Diesel Jaguar X-Type: MOT pass rate

62.6% of diesel Jaguar X-Types pass the MOT first time, measured across 15,819 DVSA tests on that fuel type alone. Average mileage at test was 116,014.

Diesel against the other Jaguar X-Type versions

Why the fuel type changes the number

Diesels carry DPFs, EGR valves and stricter smoke limits, so emissions and exhaust faults account for failures petrol cars never see.

On the Jaguar X-Type specifically, petrol is the strongest at 66%, and this diesel version sits 1.2 points below the 63.8% model average.

What it means if you are buying one

The diesel Jaguar X-Type fails more often than the model average, so budget for the items that catch this fuel type and treat a fresh MOT as worth paying for. Buying a damaged one? run it through the analyzer, check the exact car, decode the VIN and check the mileage before you bid.

Mileage is part of the answer

The average diesel Jaguar X-Type had covered 116,014 miles at test, against 87,189 for the petrol. That is high mileage, so timing belts, clutches, suspension bushes and corrosion are the items worth budgeting for rather than the MOT itself.

Fuel type and mileage are tangled together: diesels are usually bought by higher-mileage drivers, so some of any gap between fuels is the miles rather than the engine. The per-year figures on the Jaguar X-Type page separate age from fuel if you want to isolate one.

Most common MOT failures on a diesel Jaguar X-Type

1. The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, 4.5% of tests (16.88x the national rate for this defect)
2. A suspension component excessively damaged or corroded, 4.7% of tests (13.33x the national rate for this defect)
3. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 11.4% of tests (12.05x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 4.3% of tests (10.39x the national rate for this defect)
5. Smoke opacity levels exceed the manufacturer's specified limit, 2.6% of tests (9.73x the national rate for this defect)
6. A suspension joint dust cover missing or no longer prevents the ingress of dirt etc, 4.5% of tests (2.46x the national rate for this defect)
7. Parking brake efficiency below minimum requirement, 3% of tests (2.31x the national rate for this defect)
8. A tyre cords visible or damaged, 3.6% of tests (2.14x the national rate for this defect)
9. A suspension pin, bush or joint excessively worn, 10% of tests (2x the national rate for this defect)
10. The aim of a headlamp is not within limits laid down in the requirements, 4% of tests (1.69x the national rate for this defect)

From 16,018 DVSA-tracked diesel Jaguar X-Type tests, 2024, split out from the Jaguar X-Type's other fuel types. DVSA testers marked 4.72% of these flagged defects as "dangerous", against 5.11% nationally.

3. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 10% of tests (6.6x the national rate for this defect), also fails
4. A spring or spring component fractured or seriously weakened, 21.4% of tests (4.53x the national rate for this defect)
5. Lamp emitted colour, position or intensity not in accordance with the requirements, 4.4% of tests (3.18x the national rate for this defect)
