2013 Mercedes-Benz ML 3.0L Diesel · MB13 AML

The most recent MOT on 20 August 2026 was passed with no recorded defects, indicating that the vehicle presently meets the statutory safety and emissions standards. Over the past three years the MOT record shows a mixed picture: a failure in October 2025 was confined to lighting faults and an advisory on the front brake disc, while the 2024 and 2026 tests were clean. The recurring advisory on the front brake disc and the earlier CV‑boot deterioration suggest a gradual wear trend, but the absence of any major safety failures in the latest test points to a generally stable maintenance pattern, provided the identified wear items are addressed promptly. At 105,427 miles the ML has averaged roughly 8,100 miles per annum since its 2013 registration, which sits comfortably within the typical usage envelope for a vehicle of this age. There is no evidence of prolonged periods of inactivity that could have accelerated age‑related degradation, nor is there any indication of unusually high mileage that would exacerbate wear on major drivetrain components. Consequently, the mileage itself does not raise immediate red flags, but it does mean that consumables such as brake discs, tyres and suspension bushings are likely approaching the latter stages of their service life. Prospective buyers should give particular attention to the front brake discs, which have been flagged as worn, pitted or scored on two consecutive MOTs. Visually inspect the disc surface for deep scoring, glazing or uneven wear, and listen for any pulsation or shudder through the pedal during a firm braking test, which would indicate that the discs are nearing the end of their useful life. Replacement of the front discs, together with a fresh set of pads, is advisable within the next few thousand miles to avoid a repeat of the 2025 advisory and to maintain optimal stopping performance. The CV‑joint boots on both front drive shafts were recorded as severely deteriorated in 2023; inspect the boots for cracks, oil leakage or grease extrusion, and listen for a clicking or whine on acceleration and deceleration, which would signal joint wear. Re‑sealing or replacing the boots, and checking the joint’s condition, should be undertaken before any loss of drive‑shaft integrity occurs. In addition to the items above, verify that all rear and fog lamps operate correctly, as the 2025 failure highlighted a non‑functioning fog lamp and rear position lamps. Examine the tyre tread depth and sidewall condition; the near‑side front tyre was close to the legal limit in 2023, so all four tyres should be measured for minimum tread and checked for age‑related cracking, especially given the vehicle’s 13‑year lifespan. A thorough check of the battery’s cranking voltage, the condition of suspension bushes and mounts for any looseness or corrosion, and a review of service records for timely oil, coolant and brake fluid changes will help confirm that the ML has been maintained on a calendar basis as well as by mileage. Addressing these points will give the buyer confidence that the vehicle remains roadworthy and that any looming maintenance items are identified before they develop into costly failures.
