2022 Mercedes-Benz GLE 350 AMG Line Prem+ DE 4M A 1.9L Electric diesel · LM22 OOV

This 2022 Mercedes-Benz GLE 350d AMG Line presents a notably clean mechanical profile, with a single MOT pass on record at 59,173 miles and zero advisories or defects logged. Such an unblemished result on a premium SUV of this size and complexity suggests that, at least at the point of test, the braking system, suspension geometry, steering components, emissions output, and structural underside were all within prescribed limits. While a single clean test cannot guarantee long-term durability, the absence of any flagged items on a vehicle approaching four years old and past the half-century mileage mark is reassuring, particularly given the higher-than-average usage the car appears to have seen. At 59,173 miles over approximately four years, the GLE has accumulated around 14,800 miles annually, which sits well above the typical 8,000 to 10,000 mile average for a UK-registered vehicle. This higher rate of accumulation means the drivetrain, particularly the 2.0-litre diesel engine, nine-speed automatic transmission, and integral 4MATIC all-wheel-drive system, has been worked more consistently than a lower-mileage example. Consumables such as brake pads, discs, tyres, and the diesel particulate filter will likely have experienced more wear cycles, and diesel-specific components like the AdBlue system, turbocharger, and dual-mass flywheel warrant closer scrutiny than they would on a sparingly driven car. The mileage progression is steady and consistent, with no anomalous gaps or sudden jumps that would suggest prolonged standing periods or clock irregularities. For a prospective buyer, a thorough physical inspection should focus on the areas most likely to show wear given the mileage. On a test drive, listen for any clonking or knocking from the front suspension, particularly over uneven surfaces, as worn lower control arm bushes, anti-roll bar drop links, and front coil springs are common failure items on the GLE platform regardless of MOT outcome. Check for steering vagueness, pulling to one side under braking, or vibration through the steering wheel, which could indicate warped front brake discs or uneven pad wear, both of which are prevalent on heavier diesel variants. Examine the underside for any early signs of corrosion around the rear axle assembly, brake pipe runs, and exhaust mounting points, paying particular attention to the area around the AdBlue tank and dosing module for any crystallised residue that could point to a failing SCR system. Given the diesel powertrain, cold-start behaviour deserves close attention. Listen for any excessive smoke on ignition, timing chain rattle, or rough idle that could indicate injector wear or stretched timing components, which are known cost items on this engine family. Confirm that the automatic transmission shifts smoothly through all gears, particularly during kickdown, and that there is no hesitation, flare, or harsh engagement. Finally, verify the service history in detail, ensuring that diesel-specific maintenance such as AdBlue top-ups, DPF forced regenerations, and EGR valve cleaning have been addressed at the correct intervals, as neglect in these areas on a high-mileage premium diesel can lead to disproportionately expensive repairs relative to the purchase price.
