2009 Mercedes-Benz E 3.0L Diesel · KY09 VNG

A recurring theme of suspension wear and intermittent engine‑management faults runs through the MOT record, with the most recent test on 23 July 2025 returning a pass but still flagging a near‑side rear reflector defect, front‑lower arm ball‑joint play and a corroded rear brake pipe. Earlier that same day a failure was recorded for a non‑functioning near‑side headlamp, a dead engine MIL indicator and both rear position lamps, showing that major electrical and warning‑system issues have required remedial work before the vehicle could be cleared. The pattern of repeated advisories on ball‑joint condition, track‑rod end play and brake‑pipe corrosion, together with several years of engine MIL failures, suggests that the underlying wear has been only partially addressed. At 208,174 mi the car averages roughly 12,200 mi per annum, a mileage level that is above the typical UK average for a 2009 model. The relatively steady annual accumulation, without any long gaps in testing, points to regular use rather than prolonged storage, meaning consumable wear items such as suspension bushings, brake components and tyre tread are likely to be approaching the end of their service life. High mileage also accelerates the progression of under‑body corrosion and can exacerbate any existing oil‑leak condition noted in 2024, so a buyer should expect the need for a thorough inspection of wear‑prone parts. When test‑driving, pay particular attention to the front suspension. Listen for clunks or knocks when passing over bumps, and feel for any looseness or wandering under steering that could indicate the near‑side lower arm ball‑joint approaching detachment or the track‑rod end excess play recorded in 2024. Check that the steering wheel is firm with no excessive wobble, which would corroborate the slight top‑bearing wear noted in 2022. Inspect the rear brake pipe for signs of rust, grease or leakage, and verify that the brake pedal feels solid and does not sink under moderate pressure, as corrosion in the pipe can lead to fluid loss and reduced braking efficiency. The persistent engine MIL indicator failures across 2022, 2024 and 2025 warrant a diagnostic scan to confirm whether the fault lies in a sensor, wiring harness or deeper engine management circuitry. Confirm that all exterior lamps – especially the near‑side headlamp and rear position lamps – illuminate correctly, as these were the cause of a recent failure. Examine the near‑side rear reflector for damage and assess the condition of the tyres, noting that both front and off‑side inner tyres were flagged as close to the legal limit in previous years; uneven wear may point to the suspension issues already highlighted. Finally, verify that the oil leak noted in 2024 is not progressing and that the under‑body corrosion does not affect structural members, as hidden rust can compromise chassis integrity over time.
