Expert verdict
Tyres: 2.1× the national share
Tyres make up 41.2% of everything recorded on the 2018 BMW 1 Series, against 19.8% nationally — 21.4 points above. Check all four tyres yourself, including the inner shoulders, and look at the date stamp — a tyre can pass on tread and still be six years old.
- When it fails, it costs. Only 20% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2018 1 Series
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
Three checks worth doing on a 2018 1 Series
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 windscreen 2.3% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
Check the tyre tread 0.9% of tests
“tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
-
Check the brakes 0.9% of tests
“brake pads less than 1.5 mm thick”
Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
What it costs to get a 2018 1 Series through its MOT
Across the 10 items that are recorded most often on this model, the average repair comes to £42–£99 — and 20% of those repairs are parts that cost under £30.

What testers noted without failing the car
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.

|---|---|---|---|
| Tread depth below requirements of 1.6mm Tyres | Advisory | 14.9% | £45–95 |
| Brake pads less than 1.5 mm thick Brakes | Advisory | 9.9% | £18–45 |
