1997 Peugeot 806 1.9L Diesel · R152 DDA

The February 2023 test at 150,375 miles represents the vehicle’s most recent MOT and it passed only after a series of advisories. The tester flagged an inoperative offside rear registration plate lamp, slightly deteriorated front brake hoses, corroded front, rear and central brake pipes, front tyres worn to the legal limit, an oil leak, and a severely deteriorated near‑side front drive‑shaft constant‑velocity boot. Those items indicate that the car remains borderline roadworthy; the pattern of similar faults in earlier failures shows a stable‑to‑worsening trend rather than improvement. Mileage accumulation has been modest, roughly 5,200 miles per year over 29 years, which is low for the vehicle’s age and points to light use or extended periods of storage. The MOT record shows a gap of about three and a half years since the February 2023 test, a notable interval for a 1997 model that requires annual testing. Between January 2022 (148,762 miles) and February 2023 the odometer rose only 2,613 miles, suggesting the car has not been driven intensively, yet the documented wear on tyres, brake components and the CV boot contradicts a purely low‑stress usage profile. A prospective buyer should focus inspection on the recurring problem areas. The brake system demands close scrutiny: check all brake pipes for corrosion and grease contamination, test for hose deterioration, verify rear‑brake balance, and assess pedal feel. The near‑side front constant‑velocity boot should be examined for cracks that could lead to joint failure. Tyre condition is critical—measure tread depth, inspect sidewalls for tears, and assess edge wear. The registration plate lamp must be functional, and any oil seepage around the sump or connections should be investigated. Finally, inspect the front suspension lower arm bushes and ball‑joint dust covers for wear or ingress of dirt, and examine the rear body panels for rust that could affect structural integrity. Addressing these items before purchase will reveal the true mechanical condition of the 806.
