2010 Renault Grand Scenic 1.5L Diesel · LL10 DXY

A pattern of chronic rear brake line and hose corrosion, combined with two MOT failures in the last three test cycles, defines the mechanical profile of this 2010 Renault Grand Scenic. The most recent test on 1 December 2025 resulted in a pass, but it followed a failure on 13 November 2025 attributed to a serious nearside front shock absorber fluid leak, an obviously incorrect headlamp aim, and inoperative rear lighting. A further failure was recorded on 1 November 2024 for ineffective wipers, an ABS warning lamp fault, and inoperative rear lighting, while the 17 October 2023 entry lists a failure for an electronic parking brake malfunction. Across these six test events, the rear brake pipes and flexible hoses have appeared as advisories on every relevant test since 2023, with the inner and outer offside rear brake pipes noted in three consecutive cycles as corroded or covered in contaminant. Suspension wear has also surfaced, with advisories for lower arm bushes and ball joint play, and a binding offside rear service brake. The trend over the last two years is one of accumulating defects rather than a stable or improving roadworthiness record. Mileage is recorded at 163,757 miles across approximately 16 years of age, equating to roughly 10,200 miles annually. This rate is broadly typical for a family MPV of this era, though the exact mileage gap between tests cannot be precisely determined from the MOT data alone. The history shows an annual testing cadence from 2021 onwards with no extended periods off the road, suggesting the vehicle has been in regular use throughout. At this accumulated mileage, the mechanical expectations should include wear on suspension bushes, coil springs, brake discs and pads, clutch and gearbox components, exhaust system mountings, and engine ancillary drive items, all of which are consistent with the age-related advisories observed. For a prospective buyer, the rear brake pipe corrosion flagged repeatedly since 2023 warrants close physical inspection. Lift any flexible inner hoses and examine the steel brake pipes running along the underbody and rear axle area for surface rust, flaking, or pitting. Corroded pipes coated in grease or contaminant can mask deeper wall thinning, and the offside rear pipes in particular have been noted in three cycles. Check the flexible hose ferrules at both rear inner positions for the slight corrosion already recorded, and verify that the brake pedal feels firm without sponginess or excessive travel, which would indicate hydraulic deterioration. On a test drive, listen for any scraping or grinding from the rear, particularly on light throttle application, which could suggest the binding offside rear caliper previously noted has progressed. The suspension and shock absorber items require direct attention given the major fluid leak recorded in November 2025. With the engine running from cold, visually inspect the nearside front shock for fresh oil seepage down the body or around the top mount, and push down firmly on each front corner to confirm the rebound is even and controlled without a secondary bounce. The advisories for the nearside front lower arm rear bush and offside front lower ball joint should prompt a check for knocking or clonking over uneven surfaces, particularly at low speed over speed humps. Additionally, the 2024 ABS warning lamp fault and 2023 electronic parking brake warning indicate possible stored electronic diagnostic trouble codes, so a scan with a Renault-compatible diagnostic tool is advisable. Verify the electronic parking brake releases cleanly on cold start and applies reliably, and confirm the ABS and handbrake warning lamps extinguish promptly during the bulb check phase. Finally, test all rear lighting functions, including the central high-level stop lamp and reversing lamps, as multiple lighting failures have appeared across the recent record.
