2016 Infiniti Q30 2.1L Diesel · MM16 XBY

The vehicle remains roadworthy but the maintenance trend shows a persistent failure to address underlying brake system corrosion. While the most recent test in November 2025 at 74,258 miles passed, the tester again flagged corroded front brake pipes covered in grease. This specific issue is recurring, having appeared in the November 2024 and 2023 records, suggesting that previous owners have opted for minor repairs or cleaning to pass the test rather than replacing the affected components to prevent long-term degradation of the hydraulic lines. At 74,258 miles over ten years, the car has covered an average of approximately 7,400 miles per year, which aligns with typical UK usage patterns for its age. The mileage progression shows consistent use between annual tests, with roughly 3,000 to 4,000 miles accumulated between the 2022 and 2025. This regularity suggests the vehicle has not sat for extended periods, though the low mileage explains the perishing of rubber components like tyres as noted in earlier advisories. A buyer must conduct a thorough physical inspection of the front braking system to ensure the corrosion on the pipes has not compromised their structural integrity. The presence of grease on these pipes often indicates an attempt to hide leaks or rust, which warrants a close check for thinning. Additionally, the suspension requires attention following the failure for a fractured offside front coil spring in November 2024. Although this was rectified to pass the test, the buyer should check the remaining springs and bushes for signs of wear, as the history of perishing tyres and worn brake discs indicates a reactive maintenance approach rather than proactive care.
