2015 Mercedes-Benz E 2.1L Diesel · WG65 AAU

The most recent DVSA MOT test on the 2015 Mercedes-Benz E was conducted on 2026-06-03 and resulted in a pass, though it included two persistent advisories regarding brake pad wear—both front and rear—classified as ‘1.1.13 (a) (ii)’ under the DVSA’s criteria. These advisories indicate that the friction materials on both sets of brake assemblies are approaching the minimum safe thickness, which, while not failing the vehicle outright, demands immediate attention to prevent reduced braking effectiveness and potential failure during critical stops. The absence of failures in the intervening three MOTs suggests a stable maintenance record, but the recurring advisories highlight a pattern that should not be overlooked. The vehicle’s consistent passing of tests despite these advisories implies that the owner has either been proactive in addressing pad replacement or that the current pads are still functional in the short term, though this is not a sustainable long-term solution. The recorded mileage of 185,034 miles for a vehicle aged approximately 11 years represents a high annual usage rate of around 16,821 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, tyres, and suspension components, as well as on drivetrain elements such as clutches, gearbox fluids, and exhaust systems. The lack of significant mileage gaps between MOT tests suggests consistent driving habits, which could imply either heavy use or a lack of long periods of inactivity that might otherwise mitigate wear. However, the high mileage alone does not explain the recurring brake pad advisories, which may indicate that the vehicle’s braking system has been subjected to excessive stopping or has been under-repaired in the past. A deeper inspection of service records would be prudent to determine whether brake pad replacements were scheduled or if the advisories were ignored. Given the recurring brake pad advisories, the prospective buyer should prioritise a thorough inspection of the braking system during the inspection period. Visually inspect the brake discs for signs of glazing, warping, or corrosion, particularly on the rear, where the advisories are noted. Listen for any unusual noises during braking—such as squeaking, grinding, or a vibration that may indicate uneven pad wear or binding calipers. Check the brake fluid level and condition in the master cylinder reservoir, as low fluid or contamination can exacerbate brake performance issues. If the pads are confirmed to be worn to the minimum safe thickness, immediate replacement is essential, ideally with new discs to prevent damage from metal-to-metal contact. Additionally, verify that the brake hoses and lines are free of leaks or cracks, and that the parking brake is functioning correctly, as a poorly adjusted or worn rear brake system can lead to binding and further wear. Beyond the brakes, the buyer should conduct a comprehensive inspection of the vehicle’s suspension and tyres, given the high mileage. Examine the suspension components for signs of wear, such as cracked or swollen coil springs, worn suspension bushes, or excessive play in the control arms or struts. Look for uneven tyre wear patterns, which could indicate misalignment, suspension issues, or incorrect tyre pressures. The tyres should also be checked for sidewall cracking or perishing, which can occur over time regardless of mileage, especially in older vehicles exposed to UV radiation. Given the vehicle’s age and usage, a check of the 12-volt battery and associated electrical systems is advisable, as prolonged inactivity or high mileage can lead to battery degradation or parasitic drain issues. Finally, since the vehicle has not undergone a full service in recent years, the buyer should confirm the last recorded service date and ensure that time-based fluid servicing—such as the gearbox, differential, and coolant—has been attended to, as these fluids degrade over time regardless of mileage. If the service book is missing or unclear, a professional inspection to verify the vehicle’s maintenance history is strongly recommended.
