2010 Land Rover Range Rover Sport 3.0L Diesel · V6 ASN

A pattern of brake and underbody corrosion dominates the mechanical story of this Range Rover Sport, with multiple MOT failures and advisories over the past four years pointing to a vehicle that is showing its age in the metalwork and hydraulic systems. The most recent test on 16 April 2026 was a clean pass with no defects recorded, but this must be read against the broader history. In early 2024 the vehicle failed on a seriously imbalanced rear axle and a binding nearside rear service brake, with advisories noting overheating on the same corner and heavy corrosion affecting four steel brake pipes running the full length of the car. A failure in January 2023 was directly linked to excessively corroded offside and nearside rear brake pipes severe enough to prevent a brake performance test being carried out, and the 2022 pass had already flagged all rear brake pipes as corroded though coated in grease. Separately, a March 2025 failure recorded a leaking ACE pipe on the offside front suspension, an active anti-roll system component which is known to be costly on this platform. Across the 2023 tests there were also general advisories about various items corroded under the vehicle, reinforcing the corrosion theme rather than contradicting it. With 87,460 miles accumulated over sixteen years, annual mileage works out at roughly 5,466 miles per year, which is low for a vehicle of this type and age. The recorded tests are broadly annual from 2022 onwards, suggesting the vehicle has been in regular but light use rather than laid up for extended periods, and there are no obvious gaps or sudden mileage jumps to indicate inconsistent keeping. Low mileage on a Range Rover Sport of this generation does reduce wear on the drivetrain and major internal components, but it can also accelerate surface corrosion on exposed underbody metal and brake lines because short journeys and damp conditions promote oxidation without the heat cycles that come from sustained driving. The repeated brake pipe corrosion advisories and underbody corrosion notes are consistent with that usage profile, where the vehicle is being used enough to be tested but not always run hard or far enough to fully dry out the chassis. A prospective buyer should treat the brake pipe history as a live issue rather than a resolved one, because corrosion once initiated tends to continue progressing even after replacement sections are fitted. On inspection, ask for evidence of what work was carried out following the 2024 failure and the 2023 brake pipe advisories, including whether the rear pipes were replaced in stainless or standard steel, and check the condition of any visible unions along the chassis rails, particularly the rear sections running to the axle. Look for fresh underseal or paint overspray that might be hiding active corrosion, and feel for a soft or spongy brake pedal on a test drive, which can indicate air ingress from a leaking joint. Because the 2024 test recorded a binding nearside rear caliper with associated overheating, the car should be driven from cold with the windows down so any scraping, dragging, or uneven deceleration can be heard and felt before warmth masks the symptom. The ACE pipe failure on the offside front in March 2025 is the other area demanding specific attention, as the Active Cornering Enhancement system on this model uses hydraulic pressure within the suspension, and a leaking pipe can lead to a heavy or uneven feeling through corners and warning lights on the dashboard. When test driving, listen for any new fluid noise from the front suspension area, watch for the vehicle sitting lower on one side after being parked overnight, and check the reservoir level before and after the drive. The 2023 advisory about general underbody corrosion also warrants a physical inspection on a ramp, focusing on the subframe, outriggers, and suspension mounting points, because surface rust on cosmetic panels is very different from structural corrosion affecting load-bearing members. Finally, given the recorded sidewall damage advisory on the nearside front tyre in 2024, inspect all four tyres carefully for any cuts, bulges, or uneven wear, and confirm the wheels are free of vibration at speed, as the combination of low annual mileage and corrosion history on this Range Rover Sport means a thorough physical survey matters more than the single clean pass in April 2026 would suggest.
