Is the Audi A3 reliable?

Going by its MOT results, the Audi A3 is about average: 79% of the 130,127 MOT tests on Audi A3 vehicles checked on CarCheckUp were passed, against 77% for all vehicles we checked. That places it 19th of the 59 popular models we publish figures for. Lights and indicators items are its most common reason to fail (40% of failed tests). MOT results show how often cars reach the test with a defect, not breakdowns or repair bills, so judge the one you are buying by its own MOT history and service record.

What to check on a used Audi A3

In the order the A3's MOT records suggest: the areas that fail or draw advisories most often on this model, and what to look at in each.

  1. Lights and indicators 40% of failed A3 MOT tests have a failure here; most often “Stop lamp not working” (1.2% of tests). Have someone walk round the car while you try every lamp, including the number plate, brake and fog lamps, and look for misted or cracked units.
  2. Tyres 29% of failed A3 MOT tests have a failure here; most often “Tyre tread depth below requirements of 1.6mm” (2.8% of tests). Look at the tread across the full width of all four tyres and at the sidewalls for cracks or bulges; uneven wear points to tracking or suspension faults.
  3. Suspension 28% of failed A3 MOT tests have a failure here; most often “Coil spring fractured or broken” (1.8% of tests). Drive over a rough road with the radio off and listen for knocks; push down on each corner (it should settle at once) and look for uneven tyre wear.
  4. Brakes 18% of failed A3 MOT tests have a failure here; most often “Brake pad less than 1.5 mm thick” (1.5% of tests). Look through the wheels at the discs for a raised lip, scoring or rust, ask when pads and discs were last changed, and check the handbrake holds on a slope.
  5. Windscreen and wipers 11% of failed A3 MOT tests have a failure here; most often “Windscreen washer provides insufficient washer liquid” (0.9% of tests). Check the glass for chips and cracks in the driver's view, and that the wipers clear cleanly and the washers work.

Then read the car's own record: the free MOT history check shows every failure and advisory for one registration, and the MOT advisories check explains what each note means. Of the 78 Audi A3 vehicles checked with a full CarCheckUp report, 28.2% had an insurance write-off record and 12.8% had outstanding finance: neither shows on the car or in the free check.

Key history checks before buying a used Audi A3

Outstanding Finance

A Audi on hire purchase, PCP or a logbook loan may still belong to the lender. Buying it can lead to a dispute over who owns it. Outstanding finance check

Insurance Write-Off (Cat S, N, C, D)

Shows if an insurer declared the car a total loss. Cat S and N cars can return to the road, but the record lowers the value and can affect insurance. Write-off check

Police Stolen Marker

Checks the Police National Computer. A stolen car can be taken back, leaving you without the car or your money. Stolen car check

High Risk Register

Shows if a finance company, insurer or the police has registered an interest in the A3. Find out why before you buy.

Mileage Anomaly Check & MOT History

Free: every MOT mileage reading, with advisories and failures. The full report checks them for drops (clocking) and adds mileage recorded by dealers and insurers. Mileage check

Previous Keepers & Plate Changes

How many keepers the car has had and when, plus number plate changes that can separate a car from its history. Previous owners check

Colour Changes

A respray can be harmless, or hide accident repairs or a disguised identity. Compare the recorded colour with the car.

Imported & Exported

An imported Audi can have history from abroad that UK records don't show; an export marker on a car for sale here needs explaining.
