Audi S3 2022: reliability & common MOT faults

In 2025, 90 in every 100 first MOTs on a 2022 Audi S3 were passes. Most common reason for a fail: Tyre condition (front).

Summary

The 2022 Audi S3 follows the pattern of the model years either side.

What failed most often

  1. Tyre condition (front)48 in every 100 failed tests

How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.

Note:

These are patterns across 2022 Audi S3 vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.

Tyres

Two wear patterns. The strongest is the tyre tread depth (rear): 5.9 times as often as on similar cars.

Figures below are measured across the 149 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.

We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.

Tyre tread depth (rear)

Failed on 23 first tests5.9 times as often as similar carsWear pattern

What it means

Only primary grooves count when tread depth is assessed: those holding the wear indicators, or cut as deep as those when new. Shallower secondary grooves are ignored. Tread depth below the minimum for the vehicle is Dangerous, and so is a pattern not visible over the whole tread, but that second row applies only to vehicles that need the lower minimum.

Also noted as an advisory

Testers also noted it as an advisory, worn but not yet failing, on 38 first tests, 3.4 times as often as on similar cars.

Tyre condition (front)

Failed on 71 first tests2.2 times as often as similar carsWear pattern

What it means

Exposed or damaged ply or cords are graded Dangerous. A cut in excess of the requirements and deep enough to reach the ply or cords is Major, and testers may open the cut with a blunt instrument to check its depth. A tyre contacting the vehicle through flexing or suspension movement is not a defect; fouling fails only at the time of test.

Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.

MOT pass rates

How first tests ended, and how the pass rates are counted.

Passed first time
90in every 100
Passed on the first test.

Failed, then fixed at the test station the same day.

Did not pass, and were not fixed at the test station.

First-attempt pass 90.3% of 1,535 first tests (2025): only cars that passed first time count. Official-style pass 91.4%: cars fixed at the test station also count as a pass. The 1 fixed and the 9 not fixed make the 10 in every 100 that did not pass first time.

FAQs

Short answers about how to read this model-year guide.

The 2022 Audi S3 follows the pattern of the model years either side. In 2025, 90.3% of 1,535 first MOTs on the 2022 Audi S3 passed first time (PRS: items fixed at the station the same day, counted as a fail). The official-style rate including PRS is 91.4%. Among 149 failed first-attempt MOT tests (test year 2025), we highlight MOT failure patterns that show up more often than on cars of a similar age and mileage when the sample is large enough to trust. There is no single reliability score here; this is a pre-purchase checklist built from DVSA open data, not a guarantee for any individual car.
Ranked by how often they were actually recorded, the items that most often failed a 2022 Audi S3 at the first attempt were Tyre condition (front) (47.7%), each as a share of the year's failed first attempts. That is what goes wrong most often on the car. The common faults table shows a different measure: faults that are unusual compared with similar cars.
This page highlights MOT failure patterns for the 2022 Audi S3 (registration year) using UK DVSA open data for the selected test year. Patterns are compared with cars of a similar age and mileage. It is a buyer checklist from MOT defect statistics, not a full service history or manufacturer service-bulletin list.
No. MOT tests do not cover engine internals, gearboxes, or many electronic modules. Patterns here come from MOT defect statistics only and should not be read as engine or gearbox reliability scores.

About this data

How this page is built and what it can (and can't) say.

These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.

2024 2025

What we include

UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.

Same-day repairs

PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.

How we compare

We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.

What this does not cover

  • MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
  • Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
  • Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
  • If the data for a car is too thin to say anything useful, we say so rather than guess.
