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 2017 Volkswagen Scirocco 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.
Brakes
Two faults. The strongest is the anti-lock braking system (ABS): 6.1 times as often as on similar cars.
Figures below are measured across the 877 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.
Anti-lock braking system (ABS)
What it means
ABS is failed as removed only where it has obviously been removed, because not every vehicle in the age range where removal is not permitted has ABS. A warning lamp that does not light or shows an ABS fault is Major, as is a missing or excessively damaged wheel speed sensor. Every failure row for this component is Major.
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.
Suspension
Two faults. The strongest is the shock absorbers (rear): 3.2 times as often as on similar cars.
Shock absorbers (rear)
What it means
Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 38 first tests, 2.4 times as often as on similar cars.
Shock absorbers (front)
What it means
Slight seepage that leaves a film of fluid on a shock absorber does not fail it. Severe leakage, or damage so that it does not function, is Major. A shock absorber missing or likely to become detached is graded Dangerous, though a missing one is only rejected if shock absorbers were fitted as standard.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 62 first tests, 2.6 times as often as on similar cars.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
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.

Wheel condition (rear)
Coil spring (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
- 80in every 100
- Passed on the first test.
- Fixed at the station
- 3in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 17in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 80.2% of 4,427 first tests (2025): only cars that passed first time count. Official-style pass 82.6%: cars fixed at the test station also count as a pass. The 3 fixed and the 17 not fixed make the 20 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.
| 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 | 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 This car | 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 2017 Scirocco.
Of 2017 Scirocco vehicles with under 42,000 miles, 86 in every 100 passed their 2025 MOT first time. With 77,000 miles or more, 74 in every 100 did.
Petrol or diesel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Petrol | 54,916 miles | 82 | 82 |
| Diesel | 64,590 miles | 76 | 78 |
Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 64,590 against 54,916). 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 42,000 | 53,000–64,000 | 77,000 and over | |
|---|---|---|---|
| Tyre condition (front) | 2.2 | 3.4 | 4.3 |
| Tyre tread depth (front) | 1.0 | 2.2 | 2.3 |
| Brake pads (rear) | 1.2 | 1.5 | 1.6 |
| Coil spring (front) | 1.1 | 1.4 | 1.4 |
| Windscreen washers | 1.2 | 1.0 | 1.7 |
Faults per 100 first tests, by the car's mileage at the test.

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.

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.
