2006 Mazda 5 2.0L Diesel · FH55 CSO

The vehicle passed its most recent MOT on 24 May 2025, but the overall maintenance trend indicates a gradual decline in structural and component integrity. While the car consistently passes, there is a persistent and expanding list of advisories related to corrosion and wear. The recurrence of fuel pipe and sub-frame corrosion suggests that these issues are being monitored rather than proactively remediated, which is typical for a vehicle of this vintage but requires careful scrutiny to ensure the vehicle remains safe and viable. With a recorded mileage of 153,605 miles over approximately twenty years, the vehicle has averaged around 7,680 miles per year. This represents a typical usage profile for a family vehicle of this era, suggesting it has not suffered from extreme high-mileage wear nor the degradation associated with prolonged standing. However, at this mileage, the drivetrain and chassis components have undergone significant fatigue, making the current state of the suspension and structural mounting points critical to the vehicle's long-term roadworthiness. Prospective buyers must pay close attention to the chassis and fuel system. The recurring advisories for corroded fuel pipes and the rear sub-frame are concerning, as fuel line degradation can lead to leaks and safety hazards, while sub-frame corrosion can eventually compromise structural integrity. During a physical inspection, use a torch to examine the underside, specifically the offside rear area. On a test drive, listen for knocks or clunks from the rear end, which would indicate that the previously noted worn suspension arm bushes and corroded coil springs have progressed to a state of failure. The brake history shows a pattern of deferred maintenance, with rear discs and pads appearing as advisories for several years before the front discs eventually required replacement in 2023. You should check for brake shudder during deceleration and ensure the pedal feel is firm. Verify whether the rear discs have been replaced since the 2023 advisories. Given the age and mileage, it is essential to review the service history for evidence of timing belt or chain maintenance and fluid changes, as calendar-based degradation of oils and coolants can occur regardless of the moderate annual mileage.
