2009 BMW X3 — MOT failures & pass rate
8,833 MOT tests on the 2009 BMW X3 are in this dataset, and 80.5% of them passed. That is 6.7 percentage points better than mid-size SUVs of a similar age, which fail at 26.2%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (7.9%) and suspension (7.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, coil spring and tread depth — headlamp aim alone was recorded 406 times.
Condition tracks the odometer closely. Failures run at 12.5% in the 0-30k band and 22.1% in the 150k+ band, a 9.6-point spread.
Tyres is the most common advisory, noted on 26.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 18.1% of tests failed in 2021 against 19.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2009 X3
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 7.9% of tests. Start there.
- Lighting & signalling (7.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (7.7% 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.
- Brakes (7.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
