2017 Audi Q3 2.0L Diesel · AS10 VSS

The most recent MOT, carried out on 1 October 2025, was passed but returned three advisories: the front brake disc shows wear, pitting or scoring; the near‑side front tyre exhibits slight sidewall cracking or perishing; and the previous year’s advisory concerning the front suspension arm pin or bush and the rear lower‑arm bushes remains relevant. Over the seven‑year MOT record the vehicle has moved from a clean slate in 2020‑2022 to a modest increase in wear‑related advisories, indicating a maintenance trend that is beginning to show age‑related deterioration rather than improvement, though none of the items have yet reached a failure threshold. At 48,994 mi the 2017 Audi Q3 averages roughly 5,400 mi per annum, well below the typical 10‑12 000 mi expected for a vehicle of its class. Such low utilisation often points to periods of limited use or prolonged storage, which can be gentler on high‑wear components such as the engine, transmission and drivetrain but can accelerate the ageing of rubber and electrolyte‑based parts. The modest annual mileage suggests that consumables like brake pads, tyres and suspension bushings may have more calendar‑driven wear than mileage‑driven wear, and that any sudden spikes in usage could expose latent weaknesses. Prospective buyers should give particular attention to the front braking system. Measure the disc thickness against the manufacturer’s minimum specification and inspect for deep scoring that could cause brake shudder or reduced stopping power; a replacement is likely within the next 5‑10 000 mi if the wear is already evident. The near‑side front tyre’s sidewall should be examined for cracks, dry rot or bulges, and the tyre’s DOT date confirmed – tyres older than six years are prone to perishing regardless of tread depth and should be replaced pre‑emptively. The front lower‑arm pin or bush and the rear lower‑arm bushes, flagged in 2023, merit a hands‑on check for excessive play, uneven tyre wear or clunking noises when negotiating bumps; any looseness may indicate the need for bush replacement to preserve alignment and handling. Verify that the adult seat‑belt anchorage behind the rear child seats is fully accessible and functional, as the MOT could not inspect them directly. Given the vehicle’s age and low mileage, a thorough visual and tactile inspection of age‑related items is advisable. Examine the tyre sidewalls for age cracking, the battery terminals for corrosion and test the battery’s cranking voltage, as standing can diminish charge capacity. Inspect the brake fluid for moisture content – a fluid change is recommended at least every two years – and confirm that the engine oil, coolant and transmission fluids have been serviced on schedule. Look for rust or corrosion on the under‑body, wheel arches and suspension components, especially around the front subframe where water can collect during storage. Finally, request a complete service book to verify that oil changes, filter replacements and any scheduled component checks have been logged, providing confidence that the low‑mileage Q3 has been maintained in line with Audi’s service intervals.
