The fail item testers record most often at 3 years: tyre condition: has a cut in excess of the requirements deep enough to reach the ply or cords, on 3.2 per 100 MOTs (all cars 1.8).
The most common advisory or minor defect: tread depth: worn close to legal limit/worn on edge, on 11.6 per 100 MOTs.

Problems by part at 3 years

How many of every 100 MOTs found a fail, or an advisory or minor defect, in each area. A test with faults in two areas counts in both.

Early warnings: advisories and minor defects at 3 years

Advisories and minor defects are recorded, but the car still passes. Across all cars, a part with an advisory or minor defect failed at the next MOT 5.5 times in 100 (n=88,666,940 pairs of consecutive MOTs), against 0.3 times in 100 when the same part had none (n=12,936,860,350).

Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

Mileage

At 3 years, BMW X3 cars showing under 30,000 miles failed 8.3% of MOTs (n=28,908); the band that failed most, 30,000 to 60,000 miles, failed 12.0% (n=12,771). For pass and fail rates by age, see BMW X3 MOT fail rates.

What to check on a viewing

On the BMW X3, testers most often record tyre condition: has a cut in excess of the requirements deep enough to reach the ply or cords; tyre with cords exposed; tyre tread below 1.6 mm. Look at these first, then the areas below.

Tyres

Check the tread across the full width of all four tyres, and the spare if there is one.
Look for cuts, bulges and cracking in the sidewalls.
Wear on one edge only can point to worn suspension or the tracking being out.

Lights and electrics

With someone outside, try every light: dipped and main beam, indicators, brake lights, fog lights and number plate lamps.
Check that the warning lights come on with the ignition and go out once the engine runs.
Look for misted, cracked or yellowed headlamp lenses.

Windscreen, wipers and mirrors

Look for chips or cracks in the windscreen, above all in front of the driver.
Run the wipers and washers: they should clear the screen without smearing.
Check that the mirrors are present, secure and not cracked.

Ask for the car's MOT history and service record: advisories that repeat from one year to the next show what has been left. GOV.UK MOT history.

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

The all cars figures cover all class 4 vehicles (cars and light vans) tested at the same age.
