1994 Citroen Ax — MOT failures & pass rate
The 1994 Citroen Ax passed 74.2% of its 294 recorded MOT tests. All cars of a similar age fail 23.9% of the time, so this is 1.9pp worse than the group it competes with. Failures cluster in lighting & signalling, emissions & environmental and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 17.3% of tests against 9.9% for the next-worst category.
At component level the recurring items are catalyst emissions, headlamp aim and component mounting prescribed areas — catalyst emissions alone was recorded 32 times.
Condition tracks the odometer closely. Failures run at 27.6% in the 30-60k band and 18.8% in the 120-150k band, a 8.9-point spread.
Suspension is the most common advisory, noted on 25.5% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 27.4% in 2021 to 24.4% in 2025, as the worst-kept examples leave the fleet.

| 30-60k | 105 | 27.6% |
| 60-90k | 82 | 26.8% |
| 90-120k | 55 | 27.3% |
| 120-150k | 32 | 18.8% |
Trend over time

What to check before buying a 1994 Ax
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 17.3% of tests. Start there.
- Lighting & signalling (17.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (9.9% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Suspension (9.9% 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.
