BMW 218
The BMW 218 MOT pass rate for cars first registered 2016–2021 is 87% across 198,901 official UK DVSA tests. 87% of BMW 218 MOT tests in this age band end in a pass — but 218,941 defect notes sit behind that headline across 198,901 recorded tests. Most of those notes trace to upkeep gaps rather than inherent mechanical weakness, which matters when you are judging a private sale or dealer example on its own merits.
Unlike a registration check, this report analyses how thousands of similar BMW 218 models have performed at MOT over time — not just one vehicle.

Most common owner-maintenance faults
DVSA wording grouped as owner maintenance for this model and age band.
- 1
Tyre worn close to legal limit/worn on edge
55,503 notes5.2.3 (e)What it means, why it happens, what to check
What it means
- Tread is close to (or at) the legal minimum, or wear is concentrated on an edge. That often points to alignment, pressure or suspension issues as well as simple age.
Why it happens
- Under-inflation, poor alignment, aggressive driving or simply delayed replacement push tread below a safe/legal profile.
Buyer tip
- Measure tread across the full width, check tyre age (DOT date) and look for uneven inner-edge wear.
Severity
- Usually maintenance related
- 2
Headlamp aim too low
3,549 notes4.1.2 (a)What it means, why it happens, what to check
What it means
- This MOT defect usually indicates incorrect headlamp alignment following adjustment, suspension movement or repair work.
Why it happens
- Aim drifts after suspension work, bumper repairs, bulb changes or simply from road vibration over time.
Buyer tip
- Check beam alignment during inspection and ask whether the lamps were aimed after any recent suspension or bodywork.
Severity
- Usually maintenance related
- 3
Shock absorbers has light misting of oil
2,755 notes5.3.2 (b)What it means, why it happens, what to check
What it means
- A damper mounting bush is worn, which can cause knocks, vague handling and accelerated tyre wear.
Why it happens
- Rubber bushes harden and tear with age, road salt and repeated suspension movement.
Buyer tip
- Listen for clunks over speed bumps and have a mechanic check top mounts and lower bushes.
Severity
- Usually maintenance related
- 4
Windscreen washer not working
2,442 notes3.5 (a)What it means, why it happens, what to check
What it means
- Washer jets are not delivering fluid. Testers need a clear screen; empty reservoirs, blocked jets or failed pumps are common.
Why it happens
- Empty bottles, frozen/blocked jets, split pipes or a failed pump stop fluid reaching the screen.
Buyer tip
- Top up fluid, test the jets on the driveway, and check for cracked bottles or split pipes in the engine bay.
Severity
- Usually maintenance related
- 5
Headlamp aim projected beam image is obviously incorrect
1,375 notes4.1.2 (c)What it means, why it happens, what to check
What it means
- This MOT defect usually indicates incorrect headlamp alignment following adjustment, suspension movement or repair work.
Why it happens
- Aim drifts after suspension work, bumper repairs, bulb changes or simply from road vibration over time.
Buyer tip
- Check beam alignment during inspection and ask whether the lamps were aimed after any recent suspension or bodywork.
Severity
- Usually maintenance related
- 6
Tyre pressure monitoring system malfunctioning or obviously inoperative
722 notes5.2.3 (h)What it means, why it happens, what to check
What it means
- The tyre pressure monitoring system is reporting a fault or is clearly not working, so you may not get a dashboard warning of under-inflation.
Why it happens
- Flat battery sensors after tyre changes, damaged valves or control-module faults are common.

- Confirm whether sensors need replacing after recent tyre or wheel work, and check pressures manually anyway.
Severity
- Usually maintenance related
- 7
Seat belt buckle slightly damaged
317 notes7.1.2 (d)What it means, why it happens, what to check
What it means
- This wording appears on DVSA MOT records for this model. It flags a tester-observed defect or advisory that can affect safety, legality or a future pass.
Why it happens
- These issues often build up when routine checks are skipped between services — tyres, lamps and washers are typical examples.
Buyer tip
- Ask the seller for invoices covering this item, and have an independent inspector confirm whether it is still present.
Severity
- Usually maintenance related
- 8
Headlamp aim not tested
187 notes4.1.2 (b)What it means, why it happens, what to check
What it means
- This MOT defect usually indicates incorrect headlamp alignment following adjustment, suspension movement or repair work.
Why it happens

BMW 218 research summary
Carmotiq groups 218,941 MOT defect notes from the BMW 218 fleet into four buckets. Owner neglect accounts for 148,812 notes — tyres alone contribute 55,503 — while wear-and-tear items add 29,738, systemic faults 5,528, and 34,863 fall into other categories. Headlamp aim issues, shock absorber oil misting, and non-working windscreen washers also rank highly among upkeep-related items, suggesting many failures are visible on a basic pre-purchase walkaround.
For a buyer, the split is the practical takeaway: an 87% pass rate is solid, yet the fault ledger is dominated by items a careful inspection can catch before money changes hands. Systemic notes are a smaller share but include engine MIL faults and corroded rear brake pipes worth probing on a ramp. Use this alongside a physical inspection, a GOV.UK MOT lookup on your chosen car, and any history check — not as a substitute for any of them.

How we classify MOT faults
We group recorded DVSA defect wording into four research categories to help identify whether issues are more likely to reflect routine maintenance, expected wear, recurring model patterns or miscellaneous inspection outcomes.
- Owner maintenance
- Defects often linked to day-to-day upkeep — tyres, lamps, washers and other items a careful owner can usually prevent or fix promptly.
- Wear & tear
- Age- and mileage-related deterioration that accumulates with normal use, even when a car has been looked after.
- Systemic
- Recurring wording and patterns across the model fleet that may point to design, component or known-model tendencies rather than one careless owner.
- Other
- Inspection outcomes that do not sit cleanly in the three groups above, including mixed or less classifiable defect notes.

Buying a used BMW 218: practical MOT checks
- 1Inspect all four tyres for edge wear and tread depth close to the 1.6 mm legal minimum — this is the single highest-volume MOT note on the BMW 218 fleet.
- 2Check headlamp aim on a wall or ask the seller when bulbs were last adjusted, because aim faults appear thousands of times in the records.
- 3Look underneath for light oil misting on shock absorbers and confirm the windscreen washer sprays correctly on both sides.
- 4With the ignition on, verify the engine management light illuminates at start-up and goes out — inoperative or stuck-on MIL notes are among the leading systemic items.
