2016 Audi Q3 2.0L Diesel · WF66 CWT

The defining mechanical story for this Audi Q3 is a pair of persistent brake disc advisories on the front axle, recorded at both the 2025 and 2024 tests, alongside a cluster of minor windscreen damage entries that have appeared on four consecutive examinations. At the most recent assessment on 12 September 2025 the vehicle passed without any failure items, but the front brake discs were once again flagged as worn, pitted, or scored though not seriously weakened, repeating the exact same advisory from September 2024. The fact that both nearside and offside front discs were noted in successive years suggests an ongoing surface degradation pattern rather than a one-off observation, and this is the primary mechanical risk a buyer should weigh against an otherwise pass-laden history. The windscreen has shown damage on the offside upper region since 2022, with a further minor entry in 2024, but each was assessed as not adversely affecting the driver's view, keeping these as cosmetic monitor items rather than immediate defects. With 61,375 miles recorded over a ten-year span, the Q3 has averaged roughly 6,138 miles annually, which sits broadly in line with typical usage for a vehicle of this age and class. There are no significant gaps in the testing record between 2019 and 2025, indicating the car has remained in continuous road use rather than being laid up for extended periods, which reduces the likelihood of dormant corrosion issues or stale fluid-related concerns. The mileage progression across the recorded tests is steady and consistent, suggesting the vehicle has been driven regularly enough to keep mechanical components working as intended, although the accumulating front brake disc wear is a natural consequence of that ongoing use given the braking loads carried by the front axle. For a prospective buyer, the front braking system should be the focal point of any physical inspection and test drive. The repeat advisory on both front discs indicates the friction surfaces are likely nearing minimum thickness or developing lipping and roughness, so listen for any brake-related noises such as grinding, squealing, or a rhythmic thumping under pedal application, and feel for vibration or pulsation through the steering wheel when braking from higher speeds. On a test drive, pay particular attention to the effectiveness of the initial bite and whether the pedal feels spongey or requires excessive travel, as worn discs on an Audi of this generation often correlate with glazed pad material. Inspect the discs visually through the wheel spokes for a pronounced outer lip and any blueing from overheating, and check that the calipers are sliding freely without binding, as seized guide pins will accelerate uneven disc wear. Beyond the brakes, the rest of the record offers relatively little to interrogate, but a few targeted checks remain worthwhile. The 2022 advisory for a nearside rear tyre showing slight damage or cracking is worth a current visual check of all four tyres for sidewall perishing, cracking, or bulging, particularly given the vehicle's age and exposure to UK weather. The recurring windscreen damage entries on the offside upper area should be inspected for any spreading cracks that could now fall outside the driver's line of sight tolerances at a future test. Finally, given that this is a 2016 Q3 approaching a decade in service, a general underside examination for any emerging corrosion on suspension arms, subframe mounting points, and brake pipe runs would be prudent, even though no such items have yet been flagged in the MOT data.
