The 2003 Mazda Eunos MOT pass rate is 74.3% of its MOT tests — 1.7 points ahead of what its age and mileage predict. Brakes is the biggest single reason it fails, at 21.6% of what testers record.

Expert verdict
Emissions & leaks make up 16.1% of everything recorded on the 2003 Mazda Eunos, against 5.5% nationally — 10.6 points above. Brakes are still the single largest share at 21.6%, but at 20.9% nationally that one is ordinary. A smoky diesel or a leaking joint fails on emissions more often than on wear, so ask for a recent emissions printout.

Cars of this age and mileage average 72.6%, so this figure is 1.7 points ahead of what its age and mileage predict. On a first attempt, before any retests, the figure drops to 69.2%. The median 2003 Mazda Eunos in this dataset had covered 109,418 mi.
Pass rates also shift with the test month: tests recorded October–March passed 73.5% of the time, April–September 74.7%.
The single most recorded failure item is "Ball joint dust cover severely deteriorated", noted on 6.08% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

Regions come from the postcode area recorded at the test station. Areas on region borders are assigned to the region with the majority of their population.
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
Check the suspension joints 6.1% of tests
“ball joint dust cover severely deteriorated”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
Check the lights 4.2% of tests
“rear fog lamp not working”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Check the steering 3.2% of tests
“steering rack gaiter missing or no longer prevents the ingress of dirt”
With the wheels straight, rock the steering wheel gently with the engine off — more than about an inch of free play before the wheels move is worth investigating. Split rack gaiters are cheap to replace and commonly recorded.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
Across the 10 items that are recorded most often on this model, the average repair comes to £29–£76 — and 30% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 378 MOT tests on this vehicle. They exclude diagnostics, retest fees and garage labour where the part is a DIY fit, and they are not figures from the DVSA dataset. Older and higher-mileage examples cost more than the average.

8 model years on record, from 2000 to 2007. Across them the pass rate runs from 70.8% to 78.0% — a spread of 7.2 points. The bar under each year is the item that failed it most often.
Colour is the pass rate on a fixed scale, so a block means the same thing on any model. Each year links to its own page with the full fault breakdown.
The raw pass rate mostly measures age. The year comparison adds the like-for-like figure, the mileage bands and the repair bill.
Closest pass rates among 2003 cars with at least 2,000 tests, so a small sample cannot flatter itself into the list. See the full rankings: best and worst MOT pass rates.

Severity is as recorded: Major and Dangerous fail the test outright; Minor and Advisory do not. Costs are estimates from typical UK parts prices — see how they are built.
Advisories are the early warnings — the same parts a year or two before they fail. Reading them is how you tell a car that has been maintained from one that has been patched.

|---|---|---|---|
| Engine oil leaks leaking excessively from engine Noise, emissions and leaks | Advisory | 27.5% | £200–700 |
| Rigid brake pipes excessively corroded Brakes | Advisory | 16.7% | £80–180 |
| Tread depth below requirements of 1.6mm Tyres | Advisory | 12.2% | £45–95 |

74.3% of the 378 2003 Mazda Eunos tests in this dataset passed, against a national average of 72.6% for cars first used in 2003. First-attempt pass rate: 69.2%.
The three most recorded items are ball joint dust cover severely deteriorated (6.08%), rear fog lamp not working (4.23%), registration plate lamp(s) inoperative in the case of multiple lamps or light sources (4.23%). Percentages are the share of tests on this vehicle that recorded the item.
Yes. Cars under 30,000 miles passed 80.0% of the time, falling to 74.1% for those over 120,000 miles. The median 2003 Mazda Eunos in this dataset had covered 109,418 mi.
Tests recorded in the winter months (October–March) passed 73.5% of the time; summer months (April–September) passed 74.7%. Brakes, tyres and lights are tested harder in bad weather, but the difference is small on most models.
