2000 BMW Z3 — MOT failures & pass rate
12,275 MOT tests on the 2000 BMW Z3 are in this dataset, and 77.9% of them passed. Coupes & convertibles of a similar age fail at 22.3%, so the 2000 Z3 sits squarely on the average. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (9.4%) and brakes (9.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, washers and catalyst emissions — rigid brake pipes alone was recorded 633 times.
Condition tracks the odometer closely. Failures run at 9.8% in the 0-30k band and 30.5% in the 150k+ band, a 20.7-point spread — more than double.
Advisories point at the next bill rather than this one: brakes was flagged on 33.9% of tests without failing them.
The trend is improving — the fail rate fell from 23.8% in 2021 to 21.3% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

| 6 | Body, structure & corrosion | 9.6% | 1,172 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 523 | 9.8% |
| 30-60k | 2,393 | 15.3% |

What to check before buying a 2000 Z3
On a 2000 Z3, lighting & signalling is what the MOT record says goes wrong most — it appeared in 9.4% of tests. Check these areas before you commit.
- Lighting & signalling (9.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.4% 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 (8.8% 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.
