2005 Mercedes 1628 6.4L Diesel · ST55 MOO

The latest MOT test for the 2005 Mercedes 1628 was successful on 2026-02-13, indicating that the vehicle currently meets the required safety and mechanical standards. However, the recent history shows a mix of passes and a failed test on 2026-02-05, which suggests that while the car has generally remained roadworthy, there have been moments of concern. The overall maintenance trend appears to be stable in recent years, but the high recorded mileage of 282,648 miles over approximately 21 years—about 13,459 miles per year—highlights a significant wear factor. This level of usage is typical for a vehicle of this age, but it does warrant closer inspection of components that experience frequent stress. The mileage figure raises questions about the longevity of critical systems such as the suspension, brakes, and drivetrain. At this rate, components like suspension bushings, coil springs, and binding calipers are likely to show signs of fatigue or degradation, especially if the vehicle has been parked or stood for extended periods. The absence of defects in most recent tests is encouraging, but the cumulative effect of high mileage should not be overlooked. It is advisable to pay particular attention to the tyre condition, checking for any signs of perishing or uneven wear patterns that could indicate improper inflation or alignment issues. For buyers considering this vehicle, the practical advice centers around a thorough pre-purchase inspection. Verify the integrity of the tyre sidewalls for any cracking or perishing, as this is a common failure point at this age. Listen for any unusual clunking noises from the suspension or brakes during a test drive, which could signal worn bushings or disc corrosion. The 12V battery should be tested for health, and the condition of the cooling system should be assessed to rule out overheating risks. Additionally, ensure that all service book stamps are present and that the vehicle has been serviced according to the manufacturer’s calendar. Given the age and mileage, a proactive approach to maintenance will be essential to preserve reliability and avoid unexpected breakdowns.
