2015 Audi Q3 2.0L Diesel · H84 TEY

The 2015 Audi Q3 has demonstrated a concerning pattern of MOT failures over the past two years, despite passing its most recent test on 19 August 2025—just seven days before the current date. The last two tests, both within a single month in August 2025, reveal a lack of consistency, with no recorded defects on either occasion, though the failure on 9 August at 182,572 miles suggests a narrowly avoided re-test. This instability, combined with the absence of any advisory notes in the official record, implies either a high degree of luck in passing or a history of last-minute repairs. The 2024 failures at 172,689 and 173,302 miles—just 613 miles apart—further underscore a trend of unresolved issues, though again, no specific faults were logged. Without visible advisories or defects, the MOT history does not provide clarity on whether the vehicle has undergone critical maintenance or if recurring problems were overlooked. The recorded mileage of 185,463 miles over approximately 11 years equates to an average of 16,860 miles annually, which is unusually high for a vehicle of this age. This rate of accumulation suggests either consistent heavy use or prolonged periods of neglect between services. Notably, the gap between the 2023 and 2024 tests spans 12 months, with mileage increasing by 9,717 miles—a pattern that repeats between 2024 and 2025, where another 12,861 miles were covered in just over a year. Such rapid mileage suggests the vehicle was actively driven rather than stored, which could accelerate wear on components like suspension bushes, coil springs, and drivetrain synchronisers. The absence of any advisory notes in the MOTs also raises questions about whether intermediate checks were performed, as high-mileage vehicles often require more frequent attention to prevent catastrophic failures. Given the lack of specific defects in the MOT record, a buyer should prioritise an independent inspection of high-wear areas that are not routinely tested. The suspension—particularly the rear coil springs and bushes—should be examined for uneven wear or corrosion, as these components are critical for handling and safety at this mileage. Brake systems, including caliper binding and disc thickness, warrant close scrutiny, especially if the vehicle has been driven hard, as excessive heat can accelerate wear. The drivetrain, including the constant velocity (CV) joints and differential, should be checked for fluid leaks or unusual noise, as these are often silent failures until they become severe. Structural integrity, particularly around wheel arches and sills, should also be assessed for corrosion, as Audi models from this era are prone to rust-related issues in high-exposure areas. The absence of advisories in the MOT history does not guarantee these areas are sound, so a thorough mechanical examination is essential.
