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 2006 Vauxhall Meriva 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.
Noise, emissions and leaks
One fault: engine oil leaks, 4.0 times as often as on similar cars.
Figures below are measured across the 1,443 of 1,464 failed first attempts (98.6%) 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.
Engine oil leaks
What it means
Leaks of engine coolant, screen wash and the fluid used for selective catalyst reduction are not reasons for failure. Excessive leaking from the engine that is likely to harm the environment or to pose a safety risk to other road users is Major. Continuous leaking likely to pose a serious risk to road safety is graded Dangerous.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Brakes
Four faults and two wear patterns. The strongest is the rigid brake pipes (front): 3.4 times as often as on similar cars.
Rigid brake pipes (front)
What it means
Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 203 first tests, 2.5 times as often as on similar cars.
Rigid brake pipes (rear)
What it means
Chafing, corrosion or damage to a rigid brake pipe justifies rejection once its wall thickness is reduced by a set amount, although DVSA accepts this is not easy to determine. If a tester is not sure, the benefit of the doubt applies. A leaking pipe or connection is graded Dangerous on a hydraulic system and Major on an air system.
Also noted as an advisory
Testers also noted it as an advisory, worn but not yet failing, on 289 first tests, 2.4 times as often as on similar cars.
Brake discs (rear)
What it means
A brake disc or drum must be significantly worn before it is rejected, and being worn below the manufacturer's recommended limits is not a reason in itself. Significantly and obviously worn is Major, as is contamination with oil or grease. A disc or drum that is fractured, insecure, seriously weakened or missing is graded Dangerous.
Brake performance not tested
What it means
A brake performance test recorded as unable to be tested is Major. DVSA says the result must only be used where it becomes apparent during the test that the item cannot be tested, and this could not have been identified before starting. The reason has to go in the additional information box.
Flexible brake hoses (front)
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.
Brake pads (rear)
What it means
A pad worn down to its wear indicator, or contaminated with oil or grease, is Major. A pad worn below the set thickness limit, missing or incorrectly mounted is Dangerous. The manual treats an illuminated brake wear indicator as no reason for failure, although DVSA also lists an illuminated indicator as a Major row.
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), 2.7 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.
Lamps and electrical
One fault: individual sidelight or tail light (rear), 2.4 times as often as on similar cars.
Individual sidelight or tail light (rear)
What it means
A position lamp showing red light to the front or white light to the rear is Major. Rear lamps must show a steady red light, and front ones can show white, predominantly white with a blue tinge, or yellow if combined in a yellow headlamp. With a multiple light source, up to half not working is Minor and more than half is Major.
Data: UK MOT open data, 2025. Compared with cars of the same age and mileage.
Suspension
Three faults. The strongest is the shock absorbers (rear): 2.4 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 130 first tests, 2.8 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 232 first tests, 4.9 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.
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.
Exhaust system (rear)
Track rod end (front)
Non-component advisories (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
- 47in every 100
- Passed on the first test.
- Fixed at the station
- 8in every 100
- Failed, then fixed at the test station the same day.
- Failed
- 45in every 100
- Did not pass, and were not fixed at the test station.
First-attempt pass 46.8% of 2,751 first tests (2025): only cars that passed first time count. Official-style pass 54.8%: cars fixed at the test station also count as a pass. The 8 fixed and the 45 not fixed make the 53 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, 46 in every 100 passed first time.

If you are buying one
What this year's MOT record means for the decision in front of you.
Mileage matters most on a 2006 Meriva.
Of 2006 Meriva vehicles with under 61,000 miles, 56 in every 100 passed their 2025 MOT first time. With 115,000 miles or more, 41 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 61,000 | 80,000–95,000 | 115,000 and over | |
|---|---|---|---|
| Drive shaft joints and boots (front) | 6.2 | 10.1 | 8.1 |
| Rigid brake pipes (rear) | 3.8 | 7.0 | 6.1 |
| Petrol engine warning light | 3.7 | 5.3 | 4.4 |
| Individual sidelight or tail light (front) | 1.3 | 5.7 | 5.9 |
| Windscreen washers | 4.0 | 5.7 | 4.4 |

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.
