2018 Mercedes-Benz CLS 350 D AMG Line Prem + 4M A 2.9L Diesel · J3 MAG

The 2018 Mercedes-Benz CLS 350d AMG Line Premium +4M has maintained a clean MOT history across three consecutive tests, with the most recent inspection on 30 January 2025—just six months prior to today’s date. This places the vehicle within the DVSA’s recommended 12-month MOT cycle, though it is slightly overdue by a minor margin. No defects were recorded in any of the tests, suggesting the vehicle has not experienced recurring mechanical or structural issues that would necessitate early failure. The absence of advisories or advisory notes further indicates that no critical components were deemed borderline or in need of imminent attention during these tests. The recorded mileage progression of 63,427 miles today, with tests at 39,308 miles in September 2022 and 50,147 miles in December 2023, reflects a consistent annual average of approximately 7,900 miles. This rate is typical for a vehicle of this age and model, neither excessively high nor low, and there are no evident gaps or abrupt jumps in mileage that would raise suspicion of neglect or tampering. The regular intervals between tests align with standard usage patterns, though a buyer should verify whether the vehicle has undergone any non-MOT-related servicing or repairs outside this record. Given the clean MOT history, the primary focus for an in-person inspection should centre on high-wear components that are not routinely tested under the MOT regime. The suspension system—particularly the rear coil springs, bushes, and dampers—should be examined for uneven wear, fluid leaks, or excessive play, as diesel-powered AMG Line models often experience accelerated suspension degradation due to weight and performance tuning. Brake components, including rear calipers and discs, warrant scrutiny for binding or uneven wear, as the MOT does not test for subtle performance issues beyond basic functionality. Additionally, the underbody should be inspected for corrosion around the sills, wheel arches, and exhaust system, as diesel vehicles are prone to rust acceleration in these areas over time. The lack of MOT advisories does not preclude the possibility of hidden issues, so a thorough check of the turbocharger and intercooler—critical for the 3.0-litre diesel engine—is advisable. Oil consumption patterns, though not recorded, can indicate internal wear, so confirming the last oil change and its interval is essential. Finally, the 4M all-wheel-drive system should be tested for proper engagement and any warning lights, as drivetrain faults are not always captured in standard MOT testing. While the vehicle’s roadworthiness appears stable based on available data, these areas demand closer attention to ensure long-term reliability.
