2019 Audi TT — MOT failures & pass rate
Across 19,858 MOT tests, the 2019 Audi TT recorded a 93.3% pass rate. Against coupes & convertibles of a similar age (8.6% fail rate), the 2019 TT comes out 1.9pp better. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
Tyres dominates the failure mix at 4.8% of all tests — 3.5 points clear of lighting & signalling, so it is the first thing to check.
At component level the recurring items are tread depth, headlamp aim and brake pads — tread depth alone was recorded 626 times.
A 90-120k example is materially riskier than a 0-30k one: 13.9% versus 5.3%.
Advisories point at the next bill rather than this one: tyres was flagged on 21.6% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 5 | Suspension | 1.8% | 350 |
| 6 | Lighting & signalling | 0.3% | 50 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

| 0-30k | 12,649 | 5.3% |
| 30-60k | 6,531 | 9.0% |
| 60-90k | 633 | 10.6% |
| 90-120k | 36 | 13.9% |

What to check before buying a 2019 TT
On a 2019 TT, tyres is what the MOT record says goes wrong most — it appeared in 4.8% of tests. Check these areas before you commit.
- Tyres (4.8% 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.
- Lighting & signalling (1.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (0.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
