2017 Land Rover Discovery 2.0L Diesel · WH17 DFK

The 2017 Land Rover Discovery most recently passed its MOT on 22 July 2026, but the test history over the preceding two years indicates a worsening rather than stable maintenance picture. A fail on 21 July 2026 was triggered by a major defect for an excessively corroded nearside rear brake pipe, just one day before the subsequent pass, which suggests an urgent repair was completed to clear the advisory that had been flagged repeatedly since 2022. The lower suspension arm pin or bush advisories on both front sides have also recurred at every test since at least 2023, meaning these components have not been replaced and continue to deteriorate. Combined with a previous fail for an ineffective windscreen wiper and a deeply cut rear tyre, the trend points to a vehicle that is being kept on the road reactively rather than through proactive component replacement, and a prospective buyer should treat the latest pass as the baseline rather than evidence of trouble-free condition. The recorded mileage of 35,811 miles over approximately nine years equates to an average annual usage of just under 4,000 miles, which is notably low for a vehicle of this type and age. Such modest annual mileage typically reflects a mix of light use and extended periods of standing, both of which carry their own mechanical consequences. While wear-related failures on engines, transmissions and major drivetrain components are likely to be less advanced than on a higher-mileage equivalent, prolonged standing tends to encourage brake disc corrosion, caliper seizure, moisture accumulation in brake fluid, and accelerated ageing of the 12V battery, tyres and rubber components. A buyer should therefore not assume that low mileage automatically equates to a well-preserved example and should focus inspection on corrosion and age-related degradation rather than high-mileage wear items. The recurring front lower suspension arm bush advisories warrant close physical inspection before purchase. Worn bushes of this nature typically produce clonking or knocking noises over speed humps, uneven tyre wear particularly on the inner or outer edges, vague steering response, and a tendency for the front end to shift slightly under hard braking. As these advisories have now appeared over four consecutive tests, the bushes are clearly worn beyond first-onset stage and replacement of the affected arms, or at minimum the bush inserts, should be budgeted for. Similarly, the nearside rear brake pipe has been flagged with corrosion advisories since 2022 and finally failed outright in 2026, which strongly suggests the brake line was either repaired or replaced just before the subsequent pass. A buyer should confirm the nature of the work, inspect the surrounding underbody for any further corrosion on fuel lines, subframe mounting points and suspension components, and verify that the brake fluid has been fully bled and renewed rather than simply topped up. Given the low annual mileage and the vehicle's age, several non-MOT items deserve particular attention during a physical inspection and pre-purchase evaluation. Tyres fitted to a low-mileage vehicle are frequently the originals or early replacements and may exhibit sidewall perishing, cracking between the tread blocks, or hardened rubber compound that compromises grip despite apparently adequate tread depth. The brake discs and calipers should be checked for surface corrosion pitting, binding pistons and seized slider mechanisms, especially on the rear axle which has seen prolonged low-speed use. The 12V battery is almost certainly due for replacement on age grounds alone and should be load tested. Coolant, brake fluid and differential or transfer case oils degrade on a calendar basis rather than purely through use, so service history should be examined for evidence of time-based fluid changes, and the underside of the vehicle should be examined on a ramp for any signs of oil or coolant weeping from ageing seals and gaskets. Finally, the service book should be scrutinised to confirm regular stamping, given that low-mileage examples are often serviced infrequently and the omission of timing belt or chain inspections, transfer case oil changes or air conditioning services can prove expensive to rectify retrospectively.
