1998 Peugeot 806 1.9L Diesel · S70 DAJ

The most recent MOT on 29 January 2024 at 139,162 miles failed because the offside rear passenger door did not latch securely and an oil leak was recorded (8.4.1 (a)(i)). The vehicle’s maintenance trend is clearly worsening; after a relatively stable period through the early 2010s, failures have clustered in the last two years, with brake binding, steering play, exhaust leaks and multiple electrical faults emerging repeatedly. Mileage accumulation has been uneven for a 1998 model. Over roughly 28 years the car averages about 5,000 miles per year, which is low for its age. The log shows a slow rise up to 2020, then a jump of 11,817 miles between March 2021 and April 2022, followed by a further 20,887 miles to 128,786 miles by April 2022, and finally 10,376 miles to the current 139,162 miles in early 2024. This pattern indicates long periods of light use punctuated by bursts of higher utilisation, suggesting that wear may be concentrated in components that were idle for extended intervals. A buyer should inspect the door latch mechanism, the source of the oil leak and the associated seals. The brake system demands close scrutiny: front brake binding, rear brake imbalance, thin pads, deteriorated hoses, and a parking‑brake efficiency fault all point to potential uneven wear and possible corrosion. Steering components are another priority; excessive free play in the rack, play at the track‑rod ends and a heavier power‑steering feel indicate wear in the rack inner joint and suspension arm ball joints. The exhaust shows both major and minor leaks, so a thorough check for rust holes and secure mounting is essential. Electrical faults are also evident, with side‑repeater lamps, wiring connectors and the battery terminal security requiring verification. Addressing these issues will be necessary to restore roadworthiness and prevent further deterioration.
