2011 Audi TT — MOT failures & pass rate
37,943 MOT tests on the 2011 Audi TT are in this dataset, and 83.9% of them passed. Against coupes & convertibles of a similar age (17.9% fail rate), the 2011 TT comes out 1.7pp better. Failures cluster in suspension, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (6.8%) and tyres (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, linkage ball joint dust cover and coil spring — tread depth alone was recorded 1,449 times.
Condition tracks the odometer closely. Failures run at 7.0% in the 0-30k band and 22.5% in the 150k+ band, a 15.5-point spread — more than double.
Fuel type barely separates them — petrol fails 15.6% of the time against 17.1% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 24.1% of tests without failing them.
The trend is worsening — 13.9% of tests failed in 2021 against 18.2% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2011 TT
On a 2011 TT, suspension is what the MOT record says goes wrong most — it appeared in 6.8% of tests. Check these areas before you commit.
- Suspension (6.8% 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.
- Tyres (5.1% 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 (4.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
