2017 Land Rover Discovery 3.0L Diesel · T1 DTC

The most recent MOT test for this 2017 Land Rover Discovery was conducted on 2025-09-19 and resulted in a pass, though it included a single advisory regarding the rear registration plate deterioration, which is not critical to roadworthiness but may affect readability in adverse conditions. The overall maintenance trend over the past five years is mixed but not alarming. While there have been multiple MOT failures—particularly in 2022 and 2025—each failure has been addressed with advisories or minor defects that do not compromise safety, such as worn suspension bushes or minor brake wear. The most significant failure, the offside rear hydraulic brake calliper leak and compromised braking performance in 2025, was likely rectified, as subsequent tests show no recurrence of that specific issue. The recurring advisories on brake pad wear and suspension bush condition suggest routine but necessary attention to consumables and wear items, which is expected in a high-mileage vehicle. The recorded mileage of 93,687 miles for a nine-year-old Discovery represents a reasonable annual usage rate of approximately 10,410 miles per year, which is typical for this model’s age and usage profile. Lower mileage could indicate periods of inactivity or lighter use, potentially leading to more pronounced issues such as fluid degradation from standing or standing corrosion on components like brake discs or suspension linkages. Conversely, higher-than-average mileage would accelerate wear on consumables like brake pads, seals, and suspension bushes, as seen in the repeated advisories. The absence of significant gaps in mileage suggests consistent driving, which may mitigate some age-related wear but does not eliminate the need for proactive checks, especially on high-stress components like the drivetrain and braking system. For a prospective buyer, this vehicle warrants a thorough mechanical inspection beyond the MOT record. Focus on the rear brake system, as the 2025 failure highlighted a leaking calliper and compromised braking performance, which could indicate a failing hydraulic line or worn seals. During a test drive, listen for uneven braking response, particularly on the offside rear, and check for brake dust accumulation or a spongy pedal feel, which may signal fluid contamination or a failing master cylinder. The worn suspension bushes from the MOT history should be inspected for excessive play or clunking noises when driving over bumps, which could lead to misalignment or uneven tyre wear. Additionally, verify the brake discs for pitting, scoring, or binding, as these conditions can reduce stopping efficiency and require replacement. Beyond the mechanical checks, address the age-related wear and potential fluid degradation. Given the vehicle’s age and mileage, inspect the tyres for sidewall cracking or perishing, which can compromise structural integrity and safety, especially in cold or wet conditions. Check the 12V battery for signs of weakness, such as slow cranking or corrosion on terminals, as standing vehicles can drain batteries over time. Fluid servicing should be prioritised, with particular attention to brake fluid, which can absorb moisture and degrade over time, even without use. Lastly, verify the service history for scheduled maintenance, such as oil changes, timing belt replacement, and suspension component servicing, as these are critical for long-term reliability. If the vehicle has been stored for extended periods, inspect for corrosion on standing components like the exhaust system, fuel lines, or underbody areas, as moisture can accelerate rust formation.
