Audi A5 common problems and MOT failures

What goes wrong on a used Audi A5, year by year: known faults from UK buying guides, the parts flagged at MOT more than on other cars (from 373,852 MOTs done during 2023–2025), and what to check before you buy one.

The 2025 Audi A5

Cars registered in 2025 haven’t had their first MOT yet (it’s due at 3 years old), so there are no MOT results to show. There are no known faults on record for this year in the UK buying guides we use, so the rest of this page covers the Audi A5 as a whole.

What to check on a 2025 car
  • Warranty left

    Ask for the date it was first registered and check how much of the maker’s warranty is left, and that it transfers to you. Electric and hybrid batteries usually have a longer, separate warranty.

  • Servicing

    Servicing on time with the maker’s schedule keeps the warranty valid. Ask for the service book or the dealer’s digital record.

  • Finance

    Nearly new cars are often still on finance. A history check shows outstanding finance, and whether it has been written off or stolen.

  • Recalls

    Ask whether any recall work has been done, and check the reg on GOV.UK’s free recall checker.

  • Logbook (V5C)

    The name and address should match the seller, and the VIN on the V5C should match the car.

Questions to ask the seller before buying an Audi A5

Ask before you travel to see it. A seller who knows the car will have answers, and receipts.

  1. How much oil does it use between services?
  2. Has the gearbox had any work, and has its oil been changed on time?
  3. Have all the recalls been done? Can an Audi dealer confirm from the VIN?
  4. Any recent work on the suspension arm bushes and joints? (Flagged at MOT 3.3× as often on the Audi A5 as on other cars the same age.)
  5. Any recent work on the coil springs? (Flagged at MOT 47× as often on the Audi A5 as on other cars the same age.)
  6. Any recent work on the shock absorbers? (Flagged at MOT 2.8× as often on the Audi A5 as on other cars the same age.)

Looking at an Audi A5?
