Most common owner-maintenance faults
DVSA wording grouped as owner maintenance for this model and age band.
- 1
Tyre worn close to legal limit/worn on edge
23,003 notes5.2.3 (e)What it means, why it happens, what to check
What it means
- Tread is close to (or at) the legal minimum, or wear is concentrated on an edge. That often points to alignment, pressure or suspension issues as well as simple age.
Why it happens
- Under-inflation, poor alignment, aggressive driving or simply delayed replacement push tread below a safe/legal profile.
Buyer tip
- Measure tread across the full width, check tyre age (DOT date) and look for uneven inner-edge wear.
Severity
- Usually maintenance related
- 2
Shock absorbers has light misting of oil
5,886 notes5.3.2 (b)What it means, why it happens, what to check
What it means
- A damper mounting bush is worn, which can cause knocks, vague handling and accelerated tyre wear.
Why it happens
- Rubber bushes harden and tear with age, road salt and repeated suspension movement.
Buyer tip
- Listen for clunks over speed bumps and have a mechanic check top mounts and lower bushes.
Severity
- Usually maintenance related
- 3
Headlamp aim too low
871 notes4.1.2 (a)What it means, why it happens, what to check
What it means
- This MOT defect usually indicates incorrect headlamp alignment following adjustment, suspension movement or repair work.
Why it happens
- Aim drifts after suspension work, bumper repairs, bulb changes or simply from road vibration over time.
Buyer tip
- Check beam alignment during inspection and ask whether the lamps were aimed after any recent suspension or bodywork.
Severity
- Usually maintenance related
- 4
Windscreen washer not working
478 notes3.5 (a)What it means, why it happens, what to check
What it means
- Washer jets are not delivering fluid. Testers need a clear screen; empty reservoirs, blocked jets or failed pumps are common.
Why it happens
- Empty bottles, frozen/blocked jets, split pipes or a failed pump stop fluid reaching the screen.
Buyer tip
- Top up fluid, test the jets on the driveway, and check for cracked bottles or split pipes in the engine bay.
Severity
- Usually maintenance related
- 5
Supplementary restraint system warning lamp indicates a fault
191 notes7.1.6 (a)What it means, why it happens, what to check
What it means
- The airbag/SRS warning lamp indicates a fault. Restraint systems may not deploy correctly in a collision.
Why it happens
- Clock-spring, sensor or module faults — sometimes after prior accident repairs — set SRS warnings.
Buyer tip
- Require a specialist SRS diagnosis — do not accept a bulb removed or lamp covered up.
Severity
- Usually maintenance related
- 6
Tyre pressure monitoring system malfunctioning or obviously inoperative
146 notes5.2.3 (h)What it means, why it happens, what to check
What it means
- The tyre pressure monitoring system is reporting a fault or is clearly not working, so you may not get a dashboard warning of under-inflation.
Why it happens
- Flat battery sensors after tyre changes, damaged valves or control-module faults are common.
Buyer tip
- Confirm whether sensors need replacing after recent tyre or wheel work, and check pressures manually anyway.
Severity
- Usually maintenance related
- 7
Seat belt webbing slightly damaged or frayed
92 notes7.1.2 (b)What it means, why it happens, what to check
What it means
- Seat-belt webbing is frayed or lightly damaged, which can weaken the belt in a crash.
Why it happens
- Abrasion at guides, trapped belts or age fray the webbing fibres.
Buyer tip
- Pull each belt fully out and inspect for cuts, fraying and weak retraction.
Severity
- Usually maintenance related
- 8
Tyre obviously under inflated
66 notes5.2.3 (l)What it means, why it happens, what to check
What it means
- This wording appears on DVSA MOT records for this model. It flags a tester-observed defect or advisory that can affect safety, legality or a future pass.
Why it happens
- These issues often build up when routine checks are skipped between services — tyres, lamps and washers are typical examples.
Buyer tip
- Ask the seller for invoices covering this item, and have an independent inspector confirm whether it is still present.
Severity
- Usually maintenance related
Most common wear & tear faults

Severity
- Usually wear related
- 2
Rear Service brake binding but not excessively also pads are worn a little more than offside
1 notes1.2.1 (f)What it means, why it happens, what to check
What it means
- Service brake performance could not be fully verified, or a brake is binding/fluctuating. That often points to worn discs, seized calipers or hub issues.
Why it happens
- Seized caliper slides, worn discs or contaminated friction material upset brake balance.
Buyer tip
- Insist on a road test and a proper brake inspection; unresolved binding can destroy pads and hubs.
Severity
- Usually wear related

Audi A3 research summary
Based on over 79,235 official UK MOT tests, Audi A3 models registered between 2021 and 2026 achieve a strong 89.7% MOT pass rate.
The overwhelming majority of recorded MOT defects relate to routine owner maintenance, with tyres, dampers and lighting accounting for most common faults seen on used examples in this age band.
Recurring systemic faults occur far less frequently, although engine management warning lamp (MIL) defects appear consistently across the dataset.
Overall, the data suggests that this generation of Audi A3 is more likely to fail MOT due to maintenance items than widespread design faults, making service history and routine upkeep particularly important when buying used. Shoppers comparing a used Audi A3 should treat this research summary as model-level context before inspecting any individual car.
What this report cannot tell you
This report describes model-level MOT trends, not the condition of any individual vehicle.
Two identical Audi A3 models can have very different maintenance histories.
Use it to understand common patterns before inspecting a specific car — then check that car’s own MOT history.

How we classify MOT faults
We group recorded DVSA defect wording into four research categories to help identify whether issues are more likely to reflect routine maintenance, expected wear, recurring model patterns or miscellaneous inspection outcomes.
- Owner maintenance
- Defects often linked to day-to-day upkeep — tyres, lamps, washers and other items a careful owner can usually prevent or fix promptly.
- Wear & tear
- Age- and mileage-related deterioration that accumulates with normal use, even when a car has been looked after.
- Systemic
- Recurring wording and patterns across the model fleet that may point to design, component or known-model tendencies rather than one careless owner.
- Other
- Inspection outcomes that do not sit cleanly in the three groups above, including mixed or less classifiable defect notes.
