Diesel against the other DS Ds4 versions
| Fuel | Pass rate | Tests |
|---|---|---|
| Diesel | 72.8% | 3,552 |
| Petrol | 74.3% | 914 |
| All DS Ds4 | 73.1% | 4,466 |
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 DS Ds4 specifically, petrol is the strongest at 74.3%, and this diesel version sits 0.3 points below the 73.1% 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 DS Ds4 had covered 64,158 miles at test, against 51,433 for the petrol. That is around average, so condition and service history will tell you more than the odometer does.
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 DS Ds4 page separate age from fuel if you want to isolate one.
