2019 Mercedes-Benz CLS 350 D AMG Line Prem + 4M A 2.9L Diesel · EC07 MJC

This Mercedes-Benz CLS 350 d AMG Line demonstrates a stable roadworthiness profile based on the most recent MOT test, which passed without defects on 2025-01-09. The absence of advisories or failings in either of the two recorded tests suggests no recurring mechanical issues have been formally identified by the tester. However, the 19-month gap between the 2023-12-23 and 2025-01-09 tests—despite low mileage—raises questions about whether intermediate maintenance was overlooked. The lack of advisories does not preclude hidden wear; critical components like turbocharger seals, differential fluid, or suspension bushes may still require inspection given the vehicle’s diesel powertrain and age. The recorded mileage of 28,717 miles over approximately seven years equates to an average of just 4,102 miles annually, which is unusually low for a vehicle of this class. This suggests either minimal use or prolonged periods of inactivity, both of which can accelerate degradation of fluids, seals, and suspension components. The sparse MOT history—only two tests—does not provide a clear trend, but the extended gap between tests could indicate inconsistent servicing. Buyers should verify if the vehicle has undergone regular oil changes, turbo servicing, and suspension checks, as these are often neglected in low-mileage vehicles. Given the lack of MOT advisories, the primary focus for an in-person inspection should centre on high-risk areas for diesel engines and luxury vehicles. The turbocharger and intercooler should be examined for oil leaks or carbon buildup, as these are common failure points in AMG diesel units. Suspension components—particularly the rear multi-link bushes and coil springs—should be checked for cracking or excessive play, as these are prone to fatigue over time despite low mileage. Additionally, the rear brake system, which has not been flagged in tests, warrants scrutiny for binding calipers or worn pads, especially if the vehicle has been stationary for extended periods. Structural integrity of the underbody and wheel arches should also be assessed for corrosion, as diesel exhaust fumes can accelerate rust in these areas.
