2005 Mercedes Vaneo 1.7L Diesel · HG55 FZM

The most recent MOT in October 2024 at 64,690 miles passed without defects, but this follows a clear pattern of worsening mechanical and structural issues over the past two years. The July 2024 failure alone revealed serious concerns: binding rear brakes, severely deteriorated CV joint boots, corroded brake pipes and hoses, and critically, a seriously weakened rear sub-frame —a structural compromise that demands immediate attention. Earlier failures in June 2023 and 2024 also highlighted persistent oil leaks, worn suspension bushes, and tyres run to the legal limit, suggesting a vehicle that has been neglected rather than systematically maintained. The fact that the rear anti-roll bar bushes were flagged as excessively worn in 2024—after being merely worn in 2023—indicates progressive deterioration in key load-bearing components. While the October 2024 pass is encouraging, it’s likely the result of temporary fixes rather than a resolution of underlying problems, particularly given the severity of the corrosion and binding brake issues documented just three months prior. The van’s mileage of 64,690 over 21 years—averaging just 3,080 miles annually—is unusually low, raising questions about whether it has been stored for extended periods or driven sparingly. The gap between the 2022 MOT (58,841 miles) and the first 2023 test (62,345 miles) suggests a roughly 3,500-mile interval over nine months, which is unusually high for such low annual usage. This inconsistency implies either sporadic driving or, more likely, a history of being left unused for long stretches, accelerating corrosion and component degradation. The lack of mileage accumulation also means wear items like tyres, brakes, and suspension have had prolonged exposure to moisture and environmental stress without the mitigating effect of regular motion. For any prospective buyer, the rear sub-frame corrosion—described as seriously weakened in July 2024—must be the top priority. This is not a minor advisory; it directly impacts structural integrity and safety. The binding rear brakes and deteriorated CV joint boots should also be inspected immediately, as these are failure points that could escalate into more expensive repairs if ignored. The repeated failures of rear anti-roll bar bushes and the progression from worn to excessively worn state in just a year signal that the suspension geometry is compromised, potentially leading to uneven tyre wear or handling issues. Finally, the corroded brake pipes and hoses—covered in grease and twisted—demand a thorough check for fluid leaks or hydraulic inefficiency, as these can compromise braking performance. Given the vehicle’s age and the severity of the structural and mechanical faults documented, a pre-purchase inspection by a Mercedes-Benz specialist is strongly advised to assess whether the issues have been addressed or if they represent a costly long-term liability.
