2009 Mercedes-Benz E 3.0L Diesel · LS59 OPN

The most recent MOT, carried out on 21 October 2025, was passed with no recorded defects, indicating that the vehicle met the statutory safety and emissions standards at that time. However, the MOT record shows a pattern of recurring advisory items – notably front brake pipe corrosion each year since 2022 and a serious sub‑frame corrosion failure in September 2022 – suggesting that while the vehicle has been kept road‑worthy, underlying rust issues have not been fully resolved. The trend is therefore one of marginal improvement in that the vehicle now passes without a failure, but the persistence of corrosion advisories points to a maintenance situation that remains borderline and warrants close scrutiny. At 107,285 mi recorded in September 2026, the car averages roughly 6,300 mi per annum over its 17‑year life, which is considerably below the typical UK usage rate of 10‑12 000 mi per year. Such low annual mileage can be a positive sign of reduced mechanical wear, but it may also indicate prolonged periods of inactivity. Extended standing can accelerate tyre sidewall perishing, battery sulphation, and the progression of rust on chassis and suspension components, especially in a vehicle that already shows sub‑frame corrosion. Prospective buyers should give particular attention to the brake pipe and sub‑frame condition. Inspect all brake hoses for surface rust, pitting, or signs of grease covering, and verify that there is no fluid leakage at the pipe connections or around the calipers. During a test drive, feel for any softening or sponginess in the brake pedal, and listen for metallic clunks that could indicate weakened mounting points. The major sub‑frame corrosion noted in 2022 should be examined visually for rust at the lower arm anchor and surrounding welds; any flaking or pitting may compromise structural integrity and could require welding or replacement. Additionally, the tyre advisories from 2022 suggest that the rear tyres were close to the legal tread limit; check the current tread depth, sidewall condition, and the DOT manufacture date to ensure the tyres are not aged beyond safe service life, even if the remaining tread appears adequate. Beyond the specific corrosion concerns, a comprehensive age‑related inspection is advisable. Verify the condition of the 12 V battery, looking for swollen cases or excessive resistance that can develop after years of storage. Examine the suspension bushings, ball joints and coil springs for cracked rubber, corrosion or excessive play, as these components can deteriorate even with low mileage. Confirm that the engine oil, coolant and brake fluid have been changed in accordance with time‑based service intervals, as fluid degradation can occur regardless of mileage. Finally, review the service book for evidence of regular oil changes, filter replacements and any remedial work on the chassis, as a well‑documented maintenance history will help mitigate the risks associated with the vehicle’s age and its documented corrosion issues.
