2004 Mercedes-Benz ML 2.7L Diesel · WR54 AHC

A safety‑critical fault in the supplemental restraint system was recorded in July 2022, forcing a failure, yet the vehicle cleared a subsequent MOT a month later, showing that the air‑bag warning lamp issue and the damaged rear bumper were remedied to the examiner’s satisfaction. Apart from that incident, the remaining entries are advisory only, suggesting no further outright failures have been logged since the August 2022 pass. At 134,228 miles on a 2004 model the average annual distance works out to roughly 6,100 miles, which sits squarely within normal usage for a vehicle of this age. The mileage does not indicate any periods of prolonged inactivity, but the relatively modest accumulation means wear on consumables such as suspension joints, shock absorbers and tyres will be progressing at a typical rate rather than being accelerated by high‑kilometre abuse. The ball‑joint play noted on the near‑side rear lower suspension should be inspected for any clunking or uneven tyre wear when cornering or traversing bumps; excessive play may manifest as a vague knocking sensation from the rear wheel arch. The light oil misting on the near‑side rear shock absorber warrants a visual check for dampness around the damper and a feel for reduced damping firmness during a drive, as oil leakage can precede loss of ride control. The off‑side rear bumper that was previously deemed hazardous must be examined for proper mounting and any residual deformation that could affect rear‑impact protection. Finally, verify that the air‑bag warning lamp remains extinguished after the engine is started and that the dashboard shows no residual SRS codes, as intermittent faults can reappear. Confirm that the near‑side obligatory mirror has been replaced or repaired, and that the spare tyre is fully inflated and free of damage before relying on it. A thorough test‑drive focusing on steering response, brake feel and any unusual noises will help reveal whether the suspension and shock components are still within safe operating limits. If any of these items raise concerns, factor the cost of remedial work into your purchase decision.
