2008 Mercedes E 3.0L Diesel · AV08 CFM

A pattern of minor advisories rather than outright failures defines this Mercedes E-Class's mechanical history, with the most recent test on 2026-04-01 returning a clean pass and no defects recorded. The vehicle has now strung together consecutive passes without advisories in 2026 and 2025, suggesting that the cumulative wear items flagged in earlier years were addressed or have not yet deteriorated to recordable levels. The 2024 test introduced a minor oil leak advisory, while 2023 produced the densest cluster of advisories covering anti-roll bar linkages, a front suspension ball joint with slight play, an inner rear tyre worn close to the legal limit, and a deteriorating front registration plate. The 2022 test added only a defective rear exhaust mounting and the same registration plate note. Importantly, no structural corrosion, brake pipe failures, or stop-and-fail items have appeared anywhere in the record, which is a meaningful indicator for a chassis of this age now approaching nineteen years old. The annual accumulation of around 12,900 miles over an eighteen-year lifespan points to consistent, high-mileage use rather than long periods of standing or short-trip-only driving. There are no significant gaps in the testing record, and the regularity of the tests indicates continuous road use throughout the vehicle's life. This sustained level of mileage places proportionate demand on the major mechanical consumables, with the wear signatures typically concentrated in suspension components, engine sealing, and braking hardware. The fact that structural advisories and brake or steering failures are absent despite the mileage suggests the major load-bearing and safety-critical assemblies have held up reasonably well under sustained service. For a prospective buyer, the priority components warranting close physical inspection are the front anti-roll bar linkages and the offside front suspension arm ball joint flagged in 2023. On a test drive, listen for clonking or knocking noises from the front end over speed humps, uneven road surfaces, and during sharp direction changes, as worn anti-roll bar bushes and ball joints commonly present as audible rattles or imprecise turn-in. With the vehicle stationary, attempt to rock each front wheel at the three and nine o'clock positions to detect play in the suspension arms, and pay particular attention to any shimmy through the steering wheel which can indicate worn drop links or tie rod ends. Although no advisories have appeared in the last two cycles, these joints can deteriorate quickly once initial play develops, so a physical check is essential rather than relying on the clean recent passes alone. The 2024 oil leak advisory and the 2022 rear exhaust mounting note also merit direct inspection. With the engine warm, visually examine the underside and the area around the engine sump, valve cover, and turbo or oil filter housing for fresh seepage or staining, and sniff for any burning oil smell once the vehicle is running. Exhaust mounting deterioration on a Mercedes of this age commonly results in the rear section sagging or contacting the underbody, producing a metallic rattle on start-up or over bumps that may disappear once the system warms and expands. The rear inner tyre advisory from 2023 further suggests attention should be paid to current tread depth and any uneven shoulder wear, which on rear-wheel-drive vehicles of this type often points to alignment issues, worn rear suspension bushes, or tracking irregularities. A thorough inspection of these specific areas will provide a reliable read on whether the vehicle remains a sound proposition despite its high accumulated mileage.
