2018 Bentley Bentayga 4.0L Petrol · SK18 KWL

Most recent MOT (12 May 2026) The car passed the test at 41 470 mi, but the examiner noted “off‑side rear shock absorber has light misting of oil” (item 5.3.2 (b)). This is the only defect recorded in the latest MOT. Recurring mechanical pattern A similar oil‑mist warning was logged on 6 Nov 2024 for the same off‑side rear shock absorber. Apart from that, the MOTs in 2025, 2023 and early 2023 were clean. The repeat observation suggests a slow leak or seal wear in that shock, rather than an isolated incident. Trend assessment The defect has not progressed to a failure – the vehicle still passed each test – but the fact that the same shock has been flagged twice over a 1½‑year span indicates a stable, low‑level issue rather than an improving one. If the leak worsens, it could lead to reduced ride quality or premature shock failure, so monitoring is advisable. Mileage versus age At 41 470 mi the 2018 Bentayga averages about 5 200 mi per year, well below the typical ~10‑12 000 mi for a luxury SUV of this age. Low mileage can mean the car has been driven gently, which is favourable for engine and drivetrain wear. However, prolonged periods of inactivity can accelerate rubber and fluid degradation, especially in suspension components, which may be part of the shock‑absorber observation.
