2012 Land Rover Discovery 3.0L Diesel · KE12 ACZ

A recurring thread of suspension, brake and underbody component wear runs through the MOT history of this 2012 Land Rover Discovery, with multiple advisories pointing to ageing consumables on both the front and rear axles. The most recent test on 2023-01-26 recorded a pass with no defects, but the trend across the five previous years shows a vehicle accumulating typical wear items rather than presenting a spotless record. A failed retest on 2022-04-08 caught two headlamp aim defects and an inoperative number plate lamp, all classed as items easily rectified but symptomatic of a vehicle requiring ongoing electrical and lighting attention. The 2020 failures are more serious, with both front tyres recorded as Dangerous for exposed ply or cords alongside a windscreen washer major, indicating that tyre monitoring had lapsed at that point. Across the five-year window there are advisories for worn front brake discs on two consecutive tests, front suspension arm pin or bush wear on both sides, corroded brake ferrules and a corroded central rear upper brake pipe, plus a central front oil leak noted as not excessive. With 122,041 miles recorded over approximately fourteen years, the vehicle has averaged around 8,700 miles per year, which sits broadly in line with typical usage for a vehicle of this age and class. The MOT testing pattern is consistent with regular use, with annual or near-annual tests from 2019 onwards and no extended gaps that would suggest long periods of standing. For a Land Rover Discovery of this vintage and mileage, this rate of accumulation means the major mechanical components such as the engine, gearbox, transfer box and drivetrain have been worked, and consumable items including brakes, tyres, suspension bushes and exhaust system components are likely to be approaching or past their second or third replacement cycle. The mileage profile does not raise immediate concern, but it does underline the importance of inspecting wear items closely rather than assuming any major component is in original condition. The advisories for front suspension arm pin or bush wear on both sides in 2022, and on the offside rear bush in 2020, are particularly relevant for a Discovery of this age, as the front lower suspension arms, radius arms and anti-roll bar bushes are known to deteriorate with mileage and can permit noticeable movement before showing as an MOT failure. On a test drive, listen for clonks or knocking from the front end over speed humps, rough surfaces and during full-lock low-speed manoeuvres, and check for vague or wandering steering on the motorway. The front brake disc advisories in 2020 and 2021, combined with the 2019 advisory for thinning front brake pads, suggest the discs and pads have been replaced or refaced at least once, so check for brake judder under firm pedal application, binding calipers after driving, and a spongy or excessively long pedal travel. The brake line and hose advisories warrant close physical inspection underneath the vehicle. The 2022 entry for slight corrosion to the front brake hose ferrules on both sides, and the corroded central rear upper brake pipe covered in grease, are typical Discovery issues given the underbody exposure to road salt and moisture. Examine all visible brake pipes, particularly along the chassis rails, rear axle lines and behind the front wheels, for any blistering, flaking or weeping of brake fluid, and pump the pedal several times with the engine running to confirm a firm, consistent feel. The central front oil leak noted in 2022, although not excessive, should be monitored for drips on the driveway and investigated for source, as Land Rover V6 and V8 engines of this era commonly seep from sump gaskets, timing covers and front crankshaft seals. Finally, the 2020 Dangerous tyre failures on both front tyres highlight the need to confirm the current tyres have substantial tread across the full width, with no uneven shoulder wear that could point to suspension geometry or tracking issues.
