2009 Mercedes-Benz ML 3.0L Diesel · AY58 HLV

The 2009 Mercedes-Benz ML presents a stable mechanical trend, though its recent testing history reveals an unusual pattern. The most recent test on 2025-07-08 at 92,951 miles passed with zero defects, yet this follows a recurring cycle of failing the MOT and passing a fortnight later. In June 2024, the vehicle failed at 89,489 miles and passed at 89,493 miles just fifteen days later. The same scenario occurred in June 2023, failing at 85,526 miles and passing at 85,542 miles two weeks after. Critically, the record lists no defects for either the failures or the subsequent passes. This suggests the initial failures likely stemmed from procedural or administrative issues rather than significant mechanical faults requiring repair. The mileage accumulation is remarkably low for a seventeen-year-old vehicle, averaging roughly 5,468 miles annually. Between July 2023 and June 2024, the odometer moved just 3,967 miles, and from June 2024 to July 2025, it covered a mere 3,458 miles. Such minimal use indicates the ML has spent prolonged periods stationary. While low mileage reduces wear on consumables like brake discs and drivetrain components, extended sitting introduces its own risks. A buyer must recognize that this vehicle's condition is dictated more by age and inactivity than by road use. Given the anomalous fail-pass history and the extremely low annual mileage, a physical inspection must focus on the deterioration caused by standing. Examine the tyres closely for sidewall cracking and flat-spotting, as infrequent use degrades rubber faster than driving does. Inspect the brake calipers and discs for corrosion and binding, a common issue when vehicles sit unused. The suspension bushes and coil springs require scrutiny for perishing, and the exhaust system needs checking for internal rust caused by condensation buildup during short runs. Finally, assess the underbody and structural mounts for corrosion, as the ML-Class is susceptible to rust when left dormant in damp conditions.
