2019 Mercedes-Benz X350 Power D 4MATIC Auto 3.0L Heavy oil · RF68 FVK

The most recent MOT test on 2024-09-05 confirms the vehicle passed with no recorded defects at 68,876 miles, following an unusually close retest just one day prior that also failed without any noted issues. This pattern of consecutive tests without faults suggests the vehicle has not experienced any recurring or serious mechanical failures, though the lack of advisories or defects in any of the four recorded tests makes it impossible to identify hidden wear or deferred maintenance. The clean history implies either consistent upkeep or that the vehicle has not yet reached the typical wear thresholds for its age and mileage. The mileage progression shows a steady accumulation of approximately 9,800 miles annually, which aligns with typical usage for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, though the 2023-2024 period saw a notable 21,454-mile increase over 15 months—slightly above the average—potentially indicating heavier usage during that time. The absence of any advisories or defects in the most recent tests suggests the owner did not delay servicing due to mileage concerns, though this does not guarantee all service intervals were adhered to. Given the lack of recorded defects, a buyer should prioritise an independent inspection of high-wear components that often fail beyond MOT thresholds. The suspension system—particularly the rear coil springs and bushes—should be examined for uneven sagging or excessive play, as 68,876 miles on a 2019 model approaches the typical lifespan for these parts. Brake components, including the rear calipers and discs, warrant scrutiny for binding or uneven wear, especially if the vehicle has experienced rapid mileage accumulation. Additionally, the 4MATIC drivetrain’s differentials and transfer case should be checked for fluid leaks or unusual noise, as these are less likely to be caught in a standard MOT. Structural corrosion, particularly around the wheel arches, sills, and underbody, should also be assessed, as this is a common failure point for Mercedes-Benz models of this era.
