2003 BMW X5 — MOT failures & pass rate
The 2003 BMW X5 passed 73.1% of its 15,764 recorded MOT tests. That is 1.5 percentage points worse than large SUVs of a similar age, which fail at 25.4%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (15.8%) and brakes (14.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are ball joint, headlamp aim and pins and bushes — ball joint alone was recorded 1,282 times.
Condition tracks the odometer closely. Failures run at 31.1% in the 0-30k band and 26.6% in the 150k+ band, a 4.6-point spread.
Fuel type barely separates them — petrol fails 26.6% of the time against 27.1% for diesel.
Brakes is the most common advisory, noted on 37.6% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 28.2% in 2021 to 24.7% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2003 X5
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 15.8% of tests. Start there.
- Lighting & signalling (15.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (14.6% 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.
- Suspension (12.2% 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.
