AUDI A3 Common Problems & Reliability

Based on 34,250 MOT tests from 3,204 vehicles analysed by VehicleScore. The figures below describe that VehicleScore sample. Recurring issues seen in VehicleScore MOT data are not a claim that every AUDI A3 has the same fault.

AUDI A3's have a slightly over average reliability rating of 593/999. The score was calculated from the average of every AUDI A3 that has had a registered MOT.

We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Also check BHP & performance, road tax, fuel economy, and CO2 emissions for the AUDI A3.

Common AUDI A3 MOT problems

These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.

Tyre wear

VehicleScore MOT data includes 6,425 advisory comments and 793 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: OFFSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake pad wear

VehicleScore MOT data includes 1,200 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

What to inspect

Ask for recent pad replacement and look at the remaining pad thickness.

Example MOT wording: REAR BRAKE PAD(S) WEARING THIN (1.1.13 (A) (II))

Brake disc wear

VehicleScore MOT data includes 1,103 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake discs that were worn, scored, pitted, or corroded.

What to inspect

Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

Example MOT wording: REAR BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))

Oil leak

VehicleScore MOT data includes 746 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.

What to inspect

Look under the engine for fresh oil, and check the oil level.

Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))

Coil spring issues

VehicleScore MOT data includes 618 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record coil springs that were corroded, fractured, or otherwise defective. They are counted separately from shock absorbers.

What to inspect

Look for a broken or heavily corroded spring and compare the ride height on both sides.

Example MOT wording: OFFSIDE FRONT COIL SPRING FRACTURED OR BROKEN (5.3.1 (B) (I))

Corrosion

VehicleScore MOT data includes 419 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record corrosion the tester could see on the body or structure. Corrosion already named on a spring, brake, or other component is counted with that component.

What to inspect

Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.

Example MOT wording: REAR SUB-FRAME CORRODED BUT NOT SERIOUSLY WEAKENED (5.3.3 (B) (I))

Anti-roll bar issues

VehicleScore MOT data includes 213 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record wear or damage in the anti-roll bar, its links, or its bushes.

What to inspect

Listen for a knock when driving over uneven ground at low speed.

Example MOT wording: OFFSIDE FRONT ANTI-ROLL BAR LINKAGE BALL JOINT DUST COVER NO LONGER PREVENTS THE INGRESS OF DIRT (5.3.4 (B) (II))

Parking brake faults

VehicleScore MOT data includes 112 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a parking brake that did not hold well enough or had a component defect.

What to inspect

Test that the parking brake holds the car on a slope and releases cleanly.

Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))

What to check when buying a used AUDI A3

This is an inspection checklist based on MOT comments in the VehicleScore sample. It does not mean the car you are looking at has these defects.

Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Coil spring issues. Look for a broken or heavily corroded spring and compare the ride height on both sides.
Corrosion. Inspect the underside, sills, and subframe for heavy corrosion, especially where an advisory mentions it.
Anti-roll bar issues. Listen for a knock when driving over uneven ground at low speed.
Parking brake faults. Test that the parking brake holds the car on a slope and releases cleanly.

Buying a AUDI A3?

Common problems tell you what can affect AUDI A3s generally. VehicleScore can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
