2012 Land Rover Discovery 3.0L Diesel · D3 KNH

The Discovery presents a stable mechanical picture as of its most recent MOT on 2026-03-20, where it passed cleanly at 150,551 miles with zero defects. That clean sheet is significant because it follows a period of recurring faults in 2025, suggesting the previous owner addressed those issues rather than ignoring them. The maintenance trend is therefore improving, at least on paper, though the very recent date of the pass — just three months ago — means the vehicle has had limited time to prove its reliability in everyday use. The mileage accumulation is broadly typical for a 12-year-old Discovery, sitting around 10,754 miles per year. Looking at the intervals, the vehicle covered roughly 5,538 miles between the February 2024 pass at 135,622 miles and the March 2025 failure at 141,158 miles, then a further 9,391 miles to the March 2026 test at 150,551 miles. That second interval is noticeably higher, which may point to heavier use or longer commutes in the past year. No alarming gaps appear in the record, though the mileage progression is consistent enough to suggest regular rather than sporadic use. The 2025 failures reveal a pattern worth investigating in person. A corroded rear brake pipe covered in grease or other material appeared at both the March 2025 failure and the subsequent retest, indicating either a temporary fix or a deeper corrosion issue along the underside. A missing constant velocity boot on the propshaft joint was flagged at the same time, which if left unattended would have led to joint failure and potential drivetrain vibration. Rear brake pads were also wearing thin, consistent with the higher mileage interval that followed. Any prospective buyer should inspect the underside thoroughly, paying close attention to brake line condition around the rear axle area, the propshaft joints and boots for fresh grease or play, and the general state of corrosion protection on the chassis and suspension mounting points. The nearside rear registration plate lamp fault from the March 2026 failure was a minor electrical issue, but it is worth checking the full rear lamp cluster and wiring loom for water ingress, a common Discovery trait. The windscreen chip noted in 2025 should be examined to confirm it has not spread beyond repairable limits. Given the vehicle's age and mileage, suspension bushes, coil spring condition, and the operation of the air suspension compressor if fitted deserve a proper inspection, as these components deteriorate progressively and do not always trigger an MOT advisory until well advanced.
