1995 Jaguar XJ — MOT failures & pass rate
The 1995 Jaguar XJ passed 80.0% of its 2,953 recorded MOT tests. Executive cars of a similar age fail 21.3% of the time, so this is 1.3pp better than the group it competes with. Failures cluster in lighting & signalling, emissions & environmental and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (8.4%) and emissions & environmental (7.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, headlamp aim and washers — catalyst emissions alone was recorded 328 times.
Condition tracks the odometer closely. Failures run at 9.8% in the 0-30k band and 25.7% in the 150k+ band, a 16.0-point spread — more than double.
Suspension is the most common advisory, noted on 39.8% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.9% in 2021 to 19.0% in 2025, as the worst-kept examples leave the fleet.

Most common specific failures
The exact components most often recorded as failures — more specific than the categories above.
| # | Failure item | Times recorded |
|---|---|---|
| 1 | Catalyst emissions | 328 |
| 2 | Headlamp aim | 118 |

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 | 39.8% | 1,174 |
| 2 | Brakes | 21.1% | 624 |
| 3 | Tyres | 17.8% | 526 |
| 4 | Body, structure & corrosion | 15.5% | 459 |
| 5 | Emissions & environmental | 15.5% | 457 |
| 6 | Other defects | 9.5% | 281 |
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 | 82 | 9.8% |
| 30-60k | 328 | 12.8% |
| 60-90k | 739 | 18.7% |
| 90-120k | 835 | 19.2% |
| 120-150k | 568 | 24.1% |
| 150k+ | 377 | 25.7% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 785 | 21.9% |
| 2022 | 640 | 18.9% |
| 2023 | 594 | 20.9% |

What to check before buying a 1995 XJ
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 8.4% of tests. Start there.
- Lighting & signalling (8.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (7.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Suspension (6.6% 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.
