2014 Audi TT — MOT failures & pass rate
Across 22,188 MOT tests, the 2014 Audi TT recorded an 88.8% pass rate. Against coupes & convertibles of a similar age (13.2% fail rate), the 2014 TT comes out 2.0pp better. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (4.8%) and lighting & signalling (3.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, headlamp aim and washers — tread depth alone was recorded 746 times.
A 150k+ example is materially riskier than a 0-30k one: 30.6% versus 5.3%.
The petrol cars hold up better: 10.2% fail against 13.0% for diesel, a 2.8-point gap across 22,188 tests.
Tyres is the most common advisory, noted on 23.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.9% of tests failed in 2021 against 13.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2014 TT
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.8% of tests. Start there.
- 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 (3.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.7% 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.
