2020 Mercedes-Benz E 400 AMG LN NGT ED Prm+d 4M A 2.9L Diesel · 7 PJG

The vehicle maintains a roadworthy status, but the maintenance record shows a worsening trend regarding the front suspension geometry. While the car passed its June 2025 test at 44,219 miles, the tester identified slight play in both the nearside and offside front suspension arm ball joints. This follows an advisory from the June 2024 test at 38,965 miles, where only the nearside joint was flagged. The progression from a single affected side to both indicates these components are reaching the end of their service life. The mileage pattern is consistent with a low-use vehicle, averaging approximately 7,370 miles per year over its six-year tenure. Between the June 2023 test at 31,237 miles and the June 2024 test, the car covered 7,728 miles, suggesting steady annual usage. This low mileage generally reduces the strain on the drivetrain, though it can sometimes lead to the degradation of rubber bushings and ball joints despite the low odometer reading. A buyer must conduct a thorough physical inspection of the front suspension assembly to assess the extent of the ball joint play. Since this issue has appeared in two consecutive years, it is likely that the components require immediate replacement to prevent further steering inaccuracies or unpredictable handling. The inspection should also check for signs of uneven tyre wear, which often accompanies worn ball joints in high-performance Mercedes models. No structural corrosion or brake failures were noted in the history, focusing the mechanical concern entirely on the front-end wear components.
