A pass rate is not a reliability score. The full Audi Q4 MOT record has the pass rate by age, every common failure and how the Q4 compares with similar cars.
Q4 fuel types
Most Audi Q4 cars tested in 2025 were electric. Electric cars need an MOT from three years old like any other car, and their tyres, brakes, suspension and lights are tested the same way.
Where the Q4 fails its MOT
Where Audi Q4 cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were condition has a cut in excess of the requirements deep enough to reach the ply or cords (29.7%), condition has ply or cords exposed (23.2%) and tread depth below requirements of 1.6mm (11.9%). See every common Q4 MOT failure.
These are DVSA failure records across every Audi Q4 that failed, not a claim that every Q4 has these problems.
What should you check when buying a used Q4?
The areas above, most common first, and what an MOT tester looks at in each.
1
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 72% of Q4 failure items.
2
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 10.6% of Q4 failure items.
3
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 7.3% of Q4 failure items.
4
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 3% of Q4 failure items.
5
Seat belts and supplementary restraint systems
Pull every seat belt out fully and check it latches and retracts, and that the airbag light goes out after starting. 2.3% of Q4 failure items.
None of this replaces the car's own record. Run a free MOT history check on the registration to see every test, advisory and recorded mileage for that car.
What the MOT record doesn't tell you
Knowing Audi Q4 failures cluster around tyres and lamps, reflectors and electrical equipment tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Audi Q4 FAQs
Is the Audi Q4 reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is an 87.7% first-time pass rate for the Audi Q4 across 10,681 tests in 2025, above the 72.3% average for all cars.
What should I check before buying a used Audi Q4?
On the car itself, start with the areas it most often fails on: tyres, lamps, reflectors and electrical equipment and visibility. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check an Audi Q4's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
