2018 Mercedes-Benz E 1.9L Diesel · SC18 RWL

The most recent MOT on 20 August 2026 was passed, but it carried advisories on both rear brake discs for wear, pitting and scoring, and on all four tyres for tread depth approaching the legal minimum. Earlier MOTs in 2024 also highlighted tyre tread wear and rear disc condition, while the 2021‑2023 tests recorded no defects. This pattern shows a gradual increase in wear items rather than a sudden deterioration, indicating a generally stable maintenance regime that is now reaching the point where consumables will need replacement. At 98 428 mi the 2018 E‑Class averages roughly 12 300 mi per year, which is above the typical UK average of 7‑9 000 mi for a vehicle of its age. The higher annual mileage suggests more aggressive use, likely translating into accelerated wear of tyre rubber, brake components, suspension bushings and engine oil life. There are no large gaps in the recorded mileage, so the wear is consistent with steady utilisation rather than long periods of storage. Prospective buyers should concentrate on the rear braking system. The advisories indicate that the rear discs are already pitted and scored; while they remain within the minimum thickness, they are approaching the point where replacement will be required to avoid reduced braking efficiency or vibration under heavy braking. Inspect the rear discs for deep scoring, rust spots or uneven wear, and check the condition of the rear pads – excessive pad wear or glazing will exacerbate disc degradation. On a test drive listen for any pulsation or shudder when applying the rear brakes, and feel for reduced pedal feel or a soft, spongy response, which could signal worn pads or a failing caliper. Front discs have not been flagged, but given the overall mileage it is prudent to measure their thickness and verify that the pads are not near the wear limit. Tyre tread depth on all corners is already close to the statutory minimum, and the presence of edge wear suggests possible mis‑alignment or worn suspension components. Verify that the steering wheel is centred and that there is no pull to one side, and feel for any clunk or knock when negotiating bumps, which would indicate deteriorated bushings, worn ball joints or damaged coil springs. Because the car has been driven heavily, have the battery tested for cranking voltage and inspect the electrolyte level if it is a conventional lead‑acid unit; an eight‑year‑old battery may be losing capacity. Finally, confirm that time‑based services such as coolant, brake fluid and gearbox oil have been performed according to the manufacturer’s schedule, as fluids can degrade even when the vehicle is not driven extensively. A full visual inspection for corrosion on chassis mounts, exhaust hangers and under‑body panels will also help to rule out hidden damage from road salt or standing water.
