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 2012 Volkswagen Scirocco vehicles in 2025, not a prediction that any one car will have them. Faults are grouped by part of the car. A wear pattern follows age and use more than the way the car was built. They come from MOT defect codes, not manufacturer bulletins, recalls or a diagnosis of any one car.
Lamps and electrical
One fault: headlight levelling device (front), 19 times as often as on similar cars.
Figures below are measured across the 1,423 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.
Headlight levelling device (front)
What it means
A headlamp levelling device that is inoperative is graded Major, and so is a manual levelling device that cannot be operated from the driver's seat. Vehicles with high intensity discharge or LED dipped beam headlamps may have a self-levelling system, and if fitted it must work. Where it is not easy to tell, testers give the benefit of the doubt, and motor caravans are not checked.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Suspension
Three faults. The strongest is the suspension arm (rear): 4.2 times as often as on similar cars.
Suspension arm (rear)
What it means
A missing bump stop rubber is not a reason to fail a suspension arm. A component that is fractured, missing or likely to fail is graded Dangerous, and one excessively damaged or corroded is Major. On some vehicles, some highly stressed parts are thin pressed steel, and many of those have hollow box sections or up-facing areas that can collect road dirt and salt, so they get special attention.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 105 first tests, 3.5 times as often as on similar cars.
Anti-roll bar linkage ball joints (rear)
What it means
Excessive wear on an anti-roll bar linkage ball joint is Major. A joint likely to become detached is graded Dangerous.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 74 first tests, 5.6 times as often as on similar cars.
Anti-roll bar linkage ball joint dust cover (front)
What it means
A suspension joint dust cover that is severely deteriorated is Minor. It becomes Major once it is missing or no longer prevents the ingress of dirt, so what matters is whether it still keeps dirt out. DVSA words this for any suspension joint dust cover, and files it here under anti-roll bars.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Tyres
One wear pattern: tyre pressure monitoring system, 4.1 times as often as on similar cars.
Tyre pressure monitoring system
What it means
A tyre pressure monitoring system that is obviously inoperative is graded Major, and so is one listed as malfunctioning or obviously inoperative. The Minor row uses the word malfunctioning too, but its detail is a warning lamp indicating a fault, and it also covers a tyre that is obviously under-inflated.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Brakes
One fault: electronic stability control, 2.1 times as often as on similar cars.
Electronic stability control
What it means
An ESC warning lamp is failed only when the tester is certain it indicates an ESC malfunction, because the lamp takes various forms and the owner's handbook may need checking. The system is also called ESP, VDC or DSC, among many other names. Every failure row is Major, covering the lamp, wheel speed sensors, wiring, other components and the switch.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Advisories
Other things testers noted as worn or close to failing, more often than on similar cars.
An advisory is a note from the tester about something that has not failed yet. It is an early warning, not a fail. Advisories for the faults above are shown with those faults.
Headlight (front)
Wheel condition (rear)
Data: UK MOT open data, 2025. Counts cover advisories recorded on failed first tests only, compared with cars of the same age and mileage.
MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 65in every 100
- Passed on the first test.
- Fixed at the station
- 5in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 30in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 64.6% of 4,016 first tests (2025): only cars that passed first time count. Official-style pass 69.6%: cars fixed at the test station also count as a pass. The 5 fixed and the 30 not fixed make the 35 in every 100 that did not pass first time.
Petrol and diesel
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. A year earlier (2024), when these cars were a year younger, 66 in every 100 passed first time.
| Year | Passed first time | First tests |
|---|---|---|
| 2008 | 60 in every 100 | 814 |
| 2009 | 60 in every 100 | 4,559 |
| 2010 | 61 in every 100 | 5,567 |
| 2011 | 62 in every 100 | 5,434 |
| 2012 This car | 65 in every 100 | 4,016 |
| 2013 | 66 in every 100 | 4,133 |
| 2014 | 68 in every 100 | 3,519 |
| 2015 | 74 in every 100 | 5,153 |
| 2016 | 78 in every 100 | 5,022 |
| 2017 | 80 in every 100 | 4,427 |
| 2018 | 84 in every 100 | 614 |
If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2012 Scirocco.
Of 2012 Scirocco vehicles with under 82,000 miles, 73 in every 100 passed their 2025 MOT first time. With 138,000 miles or more, 59 in every 100 did.
Petrol or diesel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Diesel | 117,254 miles | 63 | 64 |
| Petrol | 90,058 miles | 68 | 66 |
Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 117,254 against 90,058). At the same mileage there is no clear difference between the two.
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 82,000 | 101,000–117,000 | 138,000 and over | |
|---|---|---|---|
| Individual sidelight or tail light (front) | 2.3 | 4.7 | 5.1 |
| Tyre condition (front) | 3.8 | 4.0 | 3.4 |
| Coil spring (front) | 3.8 | 3.3 | 4.1 |
| Anti-roll bar linkage ball joint dust cover (front) | 1.5 | 4.7 | 3.6 |
| Handbrake efficiency below minimum (roller test) | 0.8 | 2.9 | 4.0 |
Faults per 100 first tests, by the car's mileage at the test.

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.

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.
