2001 Mercedes-Benz 240 2.6L Diesel · RG51 FCF

The most recent MOT test on the 2001 Mercedes-Benz 240 occurred on 2026-09-01, which has not yet been recorded in the provided history—suggesting the last inspection was conducted in September 2025. However, the preceding MOT history reveals a pattern of recurring issues that have fluctuated between minor failures and advisories, with a notable failure in 2018 due to critical rear brake pad wear and lighting faults. While there were periods of clean MOT results in 2018 and 2021, the vehicle’s history is not entirely stable, particularly concerning the front suspension and braking systems, where multiple advisories and major defects—such as excessively worn lower suspension arms and wheel bearings—have been documented. The advisories on anti-roll bar bushes and ball joints in 2020 and 2022 indicate ongoing wear in these components, which, if left unaddressed, could lead to further suspension instability or alignment issues. The vehicle’s performance in previous MOTs has been inconsistent, with some tests passing but others revealing significant mechanical degradation, particularly in the suspension and braking subsystems. The recorded mileage of 178,770 miles for a vehicle aged approximately 25 years represents a moderate annual usage rate of around 7,151 miles per year, which is typical for its age and class. This level of mileage does not necessarily indicate excessive wear if the vehicle has been maintained under regular operational conditions, but it does suggest significant exposure to road stresses over time. The absence of recent high-mileage spikes or prolonged periods of inactivity does not immediately raise red flags, but the combination of high mileage with repeated MOT failures—especially in critical areas like the front suspension and brakes—implies that the vehicle has likely undergone considerable wear and tear. Without service records confirming routine maintenance, the wear progression on components like suspension bushes, wheel bearings, and brake pads could be accelerating, warranting closer inspection to avoid potential failures that could compromise roadworthiness or safety. Given the vehicle’s history of MOT failures and recurring advisories, the prospective buyer should prioritise a thorough mechanical inspection to address the following key areas. Front suspension : The advisories and major failures on the lower suspension arms and anti-roll bar bushes suggest that these components are worn beyond their serviceable limits. On a test drive, listen for excessive clunking or rattling when the vehicle is driven over bumps or at speed, which may indicate loose or broken suspension linkages. Inspect the front suspension for uneven ride height, binding steering, or excessive play in the wheelbase. If the suspension arms or bushes are severely worn, replacement may be necessary to prevent further misalignment or alignment issues. Wheel bearings : The repeated advisories on wheel bearing play indicate that these components are nearing end-of-life. Listen for grinding or whining noises when the vehicle is driven at speed, particularly when turning sharply, as this is a classic symptom of failing wheel bearings. Inspect the wheel hubs for excessive heat or play, and consider replacing the bearings before they fail catastrophically, which could lead to wheel detachment. Braking system : The 2018 MOT failure highlighting rear brake pads below the legal minimum thickness underscores the urgency of checking brake pad and rotor condition. Inspect the rear brake pads for thickness and condition, and listen for grinding or squeaking when braking, which may signal worn pads or warped rotors. For the buyer, given the vehicle’s age and mileage, a practical inspection should also include checks for tyre condition and tread depth , as high-mileage tyres are more susceptible to dry rot or sidewall cracking, which can compromise structural integrity. Inspect the tyres for signs of perishing, such as cracking or delamination in the sidewall, and ensure the tread depth meets legal requirements (minimum 1.6mm). Check for uneven wear patterns, which may indicate alignment or suspension issues that were previously noted in the MOT history. Battery health : Given the vehicle’s age, the 12V battery should be tested for voltage output and overall condition, particularly if the vehicle has been stored for extended periods. A weak battery can lead to poor starting performance or electrical gremlins, so consider replacing it if it shows signs of corrosion or reduced capacity. Fluid servicing : Since the vehicle has accumulated significant mileage, it is advisable to check the condition of fluids such as the coolant , brake fluid , and transmission fluid , as these can degrade over time, even without significant mileage. Coolant should be free of contaminants and at the correct level, brake fluid should be clear and free of moisture, and transmission fluid should be checked for colour and viscosity. If fluids appear degraded, they should be replaced according to manufacturer recommendations. Finally, verify that the service book is up to date, as this will provide a record of scheduled maintenance, such as oil changes, timing belt replacements, and suspension servicing, which are critical for long-term reliability. If service records are incomplete, arrange for a comprehensive maintenance schedule to address any outstanding work.
