2015 Audi Q7 3.0L Diesel · DN65 VDZ

The 2015 Audi Q7 has passed its most recent MOT on 7 February 2026, just five months ago at 101,069 miles, but the record reveals a concerning trend in tyre and driveline maintenance. While the vehicle cleared inspection without major defects in the latest test, the near-side front driveshaft CV joint boot deterioration (6.1.7 (g) (i)) indicates a critical failure risk if left unaddressed. This fault, though not yet severe enough to fail the test, suggests fluid leakage into the joint, which will accelerate wear and could lead to sudden driveshaft failure—a serious safety hazard. The absence of similar advisories in earlier tests implies this issue has emerged recently, likely due to neglect or a lack of proactive servicing. The mileage progression shows an average of around 9,200 miles per year, which is typical for a vehicle of this age and usage profile. There are no unusually long gaps between tests, though the jump from 62,380 miles in August 2022 to 78,155 miles by July 2023—covering just 15,775 miles in under a year—suggests either intensive use or a period of higher mileage accumulation. The most notable pattern is the repeated tyre-related advisories in September 2024, where both rear tyres and the offside front tyre were worn close to the legal limit and unevenly. This failure to address tread depth consistently over 15,000 miles indicates a pattern of deferred maintenance, potentially compromising wet-weather handling and increasing the risk of blowouts. A buyer should prioritise an immediate inspection of the near-side front driveshaft CV joint boot, which is now visibly deteriorated and likely leaking grease. The joint itself should be flexed for play or roughness, as fluid loss will accelerate wear and could lead to a catastrophic driveshaft separation. The suspension components, particularly the rear subframe mounts and bushings, warrant close scrutiny given the vehicle’s age and mileage, as these are common failure points in Q7 models. The repeated tyre advisories demand verification of current tread depth and uniformity, with a focus on the rear axles and offside front, where edge wear suggests misalignment or uneven loading. Structural corrosion should also be checked at wheel arches, sills, and the rear subframe, as this model is prone to rust progression in high-exposure areas. Finally, the exhaust system and catalytic converter should be inspected for leaks or excessive corrosion, as these are often overlooked but critical to both emissions compliance and structural integrity.
