2024 Mercedes-Benz GLE 300 AMG LN Prem D Mhev 4MA Electric diesel · LM24 YLD

A 2024 Mercedes-Benz GLE 300 d with MHEV mild-hybrid technology is a relatively new vehicle, and as expected for a car of this age, no MOT test results are currently recorded against it in the DVSA database. This is consistent with the UK testing schedule, under which cars first become eligible for an MOT once they reach three years of age. With the vehicle being a 2024 model, it has only just crossed that threshold and will not yet have accumulated a roadworthiness testing record. Any prospective buyer is therefore evaluating a car whose MOT history is effectively blank, meaning there are no recorded failures, pass entries, or advisories to assess for component wear, corrosion trends, or recurring defects. The absence of MOT data at this stage should be treated as neutral information reflecting the vehicle's youth rather than any indication of mechanical condition, and it simply means that no statutory roadworthiness evidence exists yet. The recorded mileage for this vehicle is described as unknown, and there are no MOT test entries against which annual mileage accumulation could be measured. Because the car is only two years old at the time of this assessment, even a relatively high mileage figure would not yet raise the same mechanical concerns that would apply to an older diesel of similar age. For the 2.0-litre turbocharged diesel engine paired with the 48-volt MHEV mild-hybrid system and the 9G-Tronic automatic transmission, mileage context becomes more meaningful once annual figures in excess of fifteen to twenty thousand miles are sustained, as that begins to push component service intervals and wear expectations. Without any recorded odometer readings against the DVSA history, the buyer cannot currently cross-reference wear patterns against usage, and this gap should be addressed by reviewing the Mercedes-Benz digital service history directly. A full and consistent main dealer service record will provide the only reliable insight into how the vehicle has been used so far. For a GLE of this generation, the common areas to inspect during a physical evaluation centre on the suspension geometry, the diesel emissions control system, and the underbody protection associated with the 4MATIC all-wheel-drive platform. The AIRMATIC air suspension, where fitted to higher-trim AMG Line Premium models, should be checked for even ride height at all four corners after the vehicle has been parked for several hours, and any sagging on one corner or a delayed rise on start-up would indicate a failing air spring or air line leak. The front lower suspension arms, anti-roll bar drop links, and the thrust arms should be inspected for perished rubber bushes, particularly given the kerbing damage potential on large-diameter alloy wheels. Steering should feel precise with no shimmy through the wheel under braking, and the vehicle should track dead straight on a motorway stretch with the wheel released briefly, as any pull would suggest geometry issues or a sticking brake caliper. Any knocking from the front end over slow-speed bumps would warrant closer inspection of the subframe bushes and wishbone joints. The diesel powertrain and mild-hybrid system deserve specific attention during a road test. From a cold start, the 2.0-litre OM654 engine should fire promptly and settle into a smooth idle without excessive smoke or diesel clatter, and any blue or white smoke from the exhaust that persists once the engine is warm would point to turbocharger seal wear, AdBlue system faults, or DPF contamination. During the test drive, the 9G-Tronic transmission should deliver smooth, prompt gear changes with no flare between ratios or harsh downshifts under gentle throttle, as any hesitation or judder would suggest mechatronic adaptation issues. The MHEV integrated starter-generator provides torque fill during gear changes, so any noticeable interruption to power delivery would indicate a fault within the 48-volt electrical system or the belt-driven starter-generator unit itself. The brake pedal should feel firm and progressive with no judder through the steering wheel under hard stopping, as warped front discs or pad material transfer would be more noticeable on a heavy SUV of this size. Finally, the buyer should verify the operation of all driver assistance systems, including the Distronic adaptive cruise control and lane keeping assist, as these rely on a correctly calibrated radar sensor behind the front grille and a clean forward-facing camera mounted near the rear-view mirror.
