2018 Mercedes-Benz E 1.9L Diesel · WN18 DXK

The most recent MOT test on the 2018 Mercedes-Benz E, conducted on 2024-07-26, resulted in a passing outcome with a single minor defect—an inoperative registration plate lamp under the 4.7.1 (b) (i) category. This indicates that the vehicle has maintained a stable roadworthiness status over the past two years, with no dangerous or critical failures recorded. The prior MOT on 2022-12-15 was also clean, and while there was a failure in 2022-12-15 itself—specifically related to front tyre tread depths below the legal minimum of 1.6mm—this was a one-off incident that suggests either a brief period of underinvestment in tyre replacement or a temporary oversight during the vehicle’s operational history. The absence of repeated failures or advisories in subsequent tests reinforces the likelihood that the tyre issue was resolved promptly, leaving no lasting structural or safety concerns. The recorded mileage of 86,555 miles for a vehicle of this age—approximately 10,819 miles annually—falls within the expected range for a car of its class, particularly if it has been driven under typical UK conditions. The steady annual mileage accumulation indicates consistent use rather than prolonged periods of idleness, which could otherwise accelerate wear on consumables like brake pads, suspension components, and internal engine seals. However, the absence of higher mileage spikes or significant gaps in the MOT history suggests that the vehicle has not been subjected to extreme driving conditions or prolonged stationary periods that might exacerbate issues such as corrosion from standing, fluid degradation, or lubricant breakdown. This usage profile is generally favourable, as it aligns with a maintenance schedule that balances wear and tear without extreme stress. For a prospective buyer, the most critical inspection should focus on the front tyres, given the prior MOT failure and the legal requirement for a minimum tread depth of 1.6mm. Visually inspect the front tyres for signs of uneven wear patterns, which could indicate alignment or suspension issues, and verify that the tread depth is now at least 3mm, as the legal minimum is often exceeded in practice to ensure grip. On a test drive, listen for unusual noises from the front suspension, such as clunking or rattling, which may signal worn suspension bushes, coil spring damage, or binding calipers. Additionally, check the brake system for any signs of pulsation or shuddering, which could suggest warped discs or soft pads, and inspect the brake fluid level and condition for signs of contamination or moisture buildup—a common issue in older vehicles that can lead to brake failure. Beyond the tyres and brakes, examine the vehicle’s exterior for evidence of standing corrosion, particularly around the wheel arches, undercarriage, and beneath the front bumper, where moisture can accumulate. The 2018 model year is not excessively old, but the 86,555-mile mark means fluids such as the engine oil, coolant, and differential fluid should be replaced or refreshed in line with manufacturer recommendations—typically every 60,000 to 100,000 miles or every 12 months, whichever comes first. A quick check of the 12-volt battery health is also prudent, as prolonged disuse or high mileage can lead to reduced capacity or failure, which may not be immediately apparent but could cause starting issues or electrical gremlins. Finally, verify that the service book or maintenance records have been updated, particularly for the timing belt (if applicable), exhaust system integrity, and any scheduled inspections for the drivetrain or suspension components, as these are critical for long-term reliability. If the vehicle has been driven regularly, the maintenance history should reflect timely servicing, but if there are gaps, address them promptly to avoid compounding wear.
