2004 Nissan Navara 2.5L Diesel · CX54 AFA

Corrosion and fluid management issues represent the primary mechanical risks for this vehicle, with the most recent MOT passed on 03 October 2025 showing a trend of increasing structural and drivetrain advisories. While the vehicle has avoided major failures in its most recent tests, the cumulative record shows recurring concerns regarding brake pipe corrosion, seat belt anchorage area degradation, and more recently, widespread integral body structure corrosion. The presence of an advisory for an oil leak and a minor exhaust gas leak at the flexi-joint, alongside play in the central front prop shaft bearing, indicates a vehicle where multiple systems are currently exhibiting signs of wear and degradation. The recorded mileage of 251,621 miles over approximately 22 years equates to an average annual accumulation of roughly 11,437 miles. This usage pattern is consistent with typical long-term utility use for a vehicle of this age and type. Mechanically, this level of mileage suggests that high-wear components such as suspension bushes, drivetrain bearings, and exhaust systems have been subjected to significant cycles of operation. The consistency in annual mileage suggests a steady usage profile rather than long periods of stationary storage, which can sometimes lead to different types of component seizure or degradation. A physical inspection and test drive should prioritise the structural integrity and drivetrain smoothness. Given the advisory regarding integral body structure corrosion, a thorough examination of the chassis and sills is necessary to ensure the corrosion is not progressing beyond the reported levels. The advisory for play in the central front prop shaft bearing warrants a test drive to check for vibrations or humming noises coming from beneath the centre of the vehicle, particularly under acceleration or at cruising speeds. Additionally, the reported exhaust leak at the flexi-joint should be monitored for changes in exhaust note or smell within the cabin, which could indicate the leak is expanding. Braking and fluid systems require close scrutiny due to the history of corroded brake pipes and recent oil leak advisories. You should check for any signs of weeping from engine or gearbox seals and inspect the condition of the brake lines, specifically noting the nearside rear pipe previously flagged for corrosion. During the test drive, pay close attention to the brake pedal feel; any sponginess or unevenness could indicate issues with the integrity of the brake pipes or calipers. The recent inoperative nearside registration plate lamp is a minor electrical fault that should be rectified to ensure full compliance with lighting regulations.
