1999 Mazda Bongo 2.5L Diesel · T723 DET

The most recent MOT on 30 March 2026 was a pass, albeit with two advisories – a minor oil leak that is not yet excessive and a defective spare tyre. Over the past three years the vehicle has shown a mixed record, alternating between passes and failures that were rectified promptly, indicating that the owner has been responsive to remedial work. The pattern suggests a generally stable maintenance regime, though the recurrence of lighting faults and the anti‑roll bar dust‑cover issue points to occasional lapses that should be monitored. At 178,161 miles and 27 years old the average annual mileage works out at roughly 6,600 mi, which sits comfortably within normal UK usage for a vehicle of this vintage. The figures do not reveal any periods of extreme mileage accumulation that would accelerate wear on major drivetrain components, but the relatively modest yearly distance also hints at possible long spells of inactivity. Prolonged storage can promote rubber and polymer degradation, corrosion of brake discs and calipers, and battery sulphation, all of which merit close inspection. When you examine the vehicle, give particular attention to the front anti‑roll bar linkage and its dust cover; a compromised cover can allow grit to infiltrate the joint, leading to premature wear and a potential clunk or loose feel from the front suspension under cornering. Verify that the fog lamp and rear stop lamp are operational, as lighting failures have featured in recent MOTs and may indicate wiring or connector corrosion that could also affect other circuits. Inspect the oil sump and valve cover gaskets for signs of seepage beyond the advisory level – any steady drip onto the engine bay floor or oil spots on the under‑tray should be addressed before the leak worsens. The spare tyre should be checked for tread depth, sidewall integrity and correct inflation; a defective spare reduces safety in the event of a puncture. Given the vehicle’s age, conduct a thorough visual and tactile assessment of the tyres for sidewall cracking, dry rot or uneven wear that could betray mis‑alignment or worn suspension bushes. Examine the suspension components – especially the rubber bushings, ball joints and coil springs – for cracks, hardening or excessive play, which would manifest as knocks or a vague shudder when traversing bumps. Test the brakes for any pulsation, noise or uneven pad wear, and look for surface rust on the discs that could cause scoring. Check the 12‑volt battery voltage and terminal condition, as a 27‑year‑old unit may have diminished cranking power. Finally, confirm that the service book shows regular oil, filter and coolant changes at appropriate intervals; time‑based fluid degradation can occur even on low‑mileage vehicles, so fresh oil, brake fluid and coolant are advisable before committing to purchase.
