2011 Mercedes-Benz E 2.1L Diesel · WK61 AAA

The vehicle’s roadworthiness record exhibits a concerning deterioration trend, culminating in a critical failure just three months ago. The most recent MOT, passed on 20 April 2026, follows an earlier failure on 4 March 2026 where the rear subframe corrosion rendered the vehicle unsafe for rolling-road brake testing, alongside severe suspension and brake component wear. This suggests a structural integrity compromise that was only rectified after the failure—yet the subsequent pass without defects implies the issue was addressed, though the underlying corrosion risk remains unresolved. The recurring advisories on brake pads, tyres, and suspension bushes indicate a pattern of deferred maintenance, particularly in the rear subframe and hydraulic braking system. The mileage progression of 9,106 miles annually over 15 years aligns with typical usage, though the gap between the January 2025 and April 2026 tests—just 3.5 months—suggests the vehicle was driven actively despite the March failure. The 2024 test at 129,794 miles revealed thin rear brake pads and near-legal-limit tyres, while the 2025 test at 134,319 miles introduced an oil leak advisory, indicating the engine bay was not fully inspected. The absence of tests between January 2023 and January 2024 (a 13-month gap) raises questions about whether critical components were monitored during this period. A prospective buyer should prioritise an immediate inspection of the rear subframe for corrosion progression, particularly around the mounting points, as this was the root cause of the March failure. The front suspension bushes—flagged as excessively worn in 2026—demand verification of binding or play, while the rear brake system warrants scrutiny for pipe corrosion and pad thickness, given the 2024 and 2025 advisories. Tyre wear patterns should be examined for unevenness, especially on the offside, to confirm whether alignment or suspension issues persist. The oil leak noted in 2025 also warrants confirmation of its source and severity, as prolonged neglect could lead to engine damage. Structural components like the under-tray fitment in 2025 may obscure further corrosion, necessitating thorough underbody inspection.
