Audi A3 reliability by year, 2000 to 2022

1,249,310 Audi A3s went through an MOT in the period we analysed, and 75.2% passed. Set against the 71.7% national pass rate, that is a good result on the raw numbers. Allowing for age, the A3 beats a typical car tested at the same age by 5.2 points. That is the fairer test, and it puts the model above average. At its first MOT, at three years old, 89.1% of A3s pass; the national figure for three-year-old cars is 87.9%. When a A3 does fail, tyre tread below the legal minimum is the item recorded most often.

What fails a Audi A3 at its MOT

The A3's failures cluster around tyres and suspension: tyre tread below the legal minimum on 11.4% of fails, a broken coil spring on 8.3%. Percentages can add to more than 100 because one failed test often records several defects.

1Tyre: tread below the 1.6mm legal minimum11.4%
2Coil spring: fractured or broken8.3%
3Brake pads: less than 1.5 mm thick5.6%
4Tyre: deep cut reaching the cords5.4%
5Tyre: cords exposed4.8%
6Number plate light: not working4.2%

A tyre fail usually means a tyre that was already an advisory last year. Worth looking at the previous certificate before booking.

Advisories to expect on a A3

An advisory is the tester telling you what fails next year. On the A3 the usual suspects are tyre tread below the legal minimum (17.3% of tests) and worn brake discs (9.8%). The advisory conversion table shows which of these are worth acting on first.

Tyre: tread below the 1.6mm legal minimum17.3%
Brake discs: seriously weakened9.8%
Brake pads: less than 1.5 mm thick6.4%
Tyre: sidewall tear or separation5.1%
Suspension bush: excessively worn4.8%

Does fuel type matter on a A3?

Among Audi A3 cars, hybrid versions pass 85.8% of the time and diesel versions 70.2%, a gap of 15.6 points. Diesels tend to be bought for high mileage, which shows up at the test as wear. Hybrid versions are newer cars on average, so some of that gap is age rather than engineering.

Audi A3 pass rate by year

Between 2000 (59.1%) and 2022 (89.2%) the pass rate moves mostly with age. Among years with a decent sample, 2022 is the strongest at 89.2% and 2004 the weakest at 52.8%.

Mileage matters more than the badge

On the 2015 cars, a A3 under 40,000 miles passes 89.9% of the time; one over 100,000 passes 75.6%. When comparing two used A3s, the odometer tells you more than the year.

Compared with other cars

Set against the rest of the Audi range, which averages 78.1%, the A3 at 75.2% is below par. Within the family, see Audi A4 MOT pass rate (72.8%), Audi A1 reliability (77.2%), Audi Q3 reliability (83.3%) and how the A6 does (79.3%), or Audi reliability by model. Buyers weighing a A3 against other cars of similar popularity often compare it with the Mercedes-Benz C-Class (74.3%) and Fiat 500 (68.3%). The reliability index for all makes and models puts them side by side, and the statistics for all 98 million tests give the baseline.

Questions people ask

Is the Audi A3 reliable?

On MOT evidence the Audi A3 is above average. It passes 75.2% of tests against 71.7% for all cars, and beats cars of the same age by 5.2 points. 89.1% pass their first MOT at three years old. Figures from 1,249,310 DVSA tests.

What are the most common Audi A3 MOT failures?

Tyre tread below the legal minimum (11.4% of failed tests), a broken coil spring (8.3%) and brake pads worn below 1.5mm (5.6%). A tyre fail usually means a tyre that was already an advisory last year. Worth looking at the previous certificate before booking.

Which Audi A3 year is the most reliable?

Among years with a large sample, 2022 cars have the highest pass rate at 89.2% and 2004 cars the lowest at 52.8%. Newer years pass more because they are younger, so compare a specific car's year against the table above rather than against the overall figure.

What advisories does a Audi A3 usually get?

Tyre tread below the legal minimum is the most frequent, noted on 17.3% of all A3 tests, then worn brake discs (9.8%). An advisory passes the car today but marks the item most likely to fail next year.

How many miles a year does a Audi A3 do?

About 8,517 miles a year on average, calculated from the odometer readings recorded at consecutive MOTs. That is close to the UK average of roughly 7,400.

How do I check a particular Audi A3?

The figures describe the whole fleet. For one car, enter its registration in the free MOT check to see its own test history, advisories and mileage, set against these averages for its year.

Checking a A3 before you buy?

Enter the registration to see its own MOT history, advisories and mileage set against these figures, including whether it has done more or fewer than the 8,517 miles a year typical of the model.
