Diesel Jaguar S-Type: MOT pass rate

66.3% of diesel Jaguar S-Types pass the MOT first time, measured across 3,443 DVSA tests on that fuel type alone. Average mileage at test was 100,495.

Diesel against the other Jaguar S-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 S-Type specifically, petrol is the strongest at 67.2%, and this diesel version sits 0.6 points below the 66.9% model average.

What it means if you are buying one

There is little to choose between fuel types on this model, so decide on running costs and mileage rather than MOT record. 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 S-Type had covered 100,495 miles at test, against 90,621 for the petrol. That is above average and into the range where cambelts and water pumps are due if they have not already been done, so ask for the service history rather than take the mileage on trust.

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 S-Type page separate age from fuel if you want to isolate one.

Most common MOT failures on a diesel Jaguar S-Type

1. Steering rack gaiter or ball joint dust cover missing or no longer prevents the ingress of dirt etc, 8.6% of tests (11.6x the national rate for this defect)
2. 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, 3% of tests (11.16x the national rate for this defect)
3. A suspension joint dust cover missing or no longer prevents the ingress of dirt etc, 19.3% of tests (10.49x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3% of tests (7.14x the national rate for this defect)
5. 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, 4% of tests (4.28x the national rate for this defect)
6. Significant brake effort recorded with no brake applied indicating a binding brake, 3.3% of tests (3.18x the national rate for this defect)
7. The aim of a headlamp is not within limits laid down in the requirements, 6.3% of tests (2.7x the national rate for this defect)
8. A suspension pin, bush or joint excessively worn, 10% of tests (1.99x the national rate for this defect)
9. A tyre cords visible or damaged, 3.1% of tests (1.86x the national rate for this defect)
10. Wiper blade missing or obviously not clearing the windscreen, 3.3% of tests (1.72x the national rate for this defect)

From 3,488 DVSA-tracked diesel Jaguar S-Type tests, 2024, split out from the Jaguar S-Type's other fuel types. DVSA testers marked 4.83% 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, 6.7% of tests (4.4x the national rate for this defect), also fails
4. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 4.1% of tests (3.7x the national rate for this defect)
