2005 Mercedes - 4.3L Diesel · HFZ 8469

The vehicle currently holds a roadworthy status, though the maintenance history reveals a pattern of intermittent compliance. The most recent test in September 2023 at 397,248 miles resulted in a failure with no specific defects recorded in the log, suggesting a mechanical or emissions-related failure that was rectified. Despite this failure, the clean passes in 2021 and 2022 indicate that when the vehicle is maintained to standard, it remains capable of meeting basic safety and environmental requirements despite the extreme stress on its components. The mileage profile is exceptionally high, totaling nearly 400,000 miles over 21 years. This averages to approximately 19,000 miles per annum, with a significant surge noted between April 2021 and June 2022, where the vehicle covered 21,630 miles in just 14 months. This rapid accumulation suggests heavy consistent use, which accelerates the degradation of the drivetrain and rubber suspension components. The gap between the 2019 and 2021 tests shows a period of lower usage, but the overall trend points to a high-duty cycle vehicle. A buyer must prioritise a thorough physical inspection of the chassis for structural corrosion. Given the high mileage, the suspension bushes, coil springs, and shock absorbers are likely nearing the end of their functional life. The braking system should be checked for binding calipers and excessive wear on the discs, as high-mileage operation puts immense strain on these components. Because the MOT record does not list specific advisories, it is vital to look for signs of weeping oil leaks or perished engine mounts that have not yet triggered a test failure but indicate advanced mechanical wear.
