2014 Mercedes-Benz E 2.1L Diesel · PB63 APR

The most recent MOT test on the 2014 Mercedes-Benz E conducted on 2026-06-23 resulted in a pass, though it included an advisory regarding the offside rear tyre’s wear pattern—specifically, that it is worn close to the legal limit and exhibits edge wear, which can indicate uneven loading or excessive lateral forces. Analysing the broader MOT history reveals a pattern of recurring advisories on brake pad wear, particularly in 2022 and 2023, alongside a single major failure in 2022 for a non-functioning offside side repeater. While the vehicle has passed subsequent tests, the persistence of brake-related advisories suggests ongoing or developing issues that warrant closer attention, especially as the pads continue to thin. The presence of multiple minor faults in prior years, including headlamp alignment and repeater issues, also indicates that the vehicle may have had intermittent mechanical or electrical challenges, though the latest test suggests these have been resolved or are no longer active. The recorded mileage of 96,941 miles for a vehicle aged approximately 12 years represents an average annual usage of around 8,078 miles, which is consistent with typical driving patterns for this age group. However, the absence of a service history or detailed mileage gaps makes it difficult to determine whether this reflects regular, moderate use or periods of prolonged inactivity, which can accelerate wear in certain systems. For example, standing for extended periods can lead to brake disc corrosion or binding calipers, while low-mileage conditions might mask underlying issues until more significant wear occurs. The combination of moderate mileage and the vehicle’s age means that consumables like brake pads, tyres, and suspension components may be approaching or exceeding their expected lifespan, necessitating a thorough inspection to assess wear progression and potential hidden damage. Given the recurring advisories on brake pad wear and the recent tyre edge wear, the prospective buyer should conduct a meticulous inspection of the braking system. On a test drive, listen for unusual grinding noises when applying the brakes, as this could indicate metal-to-metal contact between pads and discs, which may require immediate attention. Inspect the brake discs for uneven wear, grooves, or signs of glazing, and check for any binding or excessive play in the calipers. Additionally, visually inspect the brake fluid reservoir for contamination or fluid degradation, as this can lead to brake failure. The offside rear tyre’s edge wear suggests the vehicle may have been subjected to lateral forces, potentially from rough roads or misaligned suspension, so verify that all suspension components—such as coil springs, shock absorbers, and suspension bushes—are functioning correctly, with no excessive clunking or bouncing when driving over bumps. For the tyre advisories, the buyer should replace the offside rear tyre immediately, as edge wear can compromise tyre integrity and increase the risk of blowouts. Prioritise the replacement of the near-side rear tyre, which also shows similar wear patterns, to maintain even tyre loading and prevent premature failure. Beyond the brakes and tyres, the buyer should check for signs of tyre sidewall perishing or cracking, which can occur even at moderate mileage due to age-related degradation of the rubber compound. Inspect the vehicle’s undercarriage for signs of oil leaks, particularly around the engine bay, transmission, and differential, as well as for corrosion on the exhaust system, which may indicate rust or structural weakness. Finally, given the vehicle’s age, test the 12-volt battery’s health by ensuring it holds a charge and that all electrical systems operate without hesitation. Additionally, verify that the service book or maintenance records include details of fluid changes, such as brake fluid, coolant, and transmission fluid, as these should have been serviced in line with the manufacturer’s recommendations—typically every 60,000 to 100,000 miles or every 2 to 3 years, respectively. If no service history is available, consider a comprehensive fluid check and replacement to mitigate risks of premature failure.
