2014 BMW X4 — MOT failures & pass rate
Across 4,342 MOT tests, the 2014 BMW X4 recorded an 85.2% pass rate. That is 3.1 percentage points better than mid-size SUVs of a similar age, which fail at 17.9%. Failures cluster in tyres, suspension and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (6.0%) and suspension (4.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are coil spring, tread depth and brake pads — coil spring alone was recorded 179 times.
Condition tracks the odometer closely. Failures run at 8.4% in the 0-30k band and 19.6% in the 150k+ band, a 11.2-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 22.0% of tests without failing them.

What to check before buying a 2014 X4
On a 2014 X4, tyres is what the MOT record says goes wrong most — it appeared in 6.0% of tests. Check these areas before you commit.
- Tyres (6.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Suspension (4.7% 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.
- Lighting & signalling (3.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
