2023 Mercedes-Benz E 300 AMG LN NGT ED PRM + DE A 1.9L Electric diesel · KT23 LVR

The most recent DVSA MOT test for this 2023 Mercedes-Benz E 300 AMG Line Night Edition Premium Plus diesel automatic was conducted on 3 November 2025, and the vehicle passed with no advisories or defects recorded against it. This represents the only MOT entry on file, which is consistent with a vehicle that was first registered in 2023 and therefore only recently reaching the three-year threshold at which its first statutory roadworthiness examination becomes due. On the strength of the available data, the maintenance trend can only be described as stable and uneventful; there are no historical failure points or advisories to suggest any worsening trajectory, but equally there is insufficient longitudinal history to confirm an improving trend. The clean pass is encouraging but should be read in the context of a relatively new vehicle that has not yet been subjected to multiple test cycles, and buyers should not treat it as definitive proof of long-term mechanical condition. The recorded mileage of 49,083 miles over an approximate three-year ownership period equates to an annual accumulation of around 16,361 miles, which is notably higher than the UK national average. This level of usage points to a vehicle that has predominantly been used for longer-distance or mixed-condition driving, such as motorway commuting or commercial fleet operation, rather than purely urban short journeys. Mechanically, higher annual mileage accelerates wear on consumable items including brake pads and discs, tyres, drive belts, and certain drivetrain components, and brings forward major service intervals such as timing chain replacement, automatic transmission fluid and filter changes, and Diesel Particulate Filter loading cycles. Buyers should also be alert to the possibility of consistent high-load use without adequate warm-up periods, which can contribute to issues such as premature turbocharger wear or increased oil consumption, particularly in diesel powertrains. Given the clean MOT history and the absence of any recorded advisories, the third-party test record does not flag any specific components for immediate scrutiny, and a physical inspection should therefore focus on age-and-mileage-appropriate wear items that fall outside the strict MOT pass/fail criteria. Tyres should be examined closely for tread depth, uneven wear patterns across the axle which could indicate tracking or suspension misalignment, and importantly for any signs of sidewall perishing or cracking, as high-mileage tyres can degrade structurally even when tread remains adequate. The 12V auxiliary battery should be tested for state of health, as modern Mercedes-Benz vehicles place considerable parasitic load on the battery through security systems and telematics, and a weakened battery can cause a cascade of electrical faults. Brake discs should be inspected for lipping, hot spots, or corrosion between the disc and caliper, particularly given that diesel variants of this class are heavy and generate substantial thermal mass during deceleration. On a test drive, the buyer should listen for any suspension clonks over speed humps or uneven surfaces, which would indicate degraded anti-roll bar bushes or top mount wear, and check for any pulling under braking that could suggest warped front discs or binding calipers. Finally, attention should be directed towards time-based fluid and component servicing that may not be fully captured in routine maintenance schedules. Diesel fuel systems are particularly sensitive to water ingress and microbial contamination if the vehicle has been left standing for extended periods, so the condition of the fuel filter and any water separation warnings should be confirmed. Engine oil and filter changes on Mercedes-Benz diesel models are typically required at manufacturer-specified intervals tied to either time or mileage, and any service history should be cross-referenced to ensure these have been completed using the correct MB 229.52 or equivalent specification oil. The AdBlue system, Diesel Particulate Filter, and exhaust gas recirculation components should be verified as functioning correctly, as these are common failure areas on higher-mileage diesel executive cars and can attract premium repair costs. A thorough pre-purchase inspection by a Mercedes-Benz specialist or independent German marque expert is strongly recommended, including a diagnostic scan using STAR Diagnosis or an equivalent system to identify stored fault codes that would not be detected during a standard road test or visual MOT examination.
