Most common MOT failures on the 1997 BMW Z3
Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits was the most common single reason a 1997 BMW Z3 failed, on 12.2% of about 500 failed tests. By area of the car, lamps, reflectors and electrical equipment failed most often (39.2% of failed tests; all 1997 cars 41.8%). 4.9% of tests found at least one dangerous defect, against 6.0% for all cars first registered in 1997. A failed test can have several defects, so shares add up to more than 100%.

Registered: cars on the DVLA record at the end of the year they were first registered (these counts start in 2014, so older years show a dash). Left: licensed or declared SORN at the end of 2025. Both cover the United Kingdom. Pass rate: first-time passes at normal MOT tests in Great Britain in 2025; all cars: every car first registered the same year.
Data sources and methodology
| Figures | Source | Period | Records | Updated |
|---|---|---|---|---|
| MOT results and mileage | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 1,523 MOT tests of 1997 BMW Z3 cars | 15 September 2026 |

- MOT figures cover normal tests in Great Britain in 2025 of BMW Z3 cars first registered in 1997; retests are excluded. “All cars” means every car we match to a model, first registered in 1997.
- Year of first registration is DVSA’s first-use date: when the car was first registered, in the UK or abroad.
- Defects and advisories are DVSA’s descriptions made readable. Where on the car a defect was found (side, front or rear) is ignored, so the same fault on any wheel counts once per test.
- Mileage is the odometer reading at each car’s latest normal MOT of the year, as recorded by the tester. A few readings are in kilometres or mistyped; percentiles are not thrown by a handful of outliers.
- Cars on the record come from DfT table VEH0124 and cover the United Kingdom, including Northern Ireland; MOT figures cover Great Britain only.
- DVSA records the model name typed in at the test. We match those names to DVLA’s generic models, so a handful of tests may be counted under a close relative.
