Every Audi S3 model year
Pass rates fall as cars age, so the only fair comparison for a 2009 car is other cars of the same age. The full run for the Audi S3:
| Year | Pass rate | Tests | Avg mileage |
|---|---|---|---|
| 2007 | 78.8% | 321 | 116,098 |
| 2008 | 80.7% | 274 | 113,677 |
| 2009 | 82.1% | 263 | 101,520 |
| 2010 | 78.4% | 347 | 95,856 |
| 2011 | 78.8% | 293 | 89,124 |

What this means if you are buying a 2009 S3
The 2009 sits close to the Audi S3 average, so there is no strong model-year signal either way. Judge the individual car on its own history. Check the exact car with the free MOT history checker before you buy, and run its VIN and mileage through our free VIN decoder and clocking check.
What a 17-year-old car fails on
A 2009 car is 17 years old now, and age drives the failure mix more than the badge does. Across all cars tested, these are the categories that actually cause failures:
- Lights and electrical: 10.36% of all cars tested
- Suspension: 8.65% of all cars tested
- Tyres: 6.23% of all cars tested
- Brakes: 6.1% of all cars tested
- Visibility: wipers, washers, glass: 4.65% of all cars tested
- Body, chassis and structure: 3.18% of all cars tested
That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust. On a 2009 Audi S3 the average at test was 101,520 miles, so treat anything far above that as a car that has worked harder than its peers, and anything far below as one worth checking for the faults that come from standing still.
The strongest year for this model is 2014 at 86.6%, and the weakest in our data is 2010 at 78.4%. That 8.2 point spread across the model's life is why comparing a 2009 car against a newer one tells you very little.
