2006 Nissan Navara 2.5L Diesel · AV06 KFX

Chronic structural corrosion and persistent fluid leaks define the mechanical history of this vehicle, which passed its latest MOT on 2 April 2026 despite a significant list of recurring advisories. The record reveals a pattern of chassis degradation, including a major failure in 2023 for excessive corrosion on the offside rear inner structure and a dangerous failure in 2024 due to a leaking nearside front brake pipe. While it currently holds a valid certificate, the repeated mentions of corroded sills, coil springs, and general chassis corrosion indicate a vehicle with ongoing oxidation issues across its structural framework. With 127,717 recorded miles, the vehicle has averaged approximately 6,386 miles per year over its twenty-year lifespan. This usage rate is typical for its age, suggesting consistent moderate use rather than extreme heavy-duty application or prolonged periods of standing. Mechanically, this mileage level often coincides with the wear of drivetrain seals and the degradation of suspension components, which is reflected in the documented oil leaks and steering roughness. A physical inspection must prioritise the chassis and sills, specifically the nearside rear inner sill and the offside front coil spring, both of which are currently flagged as corroded. Given the history of brake pipe failure and corrosion, the entire braking system should be examined for signs of pitting or lines that have been covered in grease to mask oxidation. During a test drive, pay close attention to the steering feel; the recorded roughness when rotating the wheel may manifest as notchiness, hesitation, or uneven resistance in the steering rack and linkages. The persistent oil leaks from the transfer box, gearbox, and differential require close scrutiny. Check the underside for active dripping or heavy oil saturation around these central components. Listen for unusual whining or humming noises from the drivetrain under load, which can occur when fluid levels are compromised by chronic leaks. The structural integrity of the chassis should be verified by a professional, as the vehicle has a documented history of failing for excessive corrosion in critical mounting areas.
