2015 Audi Q3 2.0L Diesel · FV65 AYS

Recurring issues with suspension components and brake line corrosion define the mechanical profile of this Audi Q3, with the most recent test on 06 February 2026 showing a pass following a dangerous failure for insufficient tyre tread depth. The MOT history reveals a persistent pattern of advisories concerning the nearside front shock absorbers exhibiting oil misting and corrosion on both rear suspension arms, which have been noted in consecutive years since at least 2024. While the most recent result shows no defects, the presence of long-term advisories for structural corrosion and component wear suggests a trend of progressive degradation in the vehicle's underbody and suspension systems. The vehicle has covered 74,942 miles over its eleven-year lifespan, averaging approximately 6,813 miles per year. This represents a relatively low annual mileage for a vehicle of this age, which can sometimes correlate with less frequent mechanical movement or longer periods of inactivity. While lower mileage generally implies less wear on high-friction drivetrain components, the recorded history of suspension arm corrosion and shock absorber misting indicates that environmental factors or road salt exposure may be impacting the chassis integrity despite the moderate usage levels. A physical inspection and test drive should focus heavily on the documented suspension and braking concerns. The repeated advisories for corrosion on the nearside and offside rear suspension arms, alongside the noted corrosion on the offside rear brake hose ferrule, necessitate a close examination of the rear axle area. During a test drive, listen for any knocking, clunking, or irregular thumping sounds when traversing uneven surfaces or speed bumps, which could indicate that the previously noted corrosion or the fractured coil spring issues from 2025 have progressed. Additionally, pay close attention to the steering response and any potential pulling to one side, which may stem from the ongoing issues with the front shock absorbers and anti-roll bar linkages. Regarding the braking system, the history of brake hose deterioration and ferrule corrosion should be monitored for any changes in pedal feel. Any sensation of pedal sponginess, vibration, or judder during braking could indicate that the reported hose issues have worsened. Given that the vehicle has previously failed on dangerous tyre defects, including exposed cords and insufficient tread, the current state of all four tyres should be verified for even wear and adequate depth. The reported oil misting on the nearside front shock absorber should also be checked to ensure it has not developed into a significant leak that could compromise damping performance.
