Diesel against the other Jaguar Xf versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 77.8% | 88,510 |
| Petrol | 84.5% | 8,966 |
| All Jaguar Xf | 78.4% | 97,477 |
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 Xf specifically, petrol is the strongest at 84.5%, and this diesel version sits 0.6 points below the 78.4% 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. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel Jaguar Xf had covered 90,816 miles at test, against 60,919 for the petrol. That is above average, the point where suspension bushes, drop links and exhaust corrosion start showing up as advisories before they become failures.
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 Xf page separate age from fuel if you want to isolate one.
