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 2007 Volkswagen Passat 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.
Brakes
One fault: electronic parking brake, 18 times as often as on similar cars.
Figures below are measured across the 2,379 of 2,383 failed first attempts (99.8%) that recorded an odometer reading in 2025. Mileage is needed to compare like with like.
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 parking brake
What it means
An electronic parking brake is applied electronically but must still be maintained in operation by direct mechanical means. It may apply automatically in certain conditions, such as when the ignition is switched off or when the driver's door is opened. A control that is missing, defective or inoperative is Major, and so is a malfunction warning.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Body and structure
Three faults. The strongest is the driver's door condition: 16 times as often as on similar cars.
Driver's door condition
What it means
Doors without handles by original design or specialist modification are not a defect so long as the door latches securely closed and can still be opened using the relevant control, such as a button or a fob. A door likely to open inadvertently or not remain closed is Major on a sliding door and graded Dangerous on a hinged one.
Body panel (front)
Drive shaft joints and boots (front)
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 emissions test (pre-reg turbo rules before 01/07/2008): 3.0 times as often as on similar cars.
Diesel emissions test (pre-reg turbo rules before 01/07/2008)
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.
Suspension
Three faults. The strongest is the anti-roll bar linkage ball joints (rear): 2.7 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 126 first tests, 3.9 times as often as on similar cars.
Coil spring (rear)
What it means
A missing bump stop rubber is not a reason to fail a coil spring. When the vehicle is jacked and lowered, a spring that does not correctly locate as the suspension returns to its normal running position is rejected as insecurely attached. A missing spring is Major, and graded Dangerous where directional control is affected.
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 269 first tests, 3.5 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.
Lamps and electrical
One fault: side repeater indicators, 2.1 times as often as on similar cars.
Side repeater indicators
What it means
Sequential or dynamic direction indicators are not a reason to fail. Where a side repeater is required, it is allowed to be part of the front direction indicator if it has a marked wraparound lens, or an amber light coming through the front lens when viewed from a set distance to the side of the rear bumper. A lens defect with no effect on the emitted light is Minor, and one that adversely affects the light is Major.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Tyres
One wear pattern: tyre condition (rear), 2.0 times as often as on similar cars.
Tyre condition (rear)
What it means
Exposed or damaged ply or cords are graded Dangerous. A cut in excess of the requirements and deep enough to reach the ply or cords is Major, and testers may open the cut with a blunt instrument to check its depth. A tyre contacting the vehicle through flexing or suspension movement is not a defect; fouling fails only at the time of test.
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.
Suspension sub-frame (rear)
Suspension arm (rear)
Suspension arm pins and bushes (front)
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
- 59in every 100
- Passed on the first test.
- Fixed at the station
- 6in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 35in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 58.6% of 5,753 first tests (2025): only cars that passed first time count. Official-style pass 65.4%: cars fixed at the test station also count as a pass. The 6 fixed and the 35 not fixed make the 41 in every 100 that did not pass first time.
Petrol and diesel
Figures are in every 100 first tests.
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 2007 Passat.
Of 2007 Passat vehicles with under 115,000 miles, 62 in every 100 passed their 2025 MOT first time. With 187,000 miles or more, 58 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 115,000 | 141,000–161,000 | 187,000 and over | |
|---|---|---|---|
| Drive shaft joints and boots (front) | 6.9 | 7.4 | 6.0 |
| Tyre condition (rear) | 3.4 | 4.9 | 5.6 |
| Coil spring (rear) | 4.7 | 3.3 | 2.5 |
| Headlight aim | 2.4 | 3.7 | 4.8 |
| Anti-roll bar linkage ball joint dust cover (front) | 3.0 | 2.7 | 3.1 |

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.

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.
