Common Issues to Watch For
Based on the 2015 AUDI Q3's fuel type, age, and engine size, these are the most likely problem areas to check.
Rust and Corrosion
Watch outAt 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.
Suspension Bushings
Watch outRubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.
Service History
Low riskAlways request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
