How we count this. Data: UK MOT open data, 2025. Only Class 4 cars on their first MOT of the year are counted. A car that fails and is fixed at the test station still counts as a fail in the first-attempt rate. These are raw results, not adjusted for age, mileage, or peer mix. The MOT does not test engine or gearbox internals.
These are patterns across 2022 Audi Q5 vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Noise, emissions and leaks
Two faults. The strongest is the petrol engine warning light: 5.3 times as often as on similar cars.
Figures below are measured across the 682 failed first attempts in 2025 that had a mileage recorded, which allows a like-for-like comparison.
We only list faults with at least 20 failures and a rate of about 2.0 times that of similar cars, which keeps one-off results out of the list.
Petrol engine warning light
What it means
The malfunction indicator lamp (MIL) on a petrol engine is a Major failure when it is illuminated indicating a malfunction. The detail line DVSA gives for the same row also names an inoperative lamp. The test covers only certain petrol vehicles, depending on their age, size and fuel type.
Diesel engine warning light
What it means
An engine malfunction indicator lamp that is illuminated to show a malfunction is graded Major on a diesel, but only on the diesels the test covers, which depends on the vehicle type and when it was first used. DVSA lists it under exhaust emissions for compression ignition engines, and the detail line for the row also names an inoperative lamp.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Seat belts and restraints
One fault: airbag warning light, 3.9 times as often as on similar cars.
Airbag warning light
What it means
The airbag warning lamp (SRS MIL in DVSA's wording) is failed only if it indicates a system malfunction, which is Major. A lamp lit to show the passenger airbag is disabled is not to be regarded as a defect. Dashboard messages are not a defect in their own right, though they can help the tester confirm a malfunction.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Number plates and VIN
Two faults. The strongest is the number plates (rear): 2.9 times as often as on similar cars.
Number plates (rear)
What it means
A number plate that is missing, illegible, showing an incorrect registration or so insecure that it is likely to fall off is Major. Testers do not measure the characters or their spacing and reject them only if they are obviously incorrect. Delamination and the position of fixing screws or bolts get particular attention, as they can prevent number plate recognition cameras identifying the vehicle.
Number plates (front)
What it means
A number plate that is missing, illegible, showing an incorrect registration or so insecure that it is likely to fall off is Major. Testers do not measure the characters or their spacing and reject them only if they are obviously incorrect. Delamination and the position of fixing screws or bolts get particular attention, as they can prevent number plate recognition cameras identifying the vehicle.

MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 93in every 100
- Passed on the first test.
- Fixed at the station
- 1in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 6in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 92.5% of 9,151 first tests (2025): only cars that passed first time count. Official-style pass 93.7%: cars fixed at the test station also count as a pass. The 1 fixed and the 6 not fixed make the 7 in every 100 that did not pass first time.
By fuel type
Figures are in every 100 first tests. Cars with more miles usually fail more often, so the same-mileage figure gives every fuel the mileage mix of all the cars in this year.
Same model, other years
Passed first time in every 100, all tested in 2025.
Newer cars are younger, so look for a jump rather than the climb.

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage makes a modest difference on a 2022 Audi Q5.
Of 2022 Audi Q5 vehicles with under 19,000 miles, 95 in every 100 passed their 2025 MOT first time. With 38,000 miles or more, 91 in every 100 did.
What to check at your mileage
How often each fault turned up on a failed first test, by the car's mileage. Read it as: what is likely to need looking at on a car like the one in front of you.
| Under 19,000 | 25,000–30,000 | 38,000 and over | |
|---|---|---|---|
| Tyre condition (rear) | 0.9 | 1.6 | 2.4 |
| Tyre tread depth (front) | 0.8 | 0.5 | 1.5 |
Faults per 100 first tests, by the car's mileage at the test.
When a car fails
of failed cars had one item to fix.
of failed cars had three or more items to fix.
of all first tests had a defect the tester marked dangerous (unsafe to drive away).
Every figure here is a first-attempt MOT rate from DVSA open data for this model line, for cars of this model year tested in 2025. Each mileage band holds a fifth of the tests. MOTs do not test engine or gearbox internals, so this is a pre-purchase checklist, not a full reliability score.
FAQs
Short answers about how to read this model-year guide.
About this data
How this page is built and what it can (and can't) say.
These figures come from UK MOT open data for this model year. We surface common failure patterns against similar cars, not a full reliability score, and not a pass/fail verdict on any individual vehicle.
What we include
UK Class 4 cars only. Normal MOT tests (not retests); first test per vehicle per calendar year; results pass, PRS, or fail.
Same-day repairs
PRS means the car failed items that were fixed at the test station and then passed the same day. We count PRS as a first-attempt fail in headline rates so same-day repairs do not hide problems.
How we compare
We compare this model year with other Class 4 cars of similar age and mileage in the same test year. This model family is left out of the peer group so the car is not measured against itself.
What this does not cover
- MOTs do not cover engine internals, gearboxes, or many electronics; this is not a full reliability score.
- Common faults come from MOT defect stats, not manufacturer TSBs or recalls.
- Age and mileage matching reduces, but does not remove, differences in how cars were used and maintained.
- If the data for a car is too thin to say anything useful, we say so rather than guess.
