2012 Mercedes-Benz E 2.1L Diesel · H1 SCJ

The vehicle presents a worsening maintenance trend regarding its braking system and chassis components. While the most recent test on 5 September 2025 at 138,641 miles resulted in a pass, it followed a failure just one week prior on 28 August 2025. That failure highlighted significant service brake inefficiency, worn rear brake discs, and thin rear pads. The persistence of corroded brake pipes, which have appeared in various forms since at least 2021, suggests that while individual components are being addressed, the underlying issue of hydraulic line degradation is not being fully resolved. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 9,900 miles per year. The records show steady usage, moving from 21,469 miles in 2016 to 138,641 miles in 2025. There are no significant gaps in testing history, though the frequency of failures has increased as the vehicle has aged. The jump from 82,480 miles in 2020 to 97,027 miles in 2021, and subsequently to 138,641 miles by late 2025, confirms a regular driving pattern rather than long periods of inactivity. A prospective buyer must prioritise a thorough inspection of the braking system and the underside of the vehicle. The MOT history shows a chronic pattern of corrosion on front, rear, and central brake pipes dating back several years. The tester flagged heavily corroded pipes in August 2022, and although these were cleared, new corrosion issues appeared in the 2025 tests. This indicates a high risk of future hydraulic failure. The recent advisory regarding worn suspension arm pins or bushes at 138,641 miles also suggests that the suspension components are beginning to reach the end of their service life. Further attention should be paid to the rear braking assembly and wheel components. The record shows a history of pitted discs, thin pads, and even instances of brake backing plates catching on discs in 2022. Given the recent failure for brake efficiency and the recurring issues with rear components, the physical condition of the calipers and the extent of corrosion on the mounting points should be verified. The vehicle has also shown a history of minor structural issues, such as distorted wheels and damaged reflectors, which necessitates a close look at the overall condition of the chassis and wheel hubs.
