What to look out for
Engine: All Q3s are fitted with a cambelt. There’s no mileage interval for changing it, but Audi recommends replacing it every five years, at a cost of £600.
Gearbox: Manuals are susceptible to clutch judder. Garages might try to get you to change the dual-mass flywheel (£1000-plus) but check the forums for cheaper solutions.
Suspension: Many owners have reported a frustrating clunking from the front suspension at low speeds. It’s especially noticeable when turning or going over speed bumps. The cause has not yet been identified, but poorly fitted components, premature wear and insufficient lubrication commonly appear on the shortlist of potential reasons.
Build quality: Rattles around the cabin have been reported by some owners, particularly a buzzing sound in the passenger footwell/door area due to a known issue with the fuel line, which is often fixed under warranty but can return.
Sunroof: Leaks are common. Cleaning the drains at regular intervals can help. A special tool for this is available online.
Also worth knowing
All Q3 models are ULEZ-compliant. Insurance groups begin at a reasonable 21 but rise as high as 40 for the hot RS Q3.
As for tax, most Q3s are £195 each year. However, those younger than five years old and with a list price of more than £40,000 (you would be surprised how many cars in S Line trim and above fit this bill) will be £620 per year until their fifth birthday. On the flip side, some will still be less than three years (and 60,000 miles) old so will be covered by Audi’s standard warranty. An extended warranty can be purchased for older models, should you want it.
