2004 Mercedes-Benz E 2.1L Diesel · AF04 XTJ

The most recent MOT test on the 2004 Mercedes-Benz E occurred in April 2025 and resulted in a clean pass, with only minor issues related to the windscreen and trailer electrical socket, alongside several advisories concerning engine and underbody covers. This follows a pattern of fluctuating outcomes, with multiple failures over the past three years, particularly in 2023 and 2024, where major defects were identified in the suspension components, brake pipes, steering system, and structural integrity of the sub-frame. While the latest test shows stability, the historical record suggests a concerning trend of progressive wear and potential underlying issues that have not yet reached critical failure points. The advisories from earlier tests—such as excessive play in track rod ball joints and minor tyre damage—highlight areas where maintenance may have been deferred or where wear is accelerating beyond routine expectations. The vehicle’s recorded mileage of 196,617 miles over approximately 22 years represents an average annual usage of around 8,937 miles, which is relatively typical for a car of this age and class. However, the combination of high mileage and the documented wear patterns suggests that the vehicle has undergone significant mechanical stress, particularly in the suspension, drivetrain, and braking systems. The presence of multiple major failures in 2023 and 2024, including corroded brake pipes and severely worn sub-frame bushes, indicates that the vehicle may have been subjected to heavy or inconsistent driving conditions, leading to accelerated wear. The gaps between MOT tests—such as the two-year interval between 2022 and 2024—could also imply periods of prolonged idleness, which can exacerbate corrosion and fluid degradation in components like brake systems and exhaust hoses. Buyers should be aware that this combination of mileage and maintenance history may necessitate more frequent and thorough inspections to mitigate the risk of sudden, costly failures. Given the historical MOT failures and advisories, the prospective buyer should conduct a meticulous pre-purchase inspection with a focus on the suspension, steering, and braking systems. Start by examining the front and rear suspension for signs of excessive play in the track rod ball joints, which were flagged in multiple tests, particularly in 2022 and 2024. Listen for clunking noises during cornering or when driving over bumps, as this may indicate worn or broken suspension bushes or damaged coil springs. Inspect the brake system thoroughly, checking for uneven wear on brake discs or pads, which could signal binding calipers or corroded brake pipes—both of which were major issues in previous MOTs. Additionally, verify that the rear boot lid and front headlamp aim are functioning correctly, as these were also major failures in 2024. On the exterior, look for signs of rust or structural damage around the sub-frame and underbody, as the 2023 MOT highlighted significant mounting damage that could compromise the vehicle’s stability and safety. For the tyre condition, despite the advisories of minor cracking or perishing noted in 2022, the buyer should perform a thorough visual inspection of the sidewall wear and integrity, particularly given the vehicle’s age. Tyres older than six years without recent tread renewal should be replaced, as the rubber can become brittle and prone to failure. Check for any signs of uneven wear patterns, which may indicate alignment or suspension issues that have not yet been addressed. The battery should also be tested for health, as prolonged idleness can lead to sulphation or weak terminals, especially in a vehicle this age. Finally, since the vehicle has not undergone a full service in recent years, consider checking the service book for any missing or outdated fluid servicing, such as brake fluid, coolant, and transmission fluid, which degrade over time regardless of mileage. If the vehicle has been stored for extended periods, a thorough fluid flush and inspection of seals and hoses would be prudent to prevent contamination or leakage. The buyer should also request a detailed service history, particularly for the suspension and braking components, to gauge the extent of past maintenance efforts.
