2002 BMW 3 Series — MOT failures & pass rate
Across 59,483 MOT tests, the 2002 BMW 3 Series recorded a 76.1% pass rate. Executive cars of a similar age fail at 24.3%, so the 2002 3 Series sits squarely on the average. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (12.2%) and lighting & signalling (11.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, rbt (sp) and rigid brake pipes — headlamp aim alone was recorded 3,848 times.
Condition tracks the odometer closely. Failures run at 11.9% in the 0-30k band and 26.6% in the 150k+ band, a 14.6-point spread — more than double.
Split by fuel, diesel examples fail 2.9pp more often than petrol ones (26.4% vs 23.5%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 38.1% of tests without failing them.
The trend is improving — the fail rate fell from 25.3% in 2021 to 22.2% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2002 3 Series
On a 2002 3 Series, brakes is what the MOT record says goes wrong most — it appeared in 12.2% of tests. Check these areas before you commit.
- Brakes (12.2% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (11.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
