1996 Citroen Zx — MOT failures & pass rate
538 MOT tests on the 1996 Citroen Zx are in this dataset, and 71.4% of them passed. That is 3.8 percentage points worse than all cars of a similar age, which fail at 24.8%. Failures cluster in brakes, suspension and lighting & signalling.
What the MOT record shows
No single area dominates — brakes (13.8%) and suspension (13.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, component mounting prescribed areas and catalyst emissions — service brake performance alone was recorded 36 times.
Mileage is the strongest signal on the record: 24.7% of 30-60k cars fail, rising to 34.2% once past 150k.
Advisories point at the next bill rather than this one: suspension was flagged on 35.1% of tests without failing them.
The trend is improving — the fail rate fell from 32.0% in 2021 to 25.4% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 35.1% | 189 |
| 2 | Brakes | 29.2% | 157 |
| 3 | Tyres | 26.2% | 141 |
| 4 | Emissions & environmental | 25.3% | 136 |
| 5 | Body, structure & corrosion | 22.3% | 120 |
| 6 | Other defects | 18.4% | 99 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 89 | 24.7% |
| 60-90k | 115 | 27.8% |
| 90-120k | 110 | 26.4% |
| 120-150k | 99 | 28.3% |
| 150k+ | 117 | 34.2% |
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Diesel | 365 | 28.8% |
| Petrol | 173 | 28.3% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1996 Zx
On a 1996 Zx, brakes is what the MOT record says goes wrong most — it appeared in 13.8% of tests. Check these areas before you commit.
- Brakes (13.8% 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 (13.0% 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 (11.7% 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.
