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 BMW 5 Series 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.
Suspension
Two faults. The strongest is the suspension arm ball joint (rear): 60 times as often as on similar cars.
Figures below are measured across the 2,003 of 2,007 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.
Suspension arm ball joint (rear)
What it means
A suspension arm ball joint is failed under the general suspension pin, bush or joint wording. Excessively worn is Major, and 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 89 first tests, 39 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.
Brakes
Two faults. The strongest is the flexible brake hoses (rear): 8.5 times as often as on similar cars.
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.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 148 first tests, 2.8 times as often as on similar cars.
Handbrake lever
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 21 first tests, 4.6 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.
Tyres
One wear pattern: tyre tread depth (rear), 2.5 times as often as on similar cars.
Tyre tread depth (rear)
What it means
Only primary grooves count when tread depth is assessed: those holding the wear indicators, or cut as deep as those when new. Shallower secondary grooves are ignored. Tread depth below the minimum for the vehicle is Dangerous, and so is a pattern not visible over the whole tread, but that second row applies only to vehicles that need the lower minimum.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Road wheels
One fault: wheel fixings (front), 2.3 times as often as on similar cars.
Wheel fixings (front)
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Steering
One fault: track rod end (front), 2.1 times as often as on similar cars.
Track rod end (front)
What it means
A steering ball joint with excessive wear or free play is Major, and one worn to the extent there is a serious risk of detachment is graded Dangerous. A dust cover that is damaged but still keeps dirt out is Minor, and one missing or no longer keeping dirt out is Major. Testers must tell wear from a joint's built-in clearance or spring loading.
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.

MOT pass rates
How first tests ended, and how the pass rates are counted.
- Passed first time
- 69in 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
- 26in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 69.3% of 6,531 first tests (2025): only cars that passed first time count. Official-style pass 74.4%: cars fixed at the test station also count as a pass. The 5 fixed and the 26 not fixed make the 31 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.

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 BMW 5 Series.
Of 2007 BMW 5 Series vehicles with under 120,000 miles, 74 in every 100 passed their 2025 MOT first time. With 196,000 miles or more, 66 in every 100 did.
Petrol or diesel?
| Typical mileage | Passed first time, as tested | Passed first time, same mileage | |
|---|---|---|---|
| Diesel | 162,597 miles | 68 | 69 |
| Petrol | 117,255 miles | 75 | 72 |
Figures are in every 100 first tests. Petrol cars look better on the raw figures only because diesel cars have done more miles (typically 162,597 against 117,255). 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 120,000 | 146,000–169,000 | 196,000 and over | |
|---|---|---|---|
| Track rod end (front) | 2.3 | 3.1 | 3.3 |
| Handbrake efficiency below minimum (roller test) | 1.5 | 3.4 | 4.1 |
| Tyre condition (rear) | 3.1 | 3.3 | 3.6 |
| Anti-roll bar linkage ball joint dust cover (front) | 4.1 | 2.8 | 2.3 |
| Tyre tread depth (rear) | 1.7 | 2.7 | 3.9 |
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.
