2013 Mercedes-Benz ML350 AMG Sport Bluetec Auto 3.0L Diesel · LFZ 1

A flawless MOT record across four consecutive tests, with the most recent pass on 13 July 2025 carrying no advisories or defects, presents a vehicle with a strong and uninterrupted roadworthiness profile. The absence of any recorded advisories is particularly noteworthy for a thirteen-year-old Mercedes-Benz, as it removes the usual indicators of wear items approaching their service limits. For a prospective buyer, this clean sheet suggests the chassis, lighting, braking, exhaust, and suspension systems have all been maintained to a pass standard at each annual assessment, with no flagged deterioration in components that typically accumulate minor defects over time. With 101,854 miles accumulated over roughly thirteen years, this ML350 averages around 7,835 miles annually, which sits comfortably within typical parameters for a large luxury SUV of this vintage. There are no significant gaps in the MOT history to suggest extended periods off the road, and the consistent year-on-year testing indicates a vehicle that has remained in regular use throughout its life. Mechanically, this steady usage pattern tends to be kinder to drivetrain components than low-mileage examples left standing for long periods, particularly for the diesel engine, turbocharger, and seven-speed automatic transmission, all of which benefit from regular thermal cycling. The BlueTec system, however, does demand attention to its AdBlue injector, NOx sensors, and SCR catalyst regardless of mileage, so verification of any warning lights or dashboard messages remains essential. Although no specific components have been flagged by testers, the buyer should still prioritise a targeted inspection of items that frequently affect this generation of M-Class. The air suspension system, if fitted, is a known area for air spring failure and compressor wear, so listen during a test drive for any sagging at the rear when stationary and for the compressor running excessively or failing to maintain ride height. The front suspension wishbones, anti-roll bar bushes, and drop links should be checked for knocking or clonking over uneven surfaces, as these are common wear points on vehicles of this age and weight. Steering response should remain precise without vagueness around the centre point, and any fluid weep from the power steering rack or front differential warrants close inspection. On the braking side, although no defects have been recorded, the discs and pads should be physically inspected for wear given the vehicle's mass and accumulated mileage. Test from a steady speed for any judder through the steering wheel, which would indicate warped front discs, and verify that the parking brake holds firmly on an incline, as the electronic parking brake actuators can require recalibration. The diesel drivetrain should be observed from cold for excessive smoke, particularly blue haze on startup indicating oil consumption issues, and the transmission should shift smoothly through all ranges without harsh engagement or hesitation. Finally, a thorough underbody inspection for corrosion remains advisable given the age, particularly around the subframe mounting points, brake lines, and exhaust hangers, even though none of these areas have yet prompted an advisory.
