CARMOTIQ Model Research Report
BMW 218
2016–2021
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.

Key Findings
BMW 218 (2016–2021)
- The BMW 218 achieves an 87% MOT pass rate across 198,901 DVSA tests for cars first registered between 2016 and 2021.
- Owner-maintenance-related notes make up 148,812 of 218,941 total defects — roughly 68% of everything recorded for this model.
- Tyres worn close to the legal limit or worn on the edge appear 55,503 times, making them the highest-volume single fault by a wide margin.
- Systemic defect notes total 5,528, led by engine management indicator lamp faults (755 and 257 occurrences under separate test codes) and rear brake pipe corrosion (425).
- Defect volumes rise steadily from 2019 through 2025 as the fleet ages, with owner-neglect notes climbing from 6,177 in 2019 to 27,230 in 2025.
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.
What this doesn't tell you
This report describes model-level MOT trends, not the condition of any individual vehicle.
Two identical BMW 218 models can have very different maintenance histories.
Use this report to understand common patterns before inspecting a specific car.
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 — for example 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 that appear across the model fleet and 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.

Most Common Owner-Maintenance Faults
DVSA wording grouped as owner maintenance for this model and age band.
Tyre worn close to legal limit/worn on edge
- Recorded
- 55,503 MOT defect notes
- DVSA code
- 5.2.3 (e)
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
Headlamp aim too low
- Recorded
- 3,549 MOT defect notes
- DVSA code
- 4.1.2 (a)
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
Shock absorbers has light misting of oil
- Recorded
- 2,755 MOT defect notes
- DVSA code
- 5.3.2 (b)
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
Windscreen washer not working
- Recorded
- 2,442 MOT defect notes
- DVSA code
- 3.5 (a)
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
Headlamp aim projected beam image is obviously incorrect
- Recorded
- 1,375 MOT defect notes
- DVSA code
- 4.1.2 (c)
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
Tyre pressure monitoring system malfunctioning or obviously inoperative
- Recorded
- 722 MOT defect notes
- DVSA code
- 5.2.3 (h)
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.
Buyer tip
Confirm whether sensors need replacing after recent tyre or wheel work, and check pressures manually anyway.
Severity
Usually maintenance related
Seat belt buckle slightly damaged
- Recorded
- 317 MOT defect notes
- DVSA code
- 7.1.2 (d)
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
Headlamp aim not tested
- Recorded
- 187 MOT defect notes
- DVSA code
- 4.1.2 (b)
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
Most Common Wear & Tear Faults
DVSA wording grouped as wear and tear for this model and age band.
Exhaust emissions likely to be affected by an exhaust leak
- Recorded
- 7 MOT defect notes
- DVSA code
- 8.2.1.1 (b)
What it means
Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.
Why it happens
Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.
Buyer tip
Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.
Severity
Usually wear related
Exhaust emissions likely to be affected by an exhaust leak
- Recorded
- 4 MOT defect notes
- DVSA code
- 8.2.2.1 (b)
What it means
Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.
Why it happens
Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.
Buyer tip
Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.
Severity
Usually wear related
Shock absorbers has an excessively worn bush both
- Recorded
- 4 MOT defect notes
- DVSA code
- 5.3.2 (c)
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 wear related
Suspension component leaking oil filed bush
- Recorded
- 2 MOT defect notes
- DVSA code
- 5.3.5 (c)
What it means
A hydraulic suspension bush or related component is leaking fluid, which can change geometry and ride quality.
Why it happens
Hydraulic bush membranes split with age, leaking fluid and softening the mount.
Buyer tip
Look under the car for damp bushes and ask for specialist inspection on air/hydraulic systems.
Severity
Usually wear related
brake disc worn, pitted or scored, but not seriously weakened
- Recorded
- 1 MOT defect notes
- DVSA code
- 3.5.1i
What it means
A brake disc is contaminated, scored or otherwise not in a serviceable condition for consistent braking.
Why it happens
Worn pads, rust lip, oil contamination or delayed disc replacement leave an uneven braking surface.
Buyer tip
Check disc faces through the wheels and ask for pad/disc measurements if the car is due brakes soon.
Severity
Usually wear related
Registration plate deteriorated but not likely to be misread faded worn
- Recorded
- 1 MOT defect notes
- DVSA code
- 0.1 (b)
What it means
The number plate is cracked, deteriorated or hard to read. Plates must remain legible and securely fitted.
Why it happens
Age, stone chips, poor replacements or mounts that flex crack or fade plates.
Buyer tip
Budget for legal replacement plates; check fixing and any bike-rack or tow-bar obstruction.
Severity
Usually wear related
Service brake binding but not excessively unable to test wheel bearing
- Recorded
- 1 MOT defect notes
- DVSA code
- 1.2.1 (f)
What it means
Service brake performance could not be fully verified, or a brake is binding/fluctuating. That often points to worn discs, seized calipers or hub issues.
Why it happens
Seized caliper slides, worn discs or contaminated friction material upset brake balance.
Buyer tip
Insist on a road test and a proper brake inspection; unresolved binding can destroy pads and hubs.
Severity
Usually wear related
Brake performance unable to be tested pads worn below min thickness
- Recorded
- 1 MOT defect notes
- DVSA code
- 1.2.1 (g)
What it means
Service brake performance could not be fully verified, or a brake is binding/fluctuating. That often points to worn discs, seized calipers or hub issues.
Why it happens
Seized caliper slides, worn discs or contaminated friction material upset brake balance.
Buyer tip
Insist on a road test and a proper brake inspection; unresolved binding can destroy pads and hubs.
Severity
Usually wear related
Most Common Systemic Faults
DVSA wording grouped as systemic patterns for this model and age band.
Engine MIL inoperative or indicates a malfunction
- Recorded
- 755 MOT defect notes
- DVSA code
- 8.2.1.2 (h)
What it means
The engine management warning lamp is on or not working. Stored faults can affect emissions, drivability and future MOT results.
Why it happens
Sensors, emissions equipment or wiring faults store codes that illuminate the MIL.
Buyer tip
Ask for a diagnostic printout and proof that the underlying fault — not just the lamp — was fixed.
Severity
Often a recurring model pattern
Rear Brake pipe excessively corroded
- Recorded
- 425 MOT defect notes
- DVSA code
- 1.1.11 (c)
What it means

Why it happens
Road salt, stone chips and age corrode metal pipes, especially along the underbody.
Buyer tip
Inspect metal pipes along the underbody and near calipers; corroded pipes should be replaced before you rely on the car.
Severity
Often a recurring model pattern
Engine MIL inoperative or indicates a malfunction
- Recorded
- 257 MOT defect notes
- DVSA code
- 8.2.2.2 (g)
What it means
The engine management warning lamp is on or not working. Stored faults can affect emissions, drivability and future MOT results.
Why it happens
Sensors, emissions equipment or wiring faults store codes that illuminate the MIL.
Buyer tip
Ask for a diagnostic printout and proof that the underlying fault — not just the lamp — was fixed.
Severity
Often a recurring model pattern
Registration plate deteriorated but not likely to be misread cracked
- Recorded
- 36 MOT defect notes
- DVSA code
- 0.1 (b)
What it means
The number plate is cracked, deteriorated or hard to read. Plates must remain legible and securely fitted.
Why it happens
Age, stone chips, poor replacements or mounts that flex crack or fade plates.
Buyer tip
Budget for legal replacement plates; check fixing and any bike-rack or tow-bar obstruction.
Severity
Often a recurring model pattern
Exhaust emissions - engine idle speed too high
- Recorded
- 31 MOT defect notes
- DVSA code
- 8.2.1.2 (e)
What it means
Emissions could not be completed cleanly, or a leak is likely to upset the reading. Common causes include exhaust leaks, misfires, DPF issues or an engine that will not idle correctly.
Why it happens
Leaks before the sample point, misfires, DPF problems or unstable idle prevent a valid emissions result.
Buyer tip
Listen for blow-by at joints, check for recent exhaust/DPF work, and avoid cars that need “easier” emissions excuses.
Severity
Often a recurring model pattern
Inner Road wheel fractured cracked
- Recorded
- 28 MOT defect notes
- DVSA code
- 5.2.2 (a)
What it means
A road wheel shows a crack or fracture. That is a structural safety issue, not a cosmetic mark.
Why it happens
Pothole impacts, corrosion or prior kerbing damage can crack alloy or steel wheels.
Buyer tip
Walk away or insist on replacement wheels and a re-test — do not treat this as a minor snag.
Severity
Often a recurring model pattern
Exhaust mounting defective bracket not affixed
- Recorded
- 16 MOT defect notes
- DVSA code
- 6.1.2 (a)
What it means
An exhaust mount is worn or the system is insecure/leaking. That can worsen noise, fumes and later emissions failures.
Why it happens
Rubber hangers perish and joints loosen with heat cycles and corrosion.
Buyer tip
Look under the car for hanging sections, cracked rubbers and sooty leak marks at joints.
Severity
Often a recurring model pattern
Steering lock not functioning
- Recorded
- 8 MOT defect notes
- DVSA code
- 7.3 (a)
What it means
The steering lock does not operate as designed when the ignition is off.
Why it happens
Worn lock barrels or column lock mechanisms stop the lock engaging cleanly.
Buyer tip
Test lock engagement and factor in lock/barrel repair costs on older keys.
Severity
Often a recurring model pattern

Buying a used BMW 218: practical MOT checks
- Inspect 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.
- Check headlamp aim on a wall or ask the seller when bulbs were last adjusted, because aim faults appear thousands of times in the records.
- Look underneath for light oil misting on shock absorbers and confirm the windscreen washer sprays correctly on both sides.
- With 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.
