2022 BMW Z4 — MOT failures & pass rate
1,057 MOT tests on the 2022 BMW Z4 are in this dataset, and 94.0% of them passed. Against coupes & convertibles of a similar age (7.9% fail rate), the 2022 Z4 comes out 1.9pp better. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
One area stands out: tyres, recorded in 4.8% of tests against 1.0% for the next-worst category.
At component level the recurring items are headlamp aim, registration plates and tread depth — headlamp aim alone was recorded 13 times.
Tyres is the most common advisory, noted on 18.4% of tests — work that passed today but is likely due soon.

| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 950 | 5.6% |
| 30-60k | 104 | 9.6% |
Failure rate by age

| 2024 | 68 | 2.9% |
| 2025 | 987 | 6.2% |
What to check before buying a 2022 Z4
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.8% of tests. Start there.
- Tyres (4.8% 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.
- Lighting & signalling (1.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (0.7% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
