2019 Audi Q3 — MOT failures & pass rate
The 2019 Audi Q3 passed 93.2% of its 60,452 recorded MOT tests. Small SUVs of a similar age fail 8.8% of the time, so this is 2.0pp better than the group it competes with. Failures cluster in tyres, brakes and visibility.
What the MOT record shows
No single area dominates — tyres (3.9%) and brakes (1.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, brake pads and washers — tread depth alone was recorded 1,211 times.
Mileage matters less than usual here: the 2019 Q3 fails 5.1% of the time in the 0-30k band and 7.1% at 120-150k, a spread of only 2.1 points.
Fuel type barely separates them — petrol fails 6.6% of the time against 7.6% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 23.5% of tests without failing them.
The trend is worsening — 3.5% of tests failed in 2021 against 7.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 Q3
On a 2019 Q3, tyres is what the MOT record says goes wrong most — it appeared in 3.9% of tests. Check these areas before you commit.
- Tyres (3.9% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Brakes (1.9% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Visibility (1.3% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
