2012 Mercedes-Benz E 2.1L Diesel · AD09 JEM

The vehicle remains roadworthy but the maintenance trend shows a clear worsening trend regarding the braking system integrity. While it passed the most recent test in March 2026 at 107,552 miles, the tester identified four separate instances of corroded brake pipes across the front and rear sections. This represents a regression from March 2025, where only the two front pipes were flagged. The presence of a fluctuating offside rear service brake further indicates potential caliper wear or piston issues that require monitoring to prevent seizing. At 107,552 miles over 14 years, the car averages approximately 7,682 miles per year, which is consistent with typical low-use use for this age. The data shows steady usage patterns, with roughly 7,700 miles driven between the 2025 and 2026 tests, and another 6,800 miles between the 2024 and 2025 tests. This consistent mileage suggests the vehicle is not sitting for long periods, which explains the mechanical wear observed rather than age-related neglect. A buyer must prioritize a thorough physical inspection of the brake lines. The recurring corrosion on the front arch area and the front-to-rear pipes suggests that the protective coatings are failing or the environment has accelerated metal degradation. Additionally, the history shows a March 2024 failure for rough front wheel bearings and the 2023 report of uneven tyre wear and sidewall cracking indicates potential suspension geometry issues or worn bushings. The buyer should check for signs of misalignment in the tyres, as the record shows a recurring history of failing on tread depth and legal limits.
