1998 Mazda Bongo 2.5L Diesel · R274 DKY

The most recent DVSA examination on 16 October 2025 resulted in a pass, although this followed a fail recorded only seven days earlier on 9 October 2025, where the vehicle was presented with two major front position lamp failures and split constant velocity boots on both front outer drive shaft joints. The owner clearly addressed the failed items to achieve a pass, but three advisories were carried forward into the pass certificate, including light oil misting from the offside front shock absorber, multiple cuts on the offside rear tyre, and corrosion noted on the offside inner integral body structure, specifically the sill. The overall maintenance trend raises some concern. The previous 2024 tests were notably clean, with no advisories recorded across two passes in May and October, yet the 2024 March test contained a dangerous brake pad defect and a major suspension arm bush wear item. This suggests that while the vehicle has not been neglected, it is now showing classic age-related wear on suspension and braking components, and the sudden cluster of advisories on the most recent pass indicates that further deterioration should be anticipated over the coming months rather than the vehicle stabilising into a trouble-free period. With 192,370 miles recorded over approximately 28 years, this Mazda Bongo has covered an annual average of around 6,870 miles, which is broadly typical for a vehicle of this vintage, whether used for light commercial duties or family transport. The mileage progression across the recorded MOT history is reasonably consistent, suggesting regular use rather than long periods of standing, which is generally favourable for mechanical condition. That said, at this mileage the engine, transmission and drivetrain components are well into the second half of their service life, and the recorded history shows wear items on suspension bushes, shock absorbers, CV joints and brake components, all of which are consistent with a working high-mileage vehicle. The relatively even annual mileage should mean that consumables have been replaced at sensible intervals, but buyers should expect that further replacements of wear items are imminent given the advisories already logged. The advisories and defects recorded across the recent tests warrant careful physical inspection before purchase. The offside front shock absorber has light oil misting, which on a test drive typically presents as reduced damping over uneven surfaces, a slight nose-dive under heavy braking, or a clonking sound from the front corner over speed humps and potholes. While this is presently an advisory, dampers usually progress from misting to a more visible leak within a few thousand miles, and replacement of both front units is advisable to maintain balanced handling. The cuts on the offside rear tyre should be examined closely for any signs of bulging or cord exposure, as the advisory confirms they have not yet reached the ply, but the tyre should be replaced regardless given its age and the high overall mileage. The sill corrosion noted as not significantly reducing structural rigidity should be inspected from underneath with a torch to confirm there is no hidden perforation, particularly around jacking points and the inner wheel arch lip, as Mazda Bongo sill rot is a well-known weakness in older examples. Beyond the items recorded by DVSA, a prospective buyer should carry out several physical checks appropriate to a 28-year-old commercial vehicle. The offside front lower suspension arm rear bush was flagged as excessively worn in early 2024, and although presumably replaced, the corresponding nearside bush may now be approaching the end of its service life, so a thorough inspection on a ramp is worthwhile. Brake discs showing pitting and scoring on both rear sides have been advised, which can lead to brake shudder under heavy application and may necessitate disc replacement before the next MOT. The CV boots, recently noted as split, will have allowed some contamination of the joints, so listen for clicking on full lock turns during the test drive, which would indicate joint wear requiring replacement. Given the age, also examine all tyres for sidewall cracking and perishing even where tread depth is adequate, test the 12 volt battery under load for cranking strength, check the coolant and brake fluid for time-based degradation regardless of appearance, and verify that the cambelt or timing chain service interval has been documented, as this is a critical replacement on a high-mileage petrol or diesel engine of this era. Finally, inspect the underside comprehensively for any fluid leaks, examine the rear load area floor for corrosion, and confirm the service book history to ensure major mechanical servicing has been carried out at appropriate intervals.
