1997 Mazda Bongo 2.5L Diesel · P362 AHO

The most recent MOT, carried out on 3 June 2026, resulted in a Pass but with four advisories – a minor leak at the exhaust‑gas joining flange to the centre box and corrosion‑related holes in the near‑side front inner sill, off‑side centre inner sill, off‑side outer sill and near‑side rear outer sill. Compared with the preceding two‑year period, the vehicle has moved from outright failures (stop‑lamp failure, major exhaust leak and severe anti‑roll‑bar bush wear) to a clean pass, indicating that the most critical safety items have been rectified. However, the persistence of multiple corrosion advisories and the recurring tyre perishing notes suggest that the overall maintenance trend is stabilising rather than improving, and that ageing under‑body components remain a concern. At 195,258 miles recorded in September 2026, the Bongo averages just under 10,000 miles per annum over its twenty‑year life. This usage rate is typical for a light commercial van of this vintage and does not point to any periods of excessive short‑term mileage accumulation. The mileage figure, however, combined with the age of the vehicle, means that many wear items – tyres, suspension bushings, brake discs and the exhaust system – are likely to be approaching the end of their service lives, regardless of the relatively moderate annual distance. Prospective buyers should give particular attention to the corrosion noted on the front and rear sills. Inspect the affected panels for any progression of rust that may have penetrated the metal thickness, and check for any signs of water ingress into the cabin or interior trim. A compromised sill can affect structural rigidity and may lead to further corrosion of adjoining chassis members, so any repair should involve proper surface preparation, rust‑inhibiting primer and quality filler or panel replacement. The minor exhaust leak at the joining flange should be examined for cracked or warped metal, loose clamps or deteriorated gaskets; symptoms to listen for include a faint hissing or ticking at idle and a noticeable increase in exhaust noise, while a leak can also raise emissions levels and contribute to under‑hood heat. Verify that all stop‑lamp units now illuminate correctly, as the vehicle previously failed this test on two occasions; a faulty bulb, wiring harness corrosion or a blown fuse can be easily diagnosed with a simple visual check and a functional test of the rear lights. Given the consistent advisories about tyre cracking, perishing and edge wear on all four wheels, a full tyre inspection is essential – look for dry rot, sidewall cracks, uneven tread wear and any bulges that could indicate internal damage. Replacing the tyre set is likely to be an imminent expense. While you are on the vehicle, examine the anti‑roll‑bar bushings and other suspension links for any play or clunking when the wheels are rocked, as previous major wear on these components can re‑appear if not fully refurbished. Check the brake discs for surface corrosion or scoring, and ensure the calipers move freely without binding, especially after long periods of standing. Finally, assess the condition of the 12 V battery (terminal corrosion, charge hold), verify that engine oil, coolant and brake fluid have been changed within the recommended intervals, and confirm that the service book contains regular entries – these time‑based items are as critical as mileage‑driven wear on a vehicle of this age.
