, as these were recurring points of failure in recent tests.
