Diesel against the other DS Ds7 versions
| Fuel | Pass rate | Tests |

| Diesel | 77.4% | 292 |
| All DS Ds7 | 84.2% | 1,824 |
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 Ds7 specifically, petrol is the strongest at 85.4%, and this diesel version sits 6.8 points below the 84.2% model average.
What it means if you are buying one
The diesel DS Ds7 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. Check the exact car, decode the VIN and check the mileage before you bid.
Mileage is part of the answer
The average diesel DS Ds7 had covered 45,701 miles at test, against 40,175 for the petrol. That is below average for a car this age, worth a mileage-consistency check since an unusually low reading is sometimes clocking rather than luck.
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 Ds7 page separate age from fuel if you want to isolate one.
