2016 Mercedes-Benz E 2.1L Diesel · HX16 OPB

The Mercedes-Benz E in question presents a clean MOT history over the past two years, with the most recent test in October 2025 at 248,158 miles resulting in a pass—despite a puzzling back-to-back fail and pass at identical mileages (248,104 and 248,158) in early October 2025. This anomaly suggests either a clerical error or a last-minute rectification of an unrecorded minor issue, as no defects were logged in either test. Prior to that, the vehicle passed three consecutive annual MOTs without advisories or failures between October 2022 and October 2024, indicating a stable maintenance trend. The absence of recurring advisories or defects points to consistent upkeep, though the high mileage accumulation—nearly 25,000 miles annually—demands closer scrutiny of wear-prone components. The mileage progression reveals a relentless pace, with 44,340 miles covered between October 2024 and October 2025 alone, and a further 15,118 miles logged in the final month before the most recent test. This rate of use is aggressive for a vehicle of this age, particularly given the Mercedes-Benz E’s reputation for higher-than-average maintenance costs. The lack of gaps between tests also implies the car has been in regular service, though the rapid mileage accumulation raises questions about the intensity of its usage—whether commercial, fleet, or private with frequent long-distance driving. Such mileage would naturally accelerate wear on suspension bushes, brake pads, and drivetrain seals, even if the MOT history remains spotless. For a prospective buyer, the priority should be a thorough inspection of the suspension system, including coil springs, ball joints, and anti-roll bar bushes, given the high mileage. The braking system—particularly the rear calipers and discs—should be checked for binding or uneven wear, as Mercedes-Benz models of this era are prone to heat-related brake issues under heavy use. Exhaust emissions and the condition of the catalytic converter warrant attention, as prolonged high-mileage driving can degrade these components. Structural integrity, especially around wheel arches and underseal, should also be verified, as corrosion or fatigue cracks may not yet be visible but could develop given the vehicle’s age and usage pattern. While the MOT record is reassuring, the mileage demands a pre-purchase inspection by a Mercedes-Benz specialist to confirm no latent issues have arisen.
