2015 Mercedes-Benz ML350 AMG Line Prem+ Bluetec A 3.0L Diesel · PK10 MOM

This Mercedes-Benz ML350 AMG Line has maintained a clean MOT history with no defects or advisories across the most recent three tests, including the January 2026 pass at 123,359 miles. The absence of recurring issues suggests that major mechanical or structural failures have been avoided, though the lack of advisories does not preclude hidden wear or deferred maintenance. The most recent test occurred just six months ago, which is acceptable but not ideal—anything beyond a year without an MOT introduces greater uncertainty about unchecked components like suspension bushes, coil springs, or binding calipers. The vehicle’s roadworthiness remains stable in the short term, but the extended gap since the last test means a thorough inspection is essential before purchase. The recorded mileage of 123,359 miles over approximately 11 years reflects a steady usage pattern of around 11,200 miles annually, which is typical for this age and model. There are no abrupt jumps or prolonged inactivity periods between tests, though the gap between the 2022 and 2023 tests (three months) is unusually short compared to the usual 12-month interval. This could indicate either proactive servicing or a deliberate attempt to meet MOT deadlines without addressing underlying wear. The lack of mileage gaps also suggests the vehicle has not been left unused for extended periods, which might have led to fluid degradation or component deterioration. Given the clean MOT record, a buyer should prioritise an independent inspection of high-wear items such as suspension bushes, particularly the rear trailing arms and control arms, which often fail in this model after 100,000 miles. The absence of advisories does not confirm their condition, so visible cracks or excessive play in these components would be critical. Brake discs and pads should be checked for uneven wear or glazing, as the AMG Line’s performance braking demands accelerated wear. Additionally, the exhaust system—especially around the catalytic converter and turbocharger—should be scrutinised for corrosion or leaks, as diesel vehicles of this age are prone to such issues. Finally, the engine bay fluids (oil, coolant, differential fluid) should be inspected for contamination or leakage, as these are often overlooked until failure occurs.
