2015 Mercedes-Benz E 2.1L Diesel · WN65 GDZ

The most recent MOT on 28 May 2026 was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions standards. Over the past seven years the MOT record shows a mixed pattern: a major failure in early 2025 involving a fractured front coil spring and a continuous oil leak, a major electrical failure in 2021, and a series of minor lamp and tyre‑wear advisories. The successful test in 2026 suggests that the serious defects have been remedied, but the history of major component failure means a prospective buyer should verify the quality of those repairs and monitor for any recurrence. At 160,710 mi for a 2015 model the annual average mileage is roughly 14,600 mi, which is considerably above the typical UK average of 8‑10 000 mi per year. This higher utilisation accelerates wear on wear‑items such as tyres, brake discs, pads, suspension bushings and engine oil. It also implies that the engine and transmission have been subjected to a substantial amount of load cycles, so any latent wear in the timing chain, bearings or clutch (if a manual) may be approaching the end of its service life. The mileage does not show any long gaps that would suggest prolonged standing, so age‑related perishing is likely to be secondary to mileage‑driven wear. The repeated tyre‑wear advisories on all four corners, particularly the inner edges, point to possible mis‑alignment, worn suspension components or uneven tyre loading. A thorough visual inspection should confirm that tread depth exceeds the legal 1.6 mm on all tyres and that sidewalls are free from cracking, bulging or dry‑rot, especially given the vehicle’s age. During a test drive the driver should listen for clunking or knocking from the front suspension, which could indicate lingering issues with the repaired coil spring or worn control‑arm bushes. A quick wheel‑turn check for any pull to one side will help reveal camber or toe mis‑adjustment, and a short brake test should expose any shudder, pulsation or uneven pedal feel that would suggest warped discs, glazed pads or sticking calipers. Given the vehicle’s eleven‑year age, a buyer should also inspect items that deteriorate with time regardless of mileage. The 12 V battery should be load‑tested for cranking capacity and checked for corrosion on terminals. Engine oil, coolant and brake fluid should be examined for colour and consistency, as they degrade on a calendar basis; a fluid change may be prudent if service stamps are missing. Verify that the exhaust system is free of cracks, rust or excessive soot, and that the under‑body shows no significant corrosion, especially around the wheel arches and suspension mounting points. Finally, request a full service history to confirm that the oil leak identified in 2025 was correctly rectified and that any timing chain or valve‑train maintenance has been performed in line with Mercedes‑Benz recommendations.
