Diesel Land Rover Discovery Sport: MOT pass rate
85.1% of diesel Land Rover Discovery Sports pass the MOT first time, measured across 88,012 DVSA tests on that fuel type alone. Average mileage at test was 65,201.
Diesel against the other Land Rover Discovery Sport versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 85.1% | 88,012 |
| Petrol | 87.2% | 3,133 |
| All Land Rover Discovery Sport | 85.2% | 91,165 |
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 Land Rover Discovery Sport specifically, petrol is the strongest at 87.2%, and this diesel version sits 0.1 points below the 85.2% 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 Land Rover Discovery Sport had covered 65,201 miles at test, against 41,826 for the petrol. That is a shade above the middle of the range, still ordinary wear rather than a red flag, but worth checking against the service book for the car's age.
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 Land Rover Discovery Sport page separate age from fuel if you want to isolate one.
