2006 Mercedes V350 3.2L Gas bi-fuel · FX06 VMP

The vehicle most recently passed its MOT on 29 July 2026, though this followed a same-day failure that included a Major defect for an inoperative nearside front direction indicator and a Minor for an inoperative nearside rear registration plate lamp, both of which were presumably rectified prior to the pass. Two advisories remain outstanding from that test: a nearside rear inner tyre worn close to the legal limit and on its edge, and a noisy front upper top mount on full lock to lock. When reviewing the broader three-year test history, the maintenance trend is best described as broadly stable but with a clear and escalating front suspension and steering concern. In 2025, both front anti-roll bar pin or bush assemblies were noted as worn, alongside slight play in the nearside front suspension arm ball joint and inner play in both steering rack inner joints. By 2024, these same anti-roll bar components had deteriorated to the point of Major failure, indicating progressive wear that has not been definitively resolved. The 2024 test also produced an advisory for a nearside front service brake binding slightly, which reappeared in 2023, and a Major failure for parking brake efficiency below requirements, which warrants verification that the parking brake mechanism is now operating correctly and holding the vehicle on an incline. The recorded mileage of 135,507 miles over a 20-year service life equates to an annual average of approximately 6,775 miles, which is broadly typical for a vehicle of this age and broadly consistent with its MOT mileage progression. There are no anomalous gaps or unusually rapid accumulations in the recorded readings, suggesting steady use rather than prolonged standing or extended motorway mileage in short periods. For a diesel-powered Mercedes-Benz V350 of this vintage and mileage, such steady use is generally favourable for preventing the chronic issues associated with low-mileage vehicles, such as seized brakes, perished hoses, and degraded oils, but it does place commensurate wear upon the major drivetrain, suspension, and turbocharger components typical of high-mileage diesel operation. The combination of age and mileage means that age-related degradation of rubber, plastics, and electrical components is just as relevant as wear on mechanical consumables. Given the recurring advisories on the front anti-roll bar bushes, suspension arm ball joint, and steering rack inner joints, a prospective buyer should prioritise a thorough physical inspection of the front suspension and steering assemblies, ideally with the vehicle raised on a ramp. On a test drive, listen carefully for clonking or knocking noises from the front end over uneven surfaces and speed bumps, pay close attention to any vagueness or looseness in the steering response, particularly around the straight-ahead position, and check for uneven front tyre wear which is a classic symptom of deteriorated anti-roll bar bushes or worn suspension arms. The front upper top mount noise on lock-to-lock should be evaluated for any perceptible juddering through the steering wheel or excessive free play, as worn top mounts can compromise ride control and are relatively inexpensive to replace before they damage the surrounding spring and strut assembly. The nearside front service brake binding advisory from both 2023 and 2024 should be physically checked by ensuring the wheel rotates freely by hand when cold after the caliper has been released, and the vehicle should be road-tested for any pulling to one side under braking or evidence of brake disc overheating such as a hot wheel or a burning smell after use. Beyond the recorded advisories, a twenty-year-old vehicle with this mileage requires careful attention to age-based deterioration. The tyres should be examined closely for sidewall cracking and perishing regardless of tread depth, as rubber compounds degrade significantly with calendar age, and the nearside rear inner tyre advisory indicates that replacement is imminent. Inspect the brake discs on all four corners for lipping and surface corrosion, particularly on a vehicle that may stand for extended periods, and confirm the handbrake holds the vehicle without excessive travel. Verify the service history for regular replacement of brake fluid, coolant, and automatic transmission fluid or dual-clutch gear oil depending on the specific variant, as Mercedes-Benz specification fluids degrade over time. Check the condition of all drive belts including the timing belt service interval if applicable, inspect the exhaust system for the corrosion noted on the centre box, and ensure the 12V battery is holding charge with no warning lights on the instrument cluster. Finally, examine the underside for any fluid leaks from the power steering, engine, or transmission, and consider a pre-purchase inspection by a Mercedes-Benz knowledgeable technician to evaluate the condition of the common rail injection system, turbocharger actuator operation, and the overall structural integrity of this now twenty-year-old MPV.
