2001 Mercedes-Benz ML 2.7L Diesel · Y128 BAW

A dominant feature of this ML’s MOT history is the repetition of safety‑critical defects – notably a steering rack with excessive free play recorded in December 2023, multiple failures of the supplementary restraint system (SRS) warning lamp across 2021‑2023, and recurring brake‑related issues such as significantly worn front discs and corroded rear brake pipe. The most recent test on 14 December 2023 was a pass, but it still carried advisories for an exhaust noise, seat‑belt webbing wear and the persistent SRS lamp illumination fault, indicating that the underlying problems have not been fully resolved. At 156 470 mi the vehicle averages roughly 6 250 mi per year, a usage rate that sits comfortably within normal expectations for a 25‑year‑old Mercedes‑Benz ML. The MOT chronology shows regular annual testing from mid‑2020 through 2023 with no prolonged gaps, suggesting the mileage has been accumulated under typical operating conditions rather than long periods of storage. Nevertheless, the cumulative distance means that wear items such as suspension bushings, drivetrain bearings and brake components will be approaching the end of their design life and should be inspected for excessive play, leakage or corrosion. When you inspect the car, pay particular attention to the steering feel – a loose or wandering wheel, especially under light‑touch steering, could confirm the rack free‑play noted in the latest MOT. Verify that the air‑bag warning light illuminates correctly on ignition; a persistent off lamp signals a fault in the SRS circuitry that may require module replacement or wiring repair. Examine the engine and gearbox oil bays for any sign of seepage, as the record lists non‑excessive leaks on several occasions; even minor drips can indicate deteriorating seals that may worsen under load. The front brake discs should be measured for thickness and inspected for scoring, while the rear brake pipe should be checked for rust, cracking or grease buildup, all of which were flagged as corroded in earlier tests. Finally, confirm that all external lighting functions correctly – the high‑beam headlamp on the roof, the rear fog lamp and both headlamp lenses were previously recorded as defective, and mis‑aimed beams can be a safety hazard at night. Listen for any exhaust rattles that may stem from the reported noisy exhaust, and inspect the off‑side front seat‑belt webbing for fraying that could compromise restraint performance. A comprehensive mechanical inspection covering steering, brakes, SRS electronics, oil seals and lighting will be essential before committing to purchase.
