Cars of this age and mileage average 87.9%, so this figure is 3.7 points behind what its age and mileage predict. On a first attempt, before any retests, the figure drops to 81.4%. The median 2018 Vauxhall Adam in this dataset had covered 33,558 mi.
Pass rates also shift with the test month: tests recorded October–March passed 84.6% of the time, April–September 83.9%.
The single most recorded failure item is "Track rod end ball joint dust cover damaged or deteriorated, but preventing the ingress of dirt", noted on 5.03% of tests.
Figures count every completed test on this vehicle-year in the dataset, including retests. See methodology for the exact definition.

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 5.0% of tests
“track rod end ball joint dust cover damaged or 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 shock absorbers 3.5% of tests
“shock absorbers has a serious fluid leak”
Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.
Check the coil springs 2.5% of tests
“coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
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 £25–£61 — and 18% of those repairs are parts that cost under £30.
Estimates from typical UK parts prices, weighted by how often each item appears in 18,892 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 2012 to 2019. Across them the pass rate runs from 76.6% to 87.4% — a spread of 10.8 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 2018 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.

The three most recorded items are track rod end ball joint dust cover damaged or deteriorated, but preventing the ingress of dirt (5.03%), shock absorbers has a serious fluid leak (3.49%), coil spring fractured or broken (2.51%). Percentages are the share of tests on this vehicle that recorded the item.
Yes. Cars under 30,000 miles passed 88.5% of the time, falling to 78.6% for those over 120,000 miles. The median 2018 Vauxhall Adam in this dataset had covered 33,558 mi.
Tests recorded in the winter months (October–March) passed 84.6% of the time; summer months (April–September) passed 83.9%. Brakes, tyres and lights are tested harder in bad weather, but the difference is small on most models.
