2018 Mercedes-Benz E 1.9L Diesel · WG18 WWB

The most recent MOT test on the 2018 Mercedes-Benz E recorded a passing result, indicating that the vehicle is currently roadworthy with no critical failures. However, the preceding MOT history reveals a pattern of persistent tyre wear advisories and a significant failure in 2024, where the offside front lower suspension arm ball joint was classified as excessively worn. This failure suggests that the suspension components, particularly the ball joints, have been under stress over time, with the 2024 test highlighting severe wear beyond the advisory threshold. The advisories from previous MOTs—particularly the repeated tyre edge wear and front brake pad thinning—point to ongoing mechanical issues that may have been neglected or only partially addressed, warranting closer scrutiny during a thorough inspection. The vehicle’s recorded mileage of 48,999 miles at the time of this assessment represents a reasonable annual usage rate of around 6,125 miles, which is typical for a car of this age and class. This figure does not suggest excessive wear from high mileage alone, but the combination of the suspension ball joint failure and persistent tyre wear advisories implies that the vehicle has either undergone significant stress, such as heavy or aggressive driving, or has experienced prolonged periods of standing in a way that accelerates component degradation. The lack of substantial mileage gaps does not necessarily mitigate the risk of hidden wear, especially in suspension and braking systems, which are critical for roadworthiness and safety. For a prospective buyer, the most urgent concerns stem from the confirmed failure of the offside front lower suspension arm ball joint in 2024, which is a major defect requiring immediate replacement. During a test drive, listen for unusual clunking or rattling noises from the front suspension, particularly when negotiating bumps or passing over rough surfaces, as this may indicate further wear in the suspension arms or bushings. Inspect the front suspension for any play or binding, and check for uneven tyre wear patterns that could suggest misalignment or steering issues. The repeated tyre edge wear advisories suggest that the tyres are nearing their legal limits and should be replaced soon to prevent accidents from reduced traction. Additionally, verify that the brake pads and discs, especially the near-side front pads, are still within safe operational limits, as their thinning indicates ongoing friction system wear. Beyond the immediate concerns, the vehicle’s age and mileage warrant a comprehensive inspection of several critical systems. Given the history of tyre wear advisories, conduct a visual and tactile check of the tyre sidewalls for signs of perishing or cracking, which can compromise structural integrity over time. Inspect the front and rear suspension for signs of corrosion, particularly around the ball joints, control arms, and shock absorbers, as standing for extended periods can accelerate rusting. Test the 12V battery and electrical systems, as older vehicles are more prone to battery failure or related issues, especially if the vehicle has been left unused for prolonged periods. Finally, check the fluid levels and condition of the engine oil, transmission fluid, and brake fluid, as these fluids degrade over time and should be replaced according to the manufacturer’s recommended intervals, even if the vehicle has not been driven extensively. A thorough service history check would also be beneficial to confirm that routine maintenance, such as timing belt replacement and fluid servicing, has been completed as specified.
