2017 Land Rover Discovery 3.0L Diesel · V6 XAJ

Consistent roadworthiness has been the defining characteristic of this Land Rover Discovery, which has maintained a clean record of annual passes since its initial testing cycle, including the most recent inspection on 29 January 2026. Aside from minor, transient advisories regarding tyre wear and interior equipment, the vehicle has avoided significant mechanical failures or structural concerns in the official testing data. This trajectory suggests a stable history of compliance, though the absence of reported defects does not preclude the presence of hidden wear or latent mechanical issues that fall outside the scope of a standard MOT assessment. Accumulating 78,471 miles over a nine-year period results in an average of approximately 8,719 miles per annum, a usage rate that remains well within the expected range for a vehicle of this classification. This steady accumulation indicates that the vehicle has been in regular operation rather than subjected to long periods of inactivity, which often leads to the degradation of seals, bushes, and electrical systems. While the mileage is typical, the complexity of the Discovery platform means that components such as air suspension compressors, electronic control modules, and drivetrain linkages will have reached a stage where accelerated wear is statistically probable regardless of the consistent pass history. Given the history of tyre edge wear noted in 2023, a thorough inspection of the suspension geometry and wheel alignment is essential during your evaluation. Uneven tyre wear on these vehicles is frequently linked to play in the suspension control arm bushes or ball joints, which can be difficult to detect on a static lift. During your test drive, listen specifically for any knocking or clunking noises when traversing uneven surfaces or speed bumps, as these are primary indicators of worn bushings or failing anti-roll bar links. Furthermore, ensure the vehicle maintains a level stance when parked and that the air suspension system cycles through its height settings without audible labouring from the compressor. The presence of a child seat during the 2024 inspection prevented a full assessment of the rear seatbelt mechanism, so you should manually extend and retract all rear seatbelts to ensure the locking retractors function correctly and the webbing is free from fraying or contamination. As this vehicle approaches higher mileage, pay close attention to the transmission shift quality and listen for any whining or grinding from the differentials during low-speed manoeuvres. While the MOT history shows no evidence of fluid leaks, you should inspect the underside for any signs of oil misting around the engine sump or gearbox housing, as early detection of these issues is critical for long-term reliability in this model.
