2018 Mercedes-Benz E 3.0L Petrol · LS68 HFM

The MOT record for this 2018 Mercedes-Benz E-Class is largely one of consistent roadworthiness, with six consecutive pass certificates and no recorded failures since first testing eligible, including three clean tests in 2022, 2023, and 2024. The most recent assessment on 18 August 2026 maintains that pass status but introduces two advisories that warrant attention before purchase. The first flags a fractured road wheel bridge over the valve on the offside front, a structural concern on the wheel itself that could compromise tyre seating and balancing, while the second notes that offside rear parking brake efficiency only just met the minimum standard and that the braking system requires adjustment or repair. Neither advisory constitutes a failure at present, but the parking brake item in particular suggests the rear caliper mechanism, cable, or adjusters may be approaching the point of requiring mechanical intervention. Against an age of approximately eight years, the recorded mileage of 69,393 miles equates to an annual accumulation of around 8,674 miles, which is broadly typical for a vehicle of this class and indicates consistent regular use rather than long periods of standing or unusually high motorway accumulation. This kind of usage pattern is generally favourable for a Mercedes-Benz of this vintage, as it tends to keep seals, brakes, and suspension components working through their intended duty cycles rather than suffering from the dried-out rubber and stagnant fluids associated with low-mileage or stored vehicles. The test history shows annual submissions from 2021 through 2026 with no gaps, confirming continuous use and presentation for inspection throughout the recorded period. The advisory relating to the offside front road wheel should be addressed before the vehicle is used, as a fractured wheel at the valve bridge can lead to gradual air loss, vibration at speed, and in a worst case wheel failure. A prospective buyer should physically inspect the wheel for any visible crack, deformation, or previous weld repair, and confirm whether the wheel has been replaced or refurbished since the test. On a road test, listen for any rhythmic thumping or steering tremor that becomes more pronounced at higher speeds, as this can indicate a compromised wheel that has not been properly resolved. If a replacement is required, ensure it matches the correct Mercedes-Benz specification for the E-Class, including offset, centre bore, and load rating. The parking brake advisory points to a marginal rear brake balance issue, most likely at the offside rear caliper, handbrake mechanism, or adjuster. On inspection, the buyer should attempt to apply the handbrake on a slight incline and count the number of clicks, as a properly adjusted system typically engages within three to five clicks; excessive travel or failure to hold the vehicle suggests the adjusters or rear caliper mechanism require attention. During a road test, apply the brakes firmly from speed and listen for any grinding, squeal, or pulling to one side, particularly under light pedal pressure where a binding or partially seized caliper often first manifests. Given the vehicle's age and mileage, it would also be prudent to inspect the condition of the brake discs and pads directly, as wear items may now be approaching the point of replacement regardless of what the MOT test recorded.
