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 2005 Volkswagen Touran 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 electronic stability control: 4.1 times as often as on similar cars.
Figures below are measured across the 911 of 933 failed first attempts (97.6%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like. 2.4% of failures are excluded because no mileage was recorded, so treat these shares as indicative for this model year.
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.
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.
Flexible brake hoses (rear)
What it means
Testers reject a flexible brake hose for being excessively damaged or chafed only if it is severe enough to expose the reinforcement. Slight damage, chafing or twisting is graded Minor. A leak is graded Dangerous on a hydraulic braking system and Major on an air system, and a hose damaged and likely to fail is also Dangerous.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Noise, emissions and leaks
Two faults. The strongest is the diesel engine warning light: 3.8 times as often as on similar cars.
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.
Diesel emissions test (pre-reg turbo rules before 01/07/2008)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Seat belts and restraints
One fault: seat belt condition (rear), 2.8 times as often as on similar cars.
Seat belt condition (rear)
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 65 first tests, 13 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.
Suspension
Three faults. The strongest is the suspension arm pins and bushes (front): 2.8 times as often as on similar cars.
Suspension arm pins and bushes (front)
What it means
Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 201 first tests, 2.4 times as often as on similar cars.
Suspension arm pins and bushes (rear)
What it means
Pins and bushes on suspension arms fail as Major when they are excessively worn. They are graded Dangerous when likely to become detached. DVSA uses the same wording for a suspension joint.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 89 first tests, 3.0 times as often as on similar cars.
Anti-roll bar ball joint dust cover (front)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage. Advisories count notes recorded on failed first tests only.
Lamps and electrical
One fault: individual direction indicators (rear), 2.1 times as often as on similar cars.
Individual direction indicators (rear)
What it means
Direction indicators must be amber, though vehicles first used before a set date may have white at the front and red at the rear when the indicators are combined with stop or position lamps, and sequential or dynamic ones are not a reason to fail. A lamp that is missing, inoperative or has more than half of a multiple light source not functioning is graded Major. A flashing rate outside the permitted range is graded Minor.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 25 first tests, 2.1 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.
Body and structure
One fault: drive shaft joints and boots (front), 2.0 times as often as on similar cars.
Drive shaft joints and boots (front)
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.
Shock absorbers (front)
Suspension sub-frame (rear)
Individual direction indicators (front)
Suspension arm (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
- 53in every 100
- Passed on the first test.
- Fixed at the station
- 9in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 38in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 53.4% of 2,004 first tests (2025): only cars that passed first time count. Official-style pass 61.8%: cars fixed at the test station also count as a pass. The 9 fixed and the 38 not fixed make the 47 in every 100 that did not pass first time.
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, 52 in every 100 passed first time.

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.
