2018 Renault Koleos 2.0L Diesel · YH68 DOA

A recurring pattern of initial test failures and concentrated front-end suspension and tyre wear defines the mechanical history of this Renault Koleos, culminating in its most recent pass on April 17, 2026, after rectification of a major dipped-beam headlamp defect and an excessively worn offside front suspension arm ball joint. The overall trajectory reveals persistent wear on front-end components, with multiple test cycles featuring both initial refusals and subsequent passes. Advisories noted during the latest inspection include an active stop-start fault on the dashboard, an offside front outer tyre wearing on the edge, and an engine oil leak noted as not excessive, pointing to ongoing mechanical attention required for this vehicle. Accumulating 79,840 miles over its eight-year lifespan yields an average of approximately 9,980 miles annually, representing a typical UK driving profile without prolonged periods of inactivity or extreme mileage spikes. This steady accumulation suggests standard wear and tear across major assemblies rather than the accelerated degradation associated with heavy commercial use or the battery and fuel system complications typically brought on by extended storage. Testing intervals have remained regular through August departures and spring evaluations, ensuring that faults are captured on an annual basis. A rigorous inspection during a static check and test drive must focus on the components highlighted in the MOT records. Prospective buyers should listen closely for knocks, clunks, or vagueness from the front suspension over speed bumps and rough road surfaces, checking specifically for play in the recently replaced offside suspension arm and evaluating the nearside front suspension arm bush which was previously flagged with wear. The braking system requires careful scrutiny of the front discs and pads, which have a documented history of thinning, pitting, and scoring, to ensure adequate friction material remains and that the brakes operate without judder or pulling. Furthermore, the engine bay should be inspected for the source of the recorded oil leak to determine whether it originates from a rocker cover, turbo feed, or sump seal, while the electrical systems must be thoroughly tested to diagnose the dashboard stop-start fault and verify the operation of all external lighting. The front tyres should be checked for matching tread depth and uneven shoulder wear patterns that could indicate underlying wheel alignment issues resulting from past suspension wear.
