2000 Audi S3 — MOT failures & pass rate
Across 547 MOT tests, the 2000 Audi S3 recorded a 76.8% pass rate. Small family cars of a similar age fail 27.7% of the time, so this is 4.4pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 16.8% of all tests — 5.3 points clear of suspension, so it is the first thing to check.
At component level the recurring items are headlamp aim, catalyst emissions and headlamp — headlamp aim alone was recorded 56 times.
Condition tracks the odometer closely. Failures run at 15.0% in the 60-90k band and 26.2% in the 150k+ band, a 11.2-point spread.
Advisories point at the next bill rather than this one: suspension was flagged on 33.5% of tests without failing them.
The trend is worsening — 19.5% of tests failed in 2021 against 21.4% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 33.5% | 183 |
| 2 | Brakes | 32.7% | 179 |
| 3 | Tyres | 21.4% | 117 |
| 4 | Emissions & environmental | 17.7% | 97 |
| 5 | Lighting & signalling | 13.4% | 73 |
| 6 | Body, structure & corrosion | 13.2% | 72 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 60 | 15.0% |
| 90-120k | 99 | 26.3% |
| 120-150k | 141 | 22.0% |
| 150k+ | 225 | 26.2% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2000 S3
On a 2000 S3, lighting & signalling is what the MOT record says goes wrong most — it appeared in 16.8% of tests. Check these areas before you commit.
- Lighting & signalling (16.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (8.8% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
