2006 BMW X3 — MOT failures & pass rate
22,474 MOT tests on the 2006 BMW X3 are in this dataset, and 77.4% of them passed. That is 5.2 percentage points better than mid-size SUVs of a similar age, which fail at 27.7%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (11.8%) and suspension (9.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, position lamp and tread depth — headlamp aim alone was recorded 1,497 times.
Mileage matters less than usual here: the 2006 X3 fails 27.3% of the time in the 0-30k band and 24.1% at 150k+, a spread of only 3.2 points.
Fuel type barely separates them — petrol fails 22.1% of the time against 22.6% for diesel.
Advisories point at the next bill rather than this one: tyres was flagged on 28.5% of tests without failing them.
The trend is worsening — 21.5% of tests failed in 2021 against 23.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2006 X3
On a 2006 X3, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.8% of tests. Check these areas before you commit.
- Lighting & signalling (11.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.9% 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 (8.6% 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.
