2021 Audi Rs Q3 Vsprung Sa — MOT failures & pass rate
Across 517 MOT tests, the 2021 Audi Rs Q3 Vsprung Sa recorded a 94.2% pass rate. All cars of a similar age fail 8.6% of the time, so this is 2.8pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — tyres (3.5%) and lighting & signalling (1.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, catalyst emissions and washers — tread depth alone was recorded 8 times.
Advisories point at the next bill rather than this one: tyres was flagged on 14.7% of tests without failing them.

What to check before buying a 2021 Rs Q3 Vsprung Sa

- Lighting & signalling (1.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (1.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
